"Doc, My Night Vision is
Terrible"
This is one of the most common complaints
I hear from patients. People tend to have more problems seeing at night
because our straight ahead vision is designed for good light levels and
our peripheral vision is designed for black and white, dim light levels.
Generally, problems seeing at night are due to a combination of decreased
light and blurred vision. There are a number of things I tell patients
that may help them in the following categories:
Automobile; Make sure your headlights are clean and properly
adjusted by a mechanic, your windshield is clean, and lastly… try halogen,
high output headlamps. Install high output driving lights on your vehicle
and make sure they are adjusted correctly. Install high output driving
lights and have them professionally adjusted.
Eyeglasses and/or Contact lenses; Keep them clean, replace
scratched lenses or if they have a coating problem. Update your
prescription (when your prescription changes, most notice it first at
night). Try a good quality Anti-Reflective coating. You don’t wear an Rx?
Maybe you would benefit with one for night vision.
Night Myopia; Some patients experience changes in their
eye’s focusing where they become more nearsighted at night, giving them
decreased distance acuity than they test at daylight times. For those
patients, a slightly stronger Rx can be very helpful for night.
Contact lenses; Patients that wear Monovision contact lenses
will benefit from either wearing a pair of eyeglasses over their contacts,
that correct the reading eye for distance vision (2 eyes see better than
1) or by taking their reading contact lens out and inserting a distance
lens for that eye. ~RQ
