Why do my eyes 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 I see so well in the dark
Rods are responsible for vision in dim or dark light. They are located on the outer edges of the retina and help with peripheral (side) vision. Rods don't provide color vision, so night vision is only in black and white. Rods are much more sensitive to light — 500 to 1,000 times more sensitive — than cones are.

Even a slight prescription for someone who may not need glasses during the day can make a significant improvement in night vision.

Why is my vision blurry in the dark

Why is my vision more blurry in the dark
Especially at night, you concentrate to see better and blink less. This causes even drier eyes and more blur. Refractive surgery. When the pupil dilates in dim light, it becomes larger than the area of the cornea treated in refractive surgery.
Can 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.
How do you fix light sensitive eyes
Avoid the use of fluorescent lighting at home. Try replacing any fluorescent lights with incandescent bulbs or warm white LEDs. Bring in as much natural light as you can, which is usually less problematic for people with photophobia. Install dimmers to control indoor lighting.

Will light sensitivity go away
This light sensitivity is often referred to as photophobia by medical professionals, and, for many, it can go away quickly. But for others, photophobia can be a persistent symptom of a diagnosed medical condition such as migraine, post-concussion syndrome or dry eye.
Can light sensitivity heal
In many cases, when the triggering factor is managed, then photophobia goes away. For example, your treatment plan might include: Medication Changes: If you are using a medication that causes a side effect of light sensitivity, then you can talk to your doctor about other treatment options.
