Day blindness, or hemeralopia, is a visual condition that is the inability to see in bright light. It can also be described as insufficient adaptation to bright light. It is the exact opposite of nyctalopia (night blindness).
In hemeralopia, daytime vision gets worse, characterized by photoaversion (dislike/avoidance of light) rather than photophobia (eye discomfort/pain in light) which is typical of inflammations of the eye. In hemeralopia, the nighttime vision largely remains unchanged, hence many patients feel they see better at dusk than in the daytime.
This condition can occur at any age, but it is considered as more popular in the old because older adults have a greater risk of developing cataracts.
However, it can be managed by reducing your risk factors. Please discuss with your doctor for further information.
It is believed that signs and symptoms may vary on an individual basis for each patient. Symptoms include weak vision in light, difficulty seeing during driving, and slow vision adaption between bright and dim light conditions.
Early diagnosis and treatment can stop this condition from worsening and prevent another medical emergency, so talk to your doctor as soon as possible to prevent this serious condition.
If you have any signs or symptoms listed above or have any questions, please consulting with your doctor. Everyone’s body acts differently. It is always best to discuss with your doctor what is best for your situation.
Hemeralopia is known to occur in several eye conditions. It can also be caused by a rare genetic condition called Cohen Syndrome (aka Pepper Syndrome). Another cause of hemeralopia is brain injury.
In rare cases, it may develop complications such as hemeralopia, pigmentary chorioretinitis, optic atrophy or retinal/iris coloboma, leaving a serious effect on the person’s vision.

Depending on the current severity of your condition, your doctor will suggest some of treatment options below:
Genetic conditions that cause day blindness aren’t treatable. The genetic defect that causes pigment to build up in the retina doesn’t respond to corrective lenses or surgery.
To reduce the risks of day blindness, you should eat foods rich in antioxidant vitamins and minerals, which may help prevent cataracts. Also, choose foods that contain high levels of vitamin A to reduce your risk of day blindness. Certain orange-colored foods are excellent sources of vitamin A, including:
