Question 1

Accepted Answer

Yes: Retinis pigmentosa and similiar disorders can cause this.

Question 2

Accepted Answer

Fish, Vitamins: Recent studies have shown that eating fish (tuna, salmon) can decrease progression of age related macular degeneration by up to 40%.  Age related macular degeneration is the number one reason americans loose vision every year.  No symptoms occur, until it is very late.  Subtle physical signs occur many years prior the diagnosis such as drusen, dark clummping, and changes to the fovea.

Question 3

is it bad for your eyes to go back and forth from night vision to regular  vision quite quickly for maybe an hour period?

Accepted Answer

No problem: Eyes have wonderful neurological and chemical adaptation built in.  They will readily accomodate this change in light intensity and suffer no harm.

Question 4

often when i wake in the night, vision in one eye is much darker than the other. if i close the better eye, i can barely see in the dark. thoughts?

Accepted Answer

Rod cells: Night vision is control by the rod cells.  You may have weaker rod cells function in that side?  Or you may have cataract which filter outs light.  Its less likely you have cataract in your age unless you have history of trauma to that side , steroid use or smoking.

Question 5

is it possible to train my eyes to have night vision?

Accepted Answer

Maybe: Wearing slightly more (minus) myopic glasses improves the vision of many people at night because it corrects the myopic shift that occurs in darkness.

The longer you avoid light the better you can see night. Your vision gets better by the minute after you enter a dark room, this is called dark adaptation.

If you must see light (your phone) momentarily, keep one eye closed. Take multivitamins.

Question 6

my right eye low night vision help me please ?

Accepted Answer

Needs evaluation: Is the vision from the right eye poor at night compared to the left eye or does it simply not adapt to the dark well at night compared to the left eye?  Most likely is a need for eyeglass correction for that eye such as modest myopia.  It would be rare to have a unilateral dark adaptation problem  there are other possibilities which your ophthalmologist can sort out for you if persistent.

Question 7

poor night vision in one eye.what to do at 50?

Accepted Answer

Eye exam: It would be distinctly unusual for a person at age 50 to develop poor night vision in just one eye. Possible causes might include cataract, or retinal disease which is asymmetrical, i.e. Affecting one eye more than the other. Have an exam by an ophthalmologist asap.

Question 8

my right eye has really bad night vision help me plz?

Accepted Answer

Is this chronic?: If this is a longstanding condition (as far back as you can remember) it is likely permanent.  If it started recently (over the last few months or a few years) there may be a cause that can be treated.  I recommend having a dilated eye examination.

Question 9

i was wondering if there are any test to acquire night vision by eye surgeries? .

Accepted Answer

If : If your night vision has never been good--this may be genetic or it may be from undercorrected eye glasses or contacts.  Have your eye doc do a measurement in the dark to see if it is different than a "day time" measurement.

Question 10

i lost night vision completely in my right eye only. it gradually returned after 20-30 min. is this an emergency?

Accepted Answer

Yes: If you lost vision in one eye it could be a sign of a much more serious problem. You need to see a doctor right away for an evaluation. There are many possible causes of temporary loss of vision in one eye. Please do not delay. See a doctor today.
