Seeing Stars in Vision Explained

Seeing Stars in Vision Phosphene

Have you ever seen spots swimming across your eyes?
This phenomenon of seeing stars in vision is called a phosphene.

Did you ever close your eyes and push on them with your fingers as a child to see waves and patterns of color float across your eyelids?  Perhaps more commonly for adults, have you ever stood up suddenly from reclining or laying down and seen spots swimming across your vision?  Or maybe you suffer from migraines that begin as flashes and spots of light crossing the visual field.  Hopefully you have never been knocked on the head hard enough to cause flashes of light, but that is another way that you may see strange spots that don’t actually exist.  This phenomenon of “seeing stars in vision” is called a “phosphene,” and is the experience of seeing light when no light is actually entering the eye.

How can I see light where no light is present?

There are several ways that the eye can see light where no light is present.  In order for us to see, our retina must be stimulated by light waves, which our brain then translates into an image.  But the retina can also be stimulated physically, electrically, and magnetically.  Most phosphenes that people experience are physically induced. When you rub your eyes or close them and put pressure on them, you activate cells in the retina, which the brain is required to interpret as a visual signal.  Thus, you see waves of color and patterns of black and white.  Since there are no light waves actually entering the eye, the brain cannot create a picture (like a floating meatball sandwich), so you simply see patterns, colors and spots. Other physically induced phosphenes can include seeing spots when you sneeze – sneezing puts a lot of pressure on the eyes and on the light-receiving cells in the eyes.

Fluctuation in blood pressure

When you have been in a reclined position for some time and then stand up, you may experience a drop in blood pressure.  The eye has a very high metabolism, so that drop in blood pressure results in a loss of oxygen to the retina, which can cause it to misfire signals to the brain.  On an opposite note, if you are experiencing seeing stars in vision while pregnant without having just stood up, this can be a signal of pre-eclampsia, a serious condition involving high blood pressure, and you should see your care provider immediately about this concern.  Another physically induced phosphene is caused by migraines.  Migraines are spasms of blood vessels in the brain, and flashes and spots that come on before a migraine are caused by spasms of blood vessels in the retina.

A bump on the head

Finally, seeing spots when you have been hit in the head is not necessarily caused by physical stimulation to the retina, but often because the part of the brain that processes signals from the retina and produces images, known as the occipital lobe, gets bumped.  This can irritate the visual cortex, located inside the occipital lobe, and in the same way that physical stimulation of the retina produces spots, physically stimulates the cells in the visual cortex to produce spots and flashes.

Seeing stars is generally not a concern for eye health

Usually, seeing spots or flashes of light is not a concern and can be explained by one of the reasons above.  However, if you are experiencing a sudden increase of flashes or spots, it can be a sign of a detached retina, which is a medical emergency because it can lead to permanent blindness within a matter of hours.  Contact your eye doctor immediately, and if you cannot reach the eye doctor, go to the emergency room.

Vision Therapy for Children

Vision therapy is like physical therapy for the eyes.

Many children are involved in sports during the school year. Sports require a great deal of hand-eye coordination as well as good vision in order to perform well. If your child is consistently under-performing in a sport that he or she usually does well in, could a vision problem be the issue?

Some vision skills that children require to play sports include:

  • Hand-eye coordination: Using visual information to move the hands, such as when aiming and swinging a bat.
  • Visual acuity: Seeing objects clearly at different distances, i.e. seeing a hole at a distance and close-up while golfing.
  • Eye teaming: Seeing depth and accurately judging distance while using both eyes, such as when judging how hard to kick a soccer ball.
  • Eye tracking: Keeping eyes together on a moving target or while looking from one object to another, such as while following a volleyball during a game.
  • Eye focusing: Being able to quickly keep an object clearly in focus while it changes distance, like when watching other players during a basketball game.

If any of these vision skills are lacking or underdeveloped, children can have a difficult time in sports and may not be playing the best that they could be. For example, the basketball may be thrown consistently too softly and always miss the hoop by a few inches in the front if eye teaming is poor. If the student has poor hand-eye coordination, they may understand where the volleyball is at but be unable to hit it with the correct part of their arm, causing the ball to hit the net instead of going over it.

How Can Uptown Eye Care Help?

This is where Uptown Eye Care can help. If you suspect your child has a vision problem and it is affecting the sports that the child is playing, bring him or her in for a vision exam. The specific visual problem can be pinpointed and a treatment selected. Examples of treatments that may be prescribed include a glasses or contacts prescription and vision therapy (sometimes called “vision training”). Vision therapy is like physical therapy for the eyes – it may sometimes involve exercises that work out the physical muscles of the eyes but mainly works on the “mental muscles” of the mind that are responsible for translating and interpreting the visual information sent by the optic nerve.

It is important to be sure that your child is wearing appropriate eyewear for the sports that he or she is participating in. Without protective eyewear, the chances of injury increase. Children would benefit from wearing protective eyewear in any sport that includes moving objects or physical contact, such as football, hockey, soccer, tennis, and martial arts. For sports played outside, protection from the sun is also a must. UV rays can cause damage to their eyes, so protective eyewear or sunglasses with UV-blocking coatings are recommended. Visit our clinic to view a selection of protective eyewear and sunglasses today!

What is a Paraoptometric?

Paraoptometrics are allied health professionals who assist optometrists in providing their highest level of vision care to patients. They extend the optometrist’s capabilities by assuming routine and technical aspects of vision care services. Paraoptometrics are to optometrists what paralegals are to lawyers.

Paraoptometrics perform a variety of duties in the optometric practice. They take care of front desk procedures, billing and coding of insurance claims and patient scheduling.  They may also perform more clinical duties such as pre-testing patients, contact lens procedures, special testing and vision therapy. Paraoptometrics are also trained in ophthalmic optics and skilled at the selection, fitting and dispensing of eyewear.

As part of the vision care team, paraoptometrics help build patient confidence while working directly with an optometrist. A well-trained paraoptometric staff builds a clinic-patient relationship that is not only invaluable to the optometrist, but also ensures a high level of service resulting in patient satisfaction.

The American Optometric Association’s Paraoptometric Recognition Week

The American Optometric Association has designated September 14-20, 2014 as Paraoptometric Recognition Week. Now in its twelfth year, the recognition week is designed to honor paraoptometrics for their dedication to the patients they serve and to the profession of optometry.

Paraoptometrics are key members of the eye care delivery team in optometric offices all across the country. Their role is even more critical to providing the best patient care possible in today’s health care environment.

Linda Rodrigues, CPO, Paraoptometric Resource Center Executive Committee chair, recognized the important role of staff for a successful practice by stating, “Paraoptometrics are an essential part of the eye-care team. The potential of a well-trained optometric staff is of utmost importance and the formula to achieve a successful optometric practice. Optometrists who recognize their paraoptometric staff for their dedication, knowledge and professionalism are rewarded with satisfied patients and practice growth.”

Uptown Eye Care located at 560 Cedar Street, Monticello, MN (https://plus NULL.google NULL.com/b/102384119795973095334/+UptownEyeCare/about) plans to celebrate the week recognizing their CPO & CPOA certified staff.

Healthy Eye Care Tips for College Students

Healthy Eye Care Tips for College StudentsThe start of the college semester is just around the corner, and right now most college-bound students are busy packing boxes, preparing schedules, and cringing at the price of textbooks.  For those students’ eyes, college means sleep deprivation, lots of close-up work, screen time galore, and close contact with other germs.  This can lead to eye fatigue, dry eyes and conjunctivitis or other eye diseases.  To help keep your eyes in top shape for the course load ahead, put the following tips into practice.

1.  Take frequent breaks.  Long stretches of time spent staring at a screen, reading a book, or completing homework can take their toll on your eyes, causing fatigue and dry eyes.  To prevent this, remember the 20-20-20 rule: after 20 minutes, look away at something at least 20 feet away, for 20 seconds.  If you are still getting dry eyes even after following this rule, keep some lubricating eye drops on hand (but do not overuse the eye drops; be sure to follow the directions on the bottle).  Try studying outside, as well, which may help you to not lean in so close to your books or computer and prevent fatigued eyes.

2.  Don’t wear your contact lenses in the pool or shower.  Contact lenses are meant for contact with your eyes and sterile liquid only.  Wearing them in the pool can introduce germs or parasites that can populate behind the lens and cause some pretty serious eye infections.  The same thing can happen in the shower (which, especially if it is a community shower, hosts lots of germs anyway).  Don’t wash your lenses with water, either; only use contact lens solution.

3.  Don’t over-wear your contact lenses.  Over-wearing the contact lenses for longer than they are designed for (typically 8-12 hours) produces the same effect as sleeping in them.  Your eyes become deprived of oxygen, and, as a result, your vision may become blurred and inflammation may set in.  If you don’t have a backup pair of glasses, you may want to purchase some before school starts.  That way, as you approach the end of your contact lens usability for the day, you can switch to glasses and prevent negative effects.  Glasses are also great for those days when you are late to class and don’t have the time to put your contact lenses in.

4.  For the ladies, use your own makeup.  You may share everything with your college roommates, from food to clothes to pens to shoes, but don’t share your makeup.  Makeup, especially mascara, is a breeding ground for bacteria, and while your eyes may not be affected by what is living on your mascara or eyeshadow brush, they may get an infection from what is living on your roommate’s brush.  Opt for the “natural look” instead of risking an infection from someone else’s makeup, because the “conjunctivitis look” is not pretty!

5.  Wash your hands frequently.  Another way of getting an eye infection in college is by touching your face (like sleepily rubbing your eyes) when your hands are not clean.  Almost everything you touch will have been touched by plenty of other students, and you don’t want those germs waiting on your hands to leap into your eyes or mouth.  This will also help prevent general illness, too.

6.  Wear eye protection during sports.  From pool chlorine and germs to flying balls and flying elbows, your eyes are at risk of injury during sports.  Make sure to wear the appropriate eyewear for your sport, and consider wearing sports glasses to protect your eyes even if they are not required for your sport.  If you wear contact lenses or glasses, sports glasses with a prescription lens is a great option to avoid broken glasses or injury from the contact lens if you are hit in the face.

nutrition for cataract prevention

Nutrition is an important part of cataract prevention and maintaining overall eye health.

Cataracts occur when the natural lens of the eye, located behind the pupil and iris, becomes cloudy. This can result in blurriness, sensitivity to light and vision loss. Cataracts are a leading cause of blindness and affect millions of people in the United States, especially those over the age of 40. The only way to treat cataracts is to remove the clouded lens through surgery. The good news is that cataracts are preventable to a certain extent. Follow our tips to ensure that you are doing your part to prevent cataracts.

1. Wear sunglasses with 100% UV blocking. Exposure to the sun’s ultraviolet rays harms eyes in many ways and may be one major risk factor in forming cataracts. Consider wearing a wide-brimmed hat, as well, to physically block sunlight from your face.

2. Stop smoking and reduce alcohol intake. Cigarette smoke is extremely harmful in many ways and has been linked to an increased chance of developing cataracts. Quit the habit, and your eyes, body, and those around you will thank you. Consume alcohol in moderation, as well. Just like cigarette smoke, excessive alcohol consumption leads to a host of health issues, including a greater chance of forming cataracts.

3. Manage your health problems. A higher risk of forming cataracts has been linked to diabetes and hypertension. By managing these health issues, you may also lower your risk of forming cataracts.

4. Eat right. This step is important for several reasons. First, obesity is a risk factor for cataracts. If you maintain a healthy weight, you cut out that particular risk factor. Second, studies have found that certain nutrients can help prevent cataracts from forming. These nutrients include vitamin E, lutein, zeaxanthin, vitamin C, and omega-3 fatty acids. Many of these nutrients can be found in foods like eggs, sunflower seeds, almonds, kale, spinach, and fresh fruits and vegetables. By eating a lot of fresh fruits and veggies, you will also take in a large amount of antioxidants, which may also help prevent cataracts. Plus, a healthy diet will help manage other health issues that may be linked to forming cataracts (such as in tip 3, above).

5. Have regular eye exams. Your eye doctor will be able to look for cataracts before the cataracts start affecting your ability to perform daily tasks. This can lead to treatment and prevent your cataracts from causing blindness! Schedule an eye exam now with one of our eye doctors if you have a concern about your vision or if it has been more than one or two years since you last saw an eye doctor.

Protecting Your Eyes in a Swimming Pool

swimming pool eye health

Swim goggles are a great way to protect your eyes from chlorine and other irritants.

As summer draws near and the temperature heats up, many people will begin heading to pools to cool off.  Nothing is more refreshing than a leisurely dip into a cool pool on a hot summer day.  But the consequence can be stinging, red eyes, especially in an indoor pool or a pool with a higher level of chlorine.

Why does the pool water affect our eyes?  What can be done about irritated eyes?

There are several reasons why pool water can have a negative effect on our eyes.  First, the water strips away the tear film that coats our eyeballs and protects it from germs.  When that tear film is gone, germs can enter the eye and cause an infection in the eye, or conjunctivitis.  In fact, the spread of conjunctivitis from pool usage is more common than one may think.  Even in chemically treated water, the chlorine does not kill all the germs, nor does it kill germs instantly, so they can still be transferred from person to person.

Second, the chlorine in pools interacts with organic compounds in the water (such as what comes off of swimmers) and creates new compounds, known as chloramines, which act as irritants.  These chloramines also enter the air and are the source of the familiar “pool smell.” For swimmers, once the tear film is gone, the chloramines can enter the eyes and cause stinging, blurry vision, and red eyes.  They also can irritate the skin, and they can irritate the lungs when they are airborne, such as at an indoor pool.

Saltwater pools can also be irritating to eyes, since the salt is turned into chlorine by a generator.  However, some swimmers say that saltwater pools do prove to be gentler on eyes and skin than traditional chlorine pools.  The best thing to do, whether you are swimming in a chlorine pool or saltwater pool (or swimming anywhere), is to wear goggles.  Goggles will protect your eyes from germs, from bugs, from chemical irritants, and from the water removing your tear film.  Also, if you wear contacts, you should remove them when swimming because algae and germs can get stuck between the contact lens and your eyeball, causing infection.  Again, goggles will provide the best protection against infection, but remove contact lenses anyway.

Finally, if your eyes do get irritated, flush them with saline eyedrops or with tap water.  If signs of an infection start to appear or the irritation does not go away within a day, you ought to see your eye doctor.

choosing eye glasses frames

Choosing the right eye glasses to “frame your face” can make all the difference.

Choosing Eye Glasses to Enhance Your Face Shape

Did you know that, just like hairstyles, the right glasses can also enhance your face shape? Whether you have a rectangle or oval face, a heart-shaped or a round face, there is a pair of frames out there that perfectly complements your face shape. If you take the time to play up your face’s best features with your hair and, if you are female, with your makeup, take the time to choose the right pair of glasses, as well!

First, look at your face in the mirror and determine your face shape. Do you have a face that is broader at the temple and narrower at the chin? You may have an inverted triangle or heart shape. Is your jaw line angular, and your jaw and forehead about the same width? You may have a square face. Are your forehead and jaw lines curved, and your face long? You may have an oval face. If your face is equally long and wide, and the lines soft and curved, you may have a round face. You may also have a combination of face shapes. If you absolutely cannot decide which shape you have, simply decide whether your face is more angular or curved. That will be the top determiner as to what pair of glasses complements your face.

Create Contrast

You will want to choose a pair of glasses that contrasts with the shape of your face. If you have a round face, for example, you will want a pair with boxy angles. If you have a square face, you will want a pair that is curvy. If you have a wide forehead but narrow chin, you will want a pair that draws attention downward toward your chin, such as one that has a colored bottom rim. Following are some suggestions for specific face shapes.

For heart-shaped faces, you may want to try a pair of rimless glasses, which will appear light and airy, detracting from your forehead. Glasses that have lenses that are wider at the bottom will also help balance your face, as well as glasses that have a colored bottom rim.

For round faces, try rectangular-shaped frames. You will want the frame to be narrow and wide to create the illusion of a longer, thinner face. Bold, dark frames will help define the face, as well.

For square faces, choose a pair of frames that speaks curves. Round or oval lenses work well, as do lenses that seem to sweep up. Lighter colors add softness to the face. Rimless frames may also work well.

For oval faces, almost any pair of glasses will work. Oval faces are naturally balanced, so choose a pair that keeps that natural balance and is not too small or too big for your face. Try to find a pair that is as wide as or wider than your face, and have fun playing with different shapes.

The right pair of glasses will help balance your face shape out, whether you are a man or a woman. Choose a pair to go with your face shape, and you will help your face to look even more fantastic!

healthy vision month

May is Healthy Vision Month. Read our healthy eye tips and make some time to take care of your vision.

How healthy is your vision?  Have you taken any recent steps to prevent vision problems, or taken steps to treat any vision problems you may be experiencing? There is no better time to start taking care of your vision than now! May was Healthy Vision Month; so let’s keep it going by setting aside some time to follow our tips for healthy vision.

Healthy Vision Month – Eye Care Tips

  • Set up an appointment with your eye doctor to have a vision exam done.  This is the most important step in maintaining your vision’s health; your eye doctor can treat problems that you are experiencing in your vision and can also detect problems that you may not be aware of.  Steps can then be taken to prevent problems from becoming worse (or prevent problems from occurring in the first place)!
  • Wear your eyeglasses or contacts regularly.  Even if you feel you can see relatively okay without them, they were prescribed to you for a reason.  Your glasses or contacts cannot help your eyes by just sitting in a case on your dresser.
  • Eat healthy, whole foods.  The benefits of good nutrition are extensive, and just as eating a large variety of fruits and vegetables and other whole foods while cutting out processed junk do wonders for your body’s health, so will it also positively affect the health of your eyes.
  • Wear sunglasses with UV protection.  Spring is in full bloom, and summer is on its way.  As you spend more time outside, it is as important to shield your eyes from harmful UV rays as it is to shield your skin from those rays with sunscreen.
  • If you smoke, drop the habit.  If you don’t smoke, don’t start.  Smoking has been linked to a higher risk of vision problems such as cataracts and macular degeneration.
  • Wash your hands often and avoid touching your eyes and face.  Not only will this help protect you from picking up colds or other illnesses as much, it will also help protect your eyes from eye infections such as conjunctivitis.
  • Wear eye protection while completing tasks that could harm your eyes, such as working in dangerous conditions, using a chainsaw, or riding a motorcycle, dirt bike, or ATV.  Not a whole lot will harm your eye’s health more than an object or accident injuring it and potentially blinding it temporarily or permanently.
  • Finally, be sure to take care of your own health physically, emotionally, mentally, and spiritually.  All of these tie in together, and when you are healthy and feeling good, it helps your eyes to be at their best health, as well!
