The sun is so incredibly bright, that to safely view it, one would have to stack up at least 8 pairs (or more) of high-end sunglasses to meet the threshold deemed safe for the eyes. With the total solar eclipse crossing North America this year, now is a good time for a little reminder. NEVER LOOK DIRECTLY AT THE SUN.
There is an old joke about people living out in the prairies being able to watch their dog run away for days. Well if this is true (it isn't), then people living near the longest sightline on earth would be able to watch their dog run away for years.
Clean your furnace air ducts. Get teeth cleaned twice. Get approximately 10 haircuts. These are things that come at a modest annual expense that many of us do every year. Why? Because maintenance is a good form of prevention. So why then does the average person go 4 years between eye checkups?
We've all been told to avoid it, but is sitting too close to the TV actually bad for the eyes?
Fairly regularly at the end of an eye exam, a patient will say "Or maybe I should just eat more carrots?". I usually force a half-hearted laugh and a tepid agreement before explaining that Kale is actually what they should be consuming, and a little look back into life in WW2 Britain would explain where the carrot myth began.
Eyelid twitches are very annoying. And very common. The vast majority of them are completely benign, and harmless. The treatment of them is usually just reassurance and cutting down on stress, however there in an acedotal treamtnet that may work, although not clinically tested: quinine.
In 1750, legendary composer Johann Sebastian Bach was losing his eyesight. At the same time, a self-styled "healer" was "curing blindness" in flamboyant displays in town squares across Europe, to the delight of roaring crowds. They would eventually meet. What could go wrong?
Pinhole glasses operate on an optics principle that has been known for centuries. By decreasing the aperture size, the depth of field increases (i.e. the distance between the maximum and the minimum an object appears clear). It's the same reason people squint when they try to see better. So glasses based on this principle do work, but there are some drawbacks that keep them from being replacements to regular glasses, although in desperate situations they can be very handy.
At one time or another, we have all found ourselves quickly glancing up at a clock or a blinking light only to notice that it seems to briefly pause before resuming its normal rhythm again. How is this possible?
Eager job seekers and motivated employees are always trying to show how intelligent they are in hopes of landing a new job or scoring a coveted promotion. They try to talk smart, dress smart, act smart, and probably are smart, but it turns out one of the best validations of being smart might just be wearing their glasses (next to walking around with their IQ pinned to their name tag).
The eye chart showed the big 'E', and your child guessed it was a 'cat'. Either somebody needs to get the cat out of the exam room, or your little one may need glasses. What's the best plan of attack, not only to help now but to also help slow down the rate of degradation later on? After all, the number one fear I hear from patients is "I don't want to end up having glasses like Bubbles" ( I am not joking).
Everybody (I hope) knows UV light is harmful. But what many don't know is that it's slightly less energetic cousin is blue light, and more and more studies are showing that blue light exposure can lead to macular degeneration. Our TVs and digital screens are able to emit blue light, especially when the screen is showing blue images, such as the Jays uniforms. Increased duration of exposure increases the risk. Blue Jays games are routinly 3+ hrs. So, can watching the Jays be hazardous to your eyes?
