Pray: Zero, unless you live in an area of vitamin a deficiency- then eat some carrots or take vitamin a.

I agree with the answer in general. Some people feel that a light amber or yellow sunglass, so called "blue-blockers" make them see better for night driving. There is no conclusive data on this, but several patients of mine are true believers, and there is little downside risk.

A 48-year-old member asked:

Can you improve night vision or low light?

Sometimes: Decreased dim light vision is often caused by cataracts and other conditions that limit light getting to the receptors in the eye. Often, people with nearsightedness, farsightedness, astigmatism or presbyopia whose prescriptions have worsened will notice it most when in dim light. The most important first step to improving vision is an eye exam to determine the cause of decreased vision.

How can you improve your night vision?

Depends: For individuals with normal retinal function, there is, unfortunately, no way to develop superhero grade night vision. Conversely, for patients with decreased night vision or “nyctalopia”, as a result of dietary vitamin a deficiency, vitamin a supplementation will hopefully restore normal human grade night vision. Patients with degenerative conditions such as retinitis pigmentosa, unfortunately, lose night vision and peripheral vision from progressive photoreceptor loss. Patients with congenital stationary night blindness, cone/rod dystrophies and other degenerative disorders also have photoreceptor loss with loss of night vision. Although until now there hasn’t been much to offer these patients, research is currently underway investigating a large array of agents which may offer them some hope for the future.

Lasik - night vision.?

Some get glare: Some patients will notice glare or "haloes" around lights at night following lasik surgery. In the majority of cases, it is not severe and dissipates over several months following the procedure. Nearly all patients who have lasik are pleased that they did, although the displeased minority is very vocal in online communities. A prudent lasik surgeon will discuss these risks before the procedure.
