Everyone should see their eye doctor at least once a year. It's important for people who wear glasses and contacts because your prescription can change over time, and regular eye doctor appointments will ensure you're always receiving the appropriate level of vision correction. Even people who don't wear contact lenses and glasses can benefit because their eye doctor also checks their eye health. Routine eye exams can detect diseases like glaucoma early, which can prevent blindness.
If you have cataracts, they will eventually obscure the vision in your eyes until you can no longer see as clearly. While cataracts can be a detriment in many ways, they are quite common as well and can be easily treated by a skilled optometrist or eye surgeon. Once cataracts are removed, you will be able to see more clearly, although total healing can take time.
When you get eye cataract surgery, you need to take care of your vision properly so the healing process can take place.
