BUt seriously, the betacarotene in carrots is good for your eyes so they may well improve your night vision

Background: Rod cells in the eye can perceive black and white images and work best in low light. Rhodopsin is a chemical found in the rods. Rhodopsin is the key to night vision, it is the chemical that the rods use to absorb photons and perceive light. When a molecule of rhodopsin absorbs a photon, it splits into a retinal and an opsin molecule. These molecules later recombine naturally back into rhodopsin at a fixed rate, and recombination is fairly slow. So, when you expose your eyes to bright light, all of the rhodopsin breaks down into retinal and opsin. If you then turn out the lights and try to see in the dark, you can't. The cones (color perception) need a lot of light, so they are useless, and there is no rhodopsin now so the rods are useless, too. Over the course of several minutes, however, the retinal and opsin recombine back into rhodopsin, and you can see again. This explains why the eyes need several minutes to adjust to the dark.

Answer--> Carrots are a good source of Vitamin A. The retinal used in the eye is derived from vitamin A. If a person's diet is low in vitamin A, there is not enough retinal in the rods and therefore not enough rhodopsin. People who lack vitamin A consequently may suffer from night blindness. So, whatever means you use to get sufficient vitamin A (ie RDA) will help your night vision be it from carrots, spinach, sweet potato or any other source.

Yes. The vitamin A in carrots is a precursor to the pigment used by the rod cells in your eyes to detect incoming photons. An inadequate supply of vitamin A will decrease your night vision ability.

Don't overdo the carrots, though.

Carrots are an excellent source of antioxidant compounds, and the richest vegetable source of the pro-vitamin A carotenes. Carrots' antioxidant compounds help protect against cardiovascular disease and cancer and also promote good vision, especially night vision.

Beta-carotene helps to protect vision, especially night vision. After beta-carotene is converted to vitamin A in the liver, it travels to the retina where it is transformed into rhodopsin--a purple pigment that is necessary for night-vision. Plus beta-carotene's powerful antioxidant actions help provide protection against macular degeneration and the development of senile cataracts--the leading cause of blindness in the elderly.

I know for sure that if your eyes are weak and hurt,& you eat carrots raw,it strengthens your eyes definitely and makes you feel like 'healthy eyes!' so if your eyes are healthy & strong then I believe you should be able to see better in the dark.God bless you.

Yes, purchase one pair of night vision goggles and eat two carrots, you will see at night if you wear the goggles properly.

No, they don't help you see specifically in the dark.
Carrots contain Vitamin A, a deficiency of which can cause vision problems, both in the light and the dark.
