Clear answers to the questions our patients ask about vision, glasses, contact lenses and eye health.
Farsightedness is a focusing problem, not an eye disease. How to recognize it in children and adults, how it differs from presbyopia and how it is corrected.
Astigmatism is common and can usually be corrected well. Here's how to recognize it, why lights look streaky at night, and how to read the CYL and AXIS on your prescription.
Myopia makes distant objects look blurry. Here is what causes it, why it tends to increase during childhood, what research says about screens and outdoor time, and when to see an optometrist.
Each lens tint colour changes light in its own way, but none of them tells you whether your glasses block UV. Here is what each tint does, its limits behind the wheel and when to see an optometrist.
How long it takes to adjust to progressive lenses, and how to tell a fitting problem from a normal learning curve.
Transition lenses darken in the sun and clear up indoors. Here is what they do well, where they fall short in the car and in the cold, and how to tell if they suit you.
Blue light glasses are sold everywhere, but research has not shown that they reduce eye strain from screens. Here is what the studies and eye care organizations say, and what can help your eyes.
How to put in and take out your first contact lenses, how long it takes to get used to them, and which signs mean you should get your eyes checked right away.
