Cataracts can interfere with your ability to drive at night and see well enough to do your usual activities. When they disrupt your life or pose a safety issue, then it could be time to think about cataract surgery. Cataract surgery removes your clouded lens and replaces it with a new lens that can sometimes correct for vision problems you may have. At the very least, the surgery corrects your cloudy vision, and it may even allow you to see well enough that you won't need glasses.
You know that it's important to go to your primary care physician for an annual checkup. However, you might not realize that your eyes need routine checkups as well. If you wear contacts or glasses, you should visit the optometrist annually. If you don't need vision aids, you should still see the eye doctor every two years. If you've never been to an optometrist before, you may not know what to expect from the experience.
