How can you improve your night 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. ...Read more

Is it true that carrots help your night vision?

Depends: The basis for this "old wive's tale" is that, accurately, carrots as well as other yellow/orange vegetables and gourds (squash, pumpkin) are fantastic sources of vitamin a, an essential vitamin required for photoreceptor (cone/rod) metabolism. While severe vitamin a deficiency may lead to serious, but generally reversible, vision problems, such as night blindness, most people in developed countries meet more than their daily vitamin a requirements from normal diets and there is no need to consume exorbitant amounts of carrots. In fact, vitamin a excess may be toxic to the liver and some clinical studies have demonstrated that excess vitamin a metabolites may actually be potentially toxic to photoreceptors. ...Read more

Are there glasses that can increase your night vision?

Yes: In some patients adding a negative 1/2 diopter improves their night vision. Also night vision goggles can improve your vision at night. Spending several minutes in the dark, adapts your rods so you can see better. Use a red light flashlight to avoid loosing your dark adaptation. Don't forget that wild cats have 6 times better night vision than humans, so be careful out there. :). ...Read more

Poor night vision: do I have any options other than driver?

Poor night vision: do I have any options other than driver?

Corrective lenses: We all get more myopic (near-sighted) at night (stiles-crawford effect). Sometimes a stronger spectacle rx is needed for driving in the dark. There are retinal conditions that can cause poor night vision (search "nyctalopia"). A refraction performed with pupils dilated and ability to accommodate paralyzed can establish baseline spectacle rx, . In older people, a common cause is cataracts. ...Read more

I really need advice? Is there decreased night vision with age?

A little: Night perception requires the biochemical reconstitution of the light receptive pigments of the retina. As with all things, there is a little slowing of this with age. It is not usually very noticeable, so if this is a particular problem, see your ophthalmologist to see if there is another cause. ...Read more

Night Vision: There are two aspects to decreased night vision that have different causes. Some people experience blurred vision at night, such as difficulty reading road signs. This may be from a small glasses prescription that only shows up at night. Other people have trouble getting around in the dark, and the eyes adapt poorly to the dark. This may from retinal problems or nutritional deficiencies. ...Read more

Is it actually true that computer vision syndrome will ever go away?

Mostly: This is largely a condition due to eye dryness which occurs because of the offices in which computers exist. Computer work requires constant viewing at one distance which is tiring. Most who do this work for prolonged times are advised to wear the best eyeglass correction, have lubricating drops at hand for use, and take breaks over 1 1/2 hr. Looking off in the distance to rest your eyes. ...Read more
