Is there anything that will make my night vision better?


Difficulty seeing clearly at night is a common problem everyone will experience to some degree when available light is in limited supply. This is especially true as you get older because the eyes become slower at adjusting to changing light conditions. This can be an issue when driving, as the eyes will soak up the light from headlights and other sources quickly, but find it difficult to switch back to environments where the light is dim.

If driving is becoming an issue, you should visit your optometrist for an eye exam as you may require glasses or contact lenses when behind the wheel. You may also be advised to invest in an antireflective coating on your lenses to reduce glare from oncoming headlights. Cleaning dirt from your glasses and windshield can also help, as grime can scatter the available light and encourage glare. My night vision is noticeably worse, what could it be? While many people's night vision will get worse as they age, there are a number of reasons why it could deteriorate rapidly and severely, such as:

Vitamin deficiency

Vitamin A is known to improve vision and is available in carrots and green leafy vegetables. Lack of zinc: Like vitamin A, zinc is useful for maintaining eye health. It is common in beef, poultry and beans, although deficiencies are rare in developed countries.


A common eye complaint as you age, cataracts often cause night vision problems. They can be removed surgically.


If you have diabetes, high blood sugar can damage the eye over time, resulting in poor vision in dim light.

Laser eye surgery complications

It is possible, but rare, that you develop night vision issues after having laser eye surgery. Sunlight exposure: Temporary problems with night vision can be caused by exposure to UV rays, so make sure to wear sunglasses in sunny weather.
