It’s
no surprise that most people don’t see well in the dark. However, some people
have considerable difficulty seeing at night or in poor light. This is
called “night blindness” or nyctalopia. Night blindness doesn’t
mean you are completely unable to see at night, but that your vision is poorer
then. It is not a disease in itself, but instead is a symptom of some other
type of vision problem. Certain cells in the eye’s retina are responsible for
allowing you to see in dim light. If these cells are affected by a disease or
condition, night blindness occurs.
Some
of the eye conditions that can cause night blindness include:
- Nearsightedness
- Glaucoma
- Certain
Glaucoma Medicine
- Cataracts
- Diabetes
- Retinitis Pigmentosa-an eye disease that causes blindness
- Vitamin A
Deficiency
- Keratoconus-an
cornea disease where it is very steeply curved
If
you or someone you know has difficulty seeing at night-especially if it seems
to be getting worse-pleas schedule an eye exam with eye doctors at Northwest Indiana
