Dificultad para ver de noche

15 May 2025

Difficulty seeing at night, also known as night blindness or nyctalopia, is a symptom that many people tend to normalize over time. However, it can be an indication of various conditions that affect visual health and, in some cases, require specialized medical attention.

Those who experience this problem often notice that at dusk, or in dimly lit spaces, they find it more difficult to distinguish objects, read signs, or drive safely. They may also experience a sensation of dazzling when faced with bright lights, such as other vehicles' headlights, and slower adaptation when moving from a bright to a dark environment.

Among the most common causes of this condition are uncorrected refractive errors, such as myopia, as well as retinal diseases such as retinitis pigmentosa or macular degeneration. It can also be related to developing cataracts, nutritional deficiencies—especially vitamin A—or certain systemic pathologies such as diabetes. Some medications can even affect night vision as a side effect.

It's important to note that difficulty seeing at night doesn't always appear suddenly. In many cases, it develops gradually, which can cause it to go unnoticed until it begins to significantly interfere with daily activities.

At any sign of decreased night vision, a complete ophthalmological evaluation is recommended. Detecting the cause early not only allows for effective treatment of the problem but also prevents potential major complications.
