I went for Lasik Surgery in Singapore almost a year ago. My overall vision is almost perfect but I suffer from very bad night vision. As a result, I can't drive at night anymore. This is really affecting my life. I want to know if there's a cure for night vision, supplements to reduce it or if as a last resort, I should go for re-surgery again? Please advise.

The night vision that I'm getting is, everything light that I see when I drive or walk at night, is extra big, there are huge halos around any object with light. Also, it blurs nearby objects as a result.

If you are lucky, this is principally down to a small residual Rx, which is largely covered by your smaller pupils in the day-time (depth of focus or pinhole camera effect), so that you don't notice it then. If so, a pair of glasses with the missing minor correction could clear up your night vision considerably.

Otherwise, this is almost certainly a corneal issue, involving irregularity or loss of transparency. Persistent dry eyes might be another possibility, but you don't mention any discomfort.
In which case there is not going to be a pill or supplement to cure it.
It's going to take a very careful examination of the cornea (corneas? Is it equally apparent in each eye independently?) to see what the remedial possibilities are, if any.
I'm afraid halos (from mild to severe) are a known, though far from inevitable, adverse result of refractive surgery.

You should not go for re-surgery until the exact nature of the problem has been firmly diagnosed, and the risks and benefits of the treatment very clearly explained.

What does vitamin A have to do with vision?

The answer is complex, says Elias Reichel, M.D., assistant professor of ophthalmology at Tufts University School of Medicine in Boston. But it involves the part of the eye called the retina.

"The retina is that part of the eye that acts like the film in a camera," he explains. "It's used to perceive light." On the retina there are structures called rods and cones. These house four kinds of pigments, one of which binds to an eye-friendly form of vitamin A. When you enter a sunny room and light enters your eye, the pigment transforms. Instantly, the vitamin A in your eye changes shape and, in that process, excites nerve endings to start transmitting electrical impulses to your brain to let it know what's going on--that you've entered a sunny room.

When you enter a dark room, the vitamin A changes shape again and helps your eyes realize that you've entered a dark room.

But nothing is ever completely light or completely dark. That's why you have more than 130 million light- and dark-sensing eye structures that make the minute adjustments necessary to perceive light and dark. And they're all dependent on vitamin A to do their jobs.

Please explain, are you talking about blurred vision at night, glare, or things are too dark to see or?
