Eye Examinations are more then just finding out if you can see 20/20. Monitor the health of your eyes, and compare it over time.

These are two statements that we hear daily from patients, and at first glance, they seem to represent opposite ends of the eye health spectrum. Unfortunately, its not so cut and dry, and both sets of eyes are at similar risk of having a sight threatening pathology, such as glaucoma. While achieving 20/20 or better vision is one of the goals of each eye exam, the other major goal of our examinations is devoted to either establishing an incredibly detailed and accurate baseline regarding eye health, or adding data points and creating a trend off of this baseline at annual follow-up exams. To achieve this, we utilize a substantial amount of imaging technology on every single patient.
Frequently patients ask me why their glasses’ lenses are thick on some edges and thin on the other, and I typically respond that because they have astigmatism their lenses have two types of curvature on each lens, just like the Calgary Saddledome. But that got me thinking, what if the Saddledome was a lens, what prescription would it have?
If a person with 20/20 vision hits a golf ball, how far along the ball’s flight path can they see and track the ball before it disappears?
It can be challenging to demonstrate to someone how you actually see without your glasses. You can’t just give them your glasses to try on since their eye will automatically try to clear them up (and possibly kick start a headache). But it turns out pretty much every smartphone has built in feature that does an excellent job in truly capturing how bad you see when your glasses are off.
Can an eagle see better than a hawk? How about an owl? And how much better can each see than the average human?
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.
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.
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?
What could be of enough importance in 1962 that if it was lost, a regular season NHL game would halt mid-play and the players would drop down on their hands and knees and look for it?
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?
