Why is eyesight worse in the dark
As the light dims, your pupils dilate (grow larger) to take in more light. However, a dilated pupil reduces your ability to change your focus between near and far objects, so that, for instance, while driving you may be “blinded” by streetlights and oncoming headlights.
Why can I see better in the dark
Rhodopsin is the photopigment used by the rods and is the key to night vision. Intense light causes these pigments to decompose reducing sensitivity to dim light. Darkness causes the molecules to regenerate in a process called “dark adaptation” in which the eye adjusts to see in the low lighting conditions.
Why can some people see better at night
Light-eyed people (with blue or green eyes) have slightly better night vision because they have less pigment in the iris, which which leaves the iris more translucent and lets more light into the eye.
What affects eyesight
The leading causes of blindness and low vision in the United States are primarily age-related eye diseases such as age-related macular degeneration, cataract, diabetic retinopathy, and glaucoma. Other common eye disorders include amblyopia and strabismus.
Why is my vision better in light
When intense light rays reach your eye, the iris responds by constricting the pupil, thus protecting the retina and helping it process the incoming image better. The opposite occurs in low light when the iris dilates the pupil to allow as much light in as possible.
Do lighter eyes see better in the dark
While blue eyes are more sensitive to light during the day, people with blue eyes tend to see better at night – unless there are bright lights. In that case, the lack of melanin makes them as sensitive to light at night as they are during the day.
Do darker eyes see better
Those with darker colored eyes experience less visual discomfort in bright, sunny conditions. Also, darker irises reflect less light within the eye, reducing susceptibility to glare and improving contrast discernment—so people with darker eyes may have better vision in high-glare situations, such as driving at night.

What is the rarest eyes
Green irises (the rarest eye color) have less melanin than brown eyes but more than blue eyes, for instance. “Brown is on one end, blue on the other, and hazel and green are in between,” Dr. Patel says. This also means that brown is dominant and blue is the least dominant, also known as recessive.
What weakens eyesight
Some of the most common causes of low vision include age-related macular degeneration, diabetes and glaucoma. Low vision may also result from cancer of the eye, albinism, brain injury or inherited disorders of the eye including retinitis pigmentosa.
