What Causes Low Vision?

In a perfect world, low vision would have one cause and that cause could be remedied, restoring full vision. But low vision isn’t a single condition—and it can have multiple causes In most cases, low vision in Wilmington, NC develops gradually, but your optometrist can help diagnose why it’s happening.

Eye Disease

One of the most common causes is age-related eye disease. Conditions like macular degeneration, glaucoma, and diabetic eye disease change how the eye processes visual information over time. These conditions don’t usually cause sudden vision loss. Instead, vision slowly becomes less reliable, making tasks like reading, recognizing faces, or driving more difficult.

Underlying Conditions

Low vision can also be linked to problems beyond the eye itself. The optic nerve and brain play a major role in how we see. Strokes, head injuries, or neurological conditions can interfere with how visual signals travel from the eye to the brain. When that communication is disrupted, vision may be reduced even if the eyes themselves appear healthy.

Genetics

Some people experience low vision because of inherited or early-onset conditions. These may affect retinal function or how the eye develops. Vision loss from these causes often begins earlier in life and may change gradually rather than all at once.

Eye Injury

In other situations, low vision develops after injury, infection, or inflammation inside the eye. Severe trauma or untreated eye disease can permanently affect visual function, especially if care is delayed.

Because low vision has many possible causes, diagnosis is essential. A comprehensive eye exam helps identify what’s contributing to vision loss and whether treatment, monitoring, or supportive care is appropriate.

Low vision doesn’t happen for just one reason. Understanding the underlying cause allows patients and optometrists in Wilmington, NC to focus on protecting remaining vision and improving daily visual function wherever possible.
