Cataracts are extremely common, and almost everyone will eventually develop them over the course of life. A cataract occurs because of changes in the lens of the eye. Located just behind the pupil, this clear structure acts to focus light onto the retina at the back of the eye, so that objects can be seen clearly. A cataract occurs when the lens becomes cloudy, blocking the passage of light.

Fortunately, we don’t have to simply accept the...Read More

Myopia, commonly known as nearsightedness, is caused by an irregularity in the shape of the eyeball. The eyeball is elongated in a front-to-back direction. This causes light to be focused slightly in front of the retina, instead of directly on it. For people with myopia, objects up close can be seen clearly, but objects farther away will appear blurry.

For kids who have myopia, the condition generally gets...Read More

The eye’s natural lens is able to change shape in order to change focal distance, which allows you to go from looking at the horizon to looking at a book relatively quickly.
