Night Blindness: Age Groups at Risk & Causes

The age groups most commonly affected by nyctalopia, also known as night blindness, are:

1. Older Adults: As people age, their production of rhodopsin, a pigment essential for night vision, decreases. This can lead to difficulty seeing in low-light conditions.

2. Children and Adolescents: While less common, nyctalopia can affect children and adolescents, particularly those with certain medical conditions, such as vitamin A deficiency or retinitis pigmentosa.

3. People with Certain Eye Conditions: Certain eye conditions, such as cataracts, glaucoma, and macular degeneration, can also cause nyctalopia.

4. People with Diabetes: Diabetes can damage the blood vessels in the retina, leading to night vision problems.

5. People with Nearsightedness: Nearsighted individuals (myopia) may experience more difficulty seeing at night due to the shape of their eyes.
