The answer is quite simple. The time to have your cataract removed is when you believe your quality of life would be better if you could see better. Many patients with cataracts describe increasing glare, especially at night, and blurry vision most noticeable during activities such as reading and driving. If you feel your vision is not as clear as it once was, you should have a complete eye examination to determine if a cataract is causing your visual changes. Only you can decide when it's time to open your eyes to a brighter, clearer world.
