Okay, a cataract is basically a clouding of your eye (well the lens in your eye). There are no concreate explanations for how cataracts come about, but some studies have shown that smokers are twice as likely to develop cataracts!

Now before you jump in and go get your cataracts operated on, realize that a change in your glasses (or contacts) perscription can delay the need for cataract eye surgery.

But if your cloudy vision is starting to impact your daily life, then by all means go talk with your doctor about surgery.

Eye surgery to fix cataracts is one of the most successful operations around these days : 98% of people have better vision after the surgery.

I hope this helps answer your questions about eye surgery to correct your cataracts.

Have a super day!
