Wait, does that mean I'm farsighted or nearsighted?
Why do nearsighted people hold things very close to read? Why do farsighted people complain of eyestrain? Why do people need reading glasses as the get older?
Why Can't Humans See Reddish-Green?
Of all the things you've seen in your life, I promise you none of them were of the reddish-green colour. Nor were any of them of the blueish-yellow hue. Some scientists refer to these two colours as the forbidden colours. But why cant we see them?
The Zombie Parasite
Every so often I come across a patient who has vision loss as the result of a parasitic infection. The parasite in question is usually Toxoplasmosis gondii, and it can cause significant damage to the human retina. But that may not even be the most terrifying trait of the parasite that is nicknamed "The Zombie Parasite".
It is a really bad idea to look at the solar eclipse with whatever method you are trying to rig up.
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.
4 out of 5 people who are blind don't need to be
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?
Dont sit so close to the TV?
We've all been told to avoid it, but is sitting too close to the TV actually bad for the eyes?
The great carrot myth
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.
JS Bach, a quack and Cataracts.
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?
The Longest Second
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?
The Thicker the Glasses, the Smarter the Person?
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).
How to keep childhood myopia under control
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).
