Are you having trouble seeing at night? You could be suffering from night blindness.
What is night blindness? Night blindness, or nyctalopia, is having difficulties seeing at night or in dim lighting situations. There are a number of underlying causes that can be the culprit. Treatment requires your Victoria optometrist to determine the cause. Here are some of the common conditions::
Cataracts – a clouding of the natural lens of the eye causing loss of vision
Nearsightedness (myopia) – some that suffer from myopia can have issues with impaired night vision
Retinitis Pigmentosa – this is a genetic condition in which the pigmented cells in the retina break down causing a loss of peripheral vision and night blindness.. The patient ends up with extremely poor night and general vision. There is currently no treatment but rather low vision training for the patient.
Eye Surgery – – procedures such as LASIK can result in reduced night vision and glare as either a temporary or permanent side effect.
Vitamin A Deficiency – vitamin A, or retinol, is found in greens (kale, spinach, collards, broccoli etc.), eggs, liver, orange vegetables (carrots, sweet potatoes, etc.), and butter. This can cause nighttime visual impairment. Your doctor may prescribe Vitamin A supplements if you have a serious deficiency.
Injury – an injury to the eye or the part of the brain that processes vision can result in reduced night vision.
Eyewear Problems – scratched glasses lenses or damaged lens coatings can also cause trouble seeing at night even if your vision correction is accurate. A quick an easy fix: a beautiful new pair of glasses!
How Can You Treat Night Blindness?
Some conditions above are treatable, while others are not. The first step is to book a comprehensive eye exam so we can determine what the underlying cause is. Treatments range from simply purchasing a special pair of glasses, lens coatings or contact lenses to wear at night to surgery and medication.
The key is to have an eye exam as soon as you begin to experience any changes in your vision. Anything that is not normal for your eyes needs to be checked immediately.
