In the United States, 40 million people use contact lenses to improve their vision. While most of these contact lens wearers adhere to the guidelines set out by their doctors, many do not. According to the American Optometric Association's annual American Eye-Q® survey, many people are putting their health and vision at risk by not following [...]
In a recent issue of the journal Optometry, researchers found that game-worn football faceshields are more susceptible to breaking when subjected to high-velocity impact than are new faceshields. For the test, high-velocity objects meant to simulate the force from a kick to the face were hurled at new and used polycarbonate faceshields. None of the [...]
One of the best parts of being an Optometrist is that humor is always infused into my day. Sometimes it's just what I need to break up my usual routine. Before I put eyedrops in a patient's eyes, I give them a tissue to wipe away any excess that may drip out of their eyes. Here are two funny stories related to eyedrops from the past few weeks.
I'm constantly amazed how each patient I see interprets their vision differently. Clarity that may be more than adequate for one person isn't even close to adequate for another. And aside from engineers, I never know how each person is going to react to asking "which is better, one or two?"
A brief history of the eye chart: the typical "Snellen Chart" is named after a Dutch Ophthalmologist who designed the chart in 1862 and is comprised of block letters. These letters have a standard and specific geometry, with each black line being the same thickness as each space within the letter, and the height being five times the size of each block. Originally, only the letters C, D, E, F, L, N, O, P, T, Z were used. These are the wall mounted charts that we see in all doctors offices, school nurse stations and and health clinics across America.
The Chicago Tribune (1/14, Stein) reports that "circle lenses," the contacts shaped like abnormally large eyes that have proven popular with teenage girls in Asia, are now "hitting American shores, where over-the-counter sales of nonprescription cosmetic contact lenses are illegal." The improperly fitting contacts have drawn scrutiny over fears that they "can cause short- or [...]
Transition lenses are clear doors and dark outside for clarity and comfort.
In a new study, researchers identified an unexpected biological pathway that appears to contribute to the development of glaucoma and its resulting vision loss. Prior research has suggested that the optic nerve head, the point where the cables that carry information from the eye to the brain first exit the eye, plays a role in [...]
HealthDay (12/27, Thompson) reported, "Cataracts are a leading cause of blindness among seniors in the United States, with more than half of all US residents developing the cloudy vision of cataracts by the time they reach 80 years old, according to Prevent Blindness America, a nonprofit group that focuses on eye health." According to eye [...]
The UK's Daily Mail (12/23) reported that, according to UK eye expert Sheraz Daya, "more patients who have been left blind after damage to their corneas could be helped with artificial eye implants." Daya "has called for patients whose sight has not improved through either transplants or stem cell treatment to be made eligible for [...]
