Why does my eye sight worsen at night?!


Question: Why does my eye sight worsen at night?
I have horrible eye sight. I have to wear contacts or glasses all of the time to see even an inch in front of my face. When I wear my contacts, and drive, I am fine. At night, however, I can barely see anything at all when I drive. I always wear my contacts, so I don't understand why I can see perfectly fine on the road during the day, but not at night. At night I have to squint my eyes and really concentrate. Does anyone know why this might be?

Answers:

this is a SUPER COMMON complaint, and usually its from an optical phenomenon called "spherical aberration". the short version is: large aperture = bad vision.

when you're in the dark & your pupil is big, most nearsighted people see worse.

There's less light during the night which makes it harder for us to see. Also, if you've been in a well lit area for quite a while and suddenly look into somewhere dark, your eyes will take a while to adjust to the sudden change.



Your eyes have something called rods and cones. One is for seeing during the day and one is for seeing at night. I'm not sure which is which. You might try talking to an eye doctor for a solution. Some people naturally have one stronger than the other.



Because it's dark.

At night less light reaches your eyes so you can't see as far. The pupils dilate at night but if you use contacts this might not be enough.

You should see your optician about this, perhaps get driving or night glasses



I agree with Princeidoc, i would only add that your vision should be a little bad at night, not like you describe, if it is that bad at night you should check your precription



Nothing abnormal, it is because you are tired. I have the same problem. Just in case, though, ask your eye doctor.
