Cannot see a thing without correction. Wore contacts off and on since 1958. I had Lasic done in 1998 and loved it. I chose monovision and I loved it. After doing my right eye for distance, the Dr. let me try a contact in the left eye to simulate the close vision. I could even read very fine print. A couple of years ago I had cataract surgery on both eyes and my vison changed. And I found as I get wiser (older) I need more light too.
