202. Ceguera nocturna
La ceguera nocturna, también llamada nictalopía, es una capacidad reducida para ver en oscuridad o con poca luz. Puede dificultar reconocer peatones, ciclistas, marcas viales, curvas u obstáculos de noche y durante el crepúsculo. Puede tener distintas causas, incluidas algunas enfermedades oculares, deficiencias vitamínicas o problemas de retina. Los conductores que tengan dificultades para ver con poca luz deben evitar conducir cuando su visión sea insuficiente y solicitar atención profesional de la vista.
What is night blindness?
Night blindness is difficulty seeing in darkness or low-light conditions, even when daytime vision may be relatively good.
Why is night blindness dangerous when driving?
It can make pedestrians, cyclists, road edges, signs and obstacles harder to detect, reducing the time available to react safely.
Is night blindness the same as being completely blind at night?
No. Night blindness usually means reduced vision in dim conditions, not a complete loss of sight.
What can cause night blindness?
Possible causes include retinal disorders, cataracts, certain inherited eye conditions and some nutritional deficiencies. An eye-care professional can determine the underlying cause.
Can glasses correct night blindness?
Glasses may help when poor low-light vision is partly caused by an uncorrected refractive error, but not every cause of night blindness can be corrected with glasses.
Should you drive at night if you have night blindness?
If your low-light vision is not sufficient for safe driving, you should avoid driving at night or in other dark conditions and seek medical advice.
