Do We Have a Dominant Eye?

Just like we use one side of our body more than the other and have a dominant hand that we use for writing, most of us also have a dominant eye.

A dominant eye isn’t always about one having better vision, but rather one leading better than the other because of preference. Your dominant eye is the one that provides slightly more input to the visual cortex of your brain and relays information more accurately, such as the location of objects.

Research shows that eye dominance and handedness are associated, though not directly related. Someone who is right-handed is more likely to be right-eye dominant, but it is possible to be right-handed and left-eye dominant.

Eye dominance can vary from person to person. One person may have strong degree of dominance in one eye, while another person may have an eye with a lesser difference in dominance from the other eye.

RAY-BAN WAYFARER: TIMELESS EYEWEAR

Bausch & Lomb, a U.S. eyeglass manufacturer, introduced the Ray-Ban sunglasses brand in the late 1930s. One of their designers invented the Wayfarer with all-plastic frames in the early 1950s.  Soon, the Wayfarer became the first sunglasses variety to meld style and functionality. All sunglasses do the same thing, but the Wayfarer made choosing shades a declaration of fashion consciousness. Bausch & Lomb sold the Ray-Ban brand to Italian eyewear manufacturer Luxottica in 1989. Since then, Ray-Ban has tweaked and reshaped the Wayfarer to suit modern tastes, but Ray-Ban hasn’t changed the Wayfarer’s essential fashion mission.   

The Wayfarer is essentially the standard plastic-framed sunglass shape. It has a horizontal bar that rests at the top of the nose, with rounded lens frames. The top corners of the frame fronts jut out a bit. They’re mostly flat in the front and do not curve to the contours of the face.  If you’ve seen the 1980s classic films “Risky Business” or “The Blues Brothers,” you’ve seen Wayfarers.

Cataract Surgery Can Benefit Those With Alzheimer’s Disease

As we age the natural lens in the middle of the eye will eventually become more cloudy, this is known as a cataract. With the cloudy discoloration present in a cataract, the eye’s natural lens begins to act like a filter causing a decrease in vision, contrast and the overall amount of light entering into the eye. In turn, everyday activities of daily living such as moving about the house, reading, and cooking can become more difficult. Studies have shown those with Alzheimer’s Disease also have difficulty perceiving contrast. Recently several studies have been released showing the benefits of cataract surgery for Alzheimer’s patients. Reports show with better vision comes better sleep patterns, less depression, and a better overall mood. Patients studied had mild dementia and at least one significant cataract. A neuropsychologist evaluated patients at their 1 month and 3 month post-operative visits. Mood, behavior, sleep patterns, the ability to function independently, and cognitive abilities were assessed. Results showed an overall increase in mood, recognition, ability to function independently, and sleep patterns. Dr Alan Lerner says, “If you can’t perceive something, it is hard to remember it.” A simple statement that is so true. The overall conclusion of the study showed that by improving the ability to perceive, cataract surgery can give an Alzheimer’s patient a better quality of life.
