"It was the best of times, it was the worst of times." These famous words by Charles Dickens are playing out today in the area of technology.

We are living in the best of times when it comes to obtaining knowledge at the push of a button. But smartphones, laptops, video games, tablets, etc., can really increase our daily total screen time.

What are the symptoms of too much screen time for the eye, and how can you combat these symptoms?  Research shows that screen time can adversely affect your eyes, focus, moods, and ability to sleep and relax.

Doctors are also seeing an increase in dry eye syndrome because patients do not blink often enough while they are staring at the screen for a prolonged period of time. The lack of blinking can cause burning or watery eyes, rubbing of the eyes, and frequent headaches.

The key to combatting these symptoms is to consciously blink more, use rewetting eye drops, and take frequent breaks. Make it a priority to practice the 20-20-20 rule. For every […]

Do you have floaters in your vision?

Floaters are caused by thick areas in the gel-like fluid that fills the back cavity of your eye, called the vitreous.

Many people, especially highly near-sighted people, often see some degree of floaters for a good portion of their lives. Often, these floaters are in the periphery of your vision and may only be visible in certain lighting conditions. The most frequent conditions are when you are in bright sunlight and are looking toward the clear blue sky. I know this from personal experience since I have a floater in my left eye that I most often see when swimming outdoors. Every time I turn my head to the left to breathe I see this floater moving in my peripheral vision.

This is totally harmless other than when I’m swimming in the ocean and swear that sudden object in my peripheral vision is a shark bearing down on me. Some people who have floaters are not as lucky– the floater might be in their central vision and almost constantly […]

Eye doctors typically pride themselves on being able to improve someone’s vision through glasses or contact lens prescriptions. Whether it’s a first-time glasses wearer, or someone having either a small or large change in their prescription, we like to aim for that goal of 20/20 vision.

Despite our best efforts, however, correcting vision to 20/20 is not always a positive outcome for the patient. Whether someone will be able to tolerate their new prescription is based on something called neuroplasticity, which is what allows our brains to adapt to changes in our vision.

You or someone you know may have had this happen: Your vision is blurry, so you go to the eye doctor. The doctor gives you a new prescription, but when you get your new glasses, things seem “off.”

Common complaints are that the prescription feels too strong (or even too clear!) or that the wearer feels dizzy or faint. This is especially true with older patients who have had large changes in prescription, since neuroplasticity decreases with age. It is also more likely […]

Transition lenses in eyeglasses have been around for many years now. The mechanics behind transition lenses is that certain chemicals in the lens interact with UV light from the sun and turn the lenses dark when you go outside and back to clear when you go inside.

This is a great accompaniment to sunglasses, as it is not always convenient to be carrying around multiple pairs of glasses with you, especially when going from inside to outside frequently. However, there are some drawbacks to transitions, including the fact that they don’t get as dark as sunglasses, have some difficulty turning dark in the car, and have a tendency to keep a slight constant tint even in dark conditions.

Vistakon, the optical wing of Johnson & Johnson, came out with the first transition contact lens a few years ago.  They work well for some people, and don't seem to do a lot for others.

Just a couple personal thoughts: It can look a little strange, depending on the person and the eye color. The material itself turns […]

For over 40 years the standard surgical treatment for glaucoma was a procedure called a trabeculectomy.

In a trabeculectomy, the ophthalmic surgeon would make a hole in the wall of eye to allow fluid from the inside of the eye to flow out of the eye and then get resorbed by the blood vessels in the conjunctiva (the mucous membrane that covers the white part of the eye).

This surgery often resulted in a large decrease in the Intraocular Pressure (IOP). Reducing the IOP is the goal of glaucoma surgery because multiple studies show that if you can reduce the pressure the progression of glaucoma slows.

The problem with trabeculectomy is that although it frequently lowers the pressure, it also has a fairly high complication and/or failure rate. This led to some reluctance to perform the procedure unless the glaucoma was severe, or the pressure was very high. As a result of those issues there has been a search during the last 40 years for something that had a lower complication rate and could be more […]

If it's been a while since your last eye exam–or if you've never had one done–it's always nice to know what testing you might have done and what issues the eye doctor looks for.  Here's the scoop on some common testing…

Visual Field

The visual field test is designed to check your peripheral vision, which isyour ability to see things where you are not directly looking.

When we test your vision on the basic eye chart, we are testing how well you see right in the center and it gives us no idea if you can see out away from the center. Your peripheral vision is very important because it gives you the ability to move around your environment without running into things.

There are several diseases that can severely impact your peripheral vision while leaving central vision unaffected. Some people can have perfectly normal 20/20 central visual acuity and have almost complete loss of their peripheral vision.

The main culprits that can have a big impact on your peripheral vision are glaucoma, some retinal diseases […]

Lyme disease is an infection that is caused by a spirochete (a type of microorganism) called Borrelia burgdorferi, and more rarely by Borrelia mayonii. It is transmitted to humans by the bite of a deer tick.

The disease has a strong geographical incidence, being highly concentrated in the Northeastern United States and also in Minnesota and Wisconsin.  However, the tick's habitat has been spreading rapidly, and it is always a good idea to be cautious and consult medical help if you think you might have been bitten by a tick that could possibly be infected.

Lyme disease was first recognizedin the area of Lyme, Connecticut, in 1975. It can start with a characteristic “bull’s eye” rash, in which there is a central spot that is surrounded by clear skin that is then ringed by an expanding rash. It can also appear just as an expanding rash.

This rash usually starts within days of the tick bite. Eye problems can occur along with this rash in the first phase of the disease. This […]

A common question asked during the eye exam is, “When is the puff coming?”  

Patients are referring to air-puff or non-contact tonometry. Tonometry is the procedure used to measure eye pressure, and this is important for diagnosing and monitoring glaucoma.

In non-contact tonometry, a puff of air is used to measure the pressure inside the eye.  The benefit of this test is there is no actual contact with the eye, but the air puff is sometimes very startling for patients. Some people hate that test and it isn’t the most accurate way to measure your eye pressure.

Some doctors don’t even use the air-puff test. Instead, they place a yellow drop that consists of a numbing medicine and then shine a blue light on the eye. This is done in front of the slit lamp and a small tip gently touches the eye to measure the eye pressure. This procedure is called Goldmann tonometry and is considered the gold standard for measuring eye pressure.  

Another method for checking eye pressure is the Tonopen. This […]

The retina is the nerve tissue that lines the inside back wall of your eye. Light travels through the pupil and lens and is focused on the retina, where it is converted into a neural impulse and transmitted to the brain. If there is a break in the retina, fluid can track underneath the retina and separate it from the eye wall. Depending on the location and degree of retinal detachment, there can be very serious vision loss.

Symptoms

The three 3 F’s are the most common symptoms of a retinal detachment:

• Flashes: Flashing lights that are usually seen in peripheral (side) vision.

• Floaters: Hundreds of dark spots that persist in the center of vision.

• Field cut: Curtain or shadow that usually starts in peripheral vision that may move to involve the center of vision.

Causes

Retinal detachments can be broadly divided into three categories depending on the cause of the detachment:

Rhegmatogenous retinal detachments: Rhegmatogenous means “arising from a rupture,” so these detachments are due to a break in the […]

We sometimes get asked, "Why do I need an eye exam when I can see great?"

An eye exam doesn't just check your visual acuity–we are also looking for a number of treatable eye diseases that have few or no visual symptoms in their early stages. In fact, the three leading causes of legal blindness in the United States all start with almost no visual symptoms detectable by the person wit the disease. The three diseases are macular degeneration, glaucoma, and diabetic retinopathy. Each of these diseases gets more prevalent as people age. That is why regular eye exams are recommended to become more frequent as adults get older.

Macular Degeneration: The leading cause of legal blindness in the United States is a treatable–but not curable–disease. Early detection and treatment can significantly improve the long-term outcome. In the earliest stages, often when people are unaware that they have a problem, treating the disease with a very specific vitamin regimen called AREDS 2 can help. These vitamins have been shown to slow the progression of the disease and […]
