7 Common Reasons you may Have Poor Night Vision
The National Safety Council reports that your risk of a fatal crash increases threefold during dark hours.
Poor quality night vision is often the blame, and could be caused by one of the following:
Cataracts-A cataract is actually a cloudy film that often occurs over top of your eye’s lens. Typically attributed to aging, cataracts are more prominent in those over the age of 60.
Retinopathy-A common condition among diabetics, retinopathy can affect the blood vessels in your eye. It also makes it more difficult for you to adjust to the bright lights of oncoming traffic.
Glaucoma-This condition often affects peripheral vision. As a result, you may find it difficult to notice moving objects that are beside you, which can make changing lanes particularly dangerous.
Retinitis Pigmentosa (RP)-A genetic condition, RP causes cells within the retina to break down. This can affect night vision in particular, since the retina is largely responsible for transmitting light signals from the lens to your brain.
Fuch’s Dystrophy-With Fuch’s dystrophy, fluid may build up inside your cornea, causing swollen eyes and hazy vision. This condition tends to worsen as the day progresses, which is why it may cause more problems when driving at night.
Vitamin A Deficiency-If you have ever been blinded by someone suddenly turning on a light, this is a sign you have a Vitamin A deficiency. The same “shock” can happen when you experience bright lights shining in your eye while driving at night.
Fatigue-When your eyes are tired, you will automatically have more difficulty focusing. As such, you could experience night vision problems on occasion due to eye strain or even general fatigue.
