Difficulty seeing at night

Overview

Night blindness is a visual condition where a person has difficulty seeing clearly in low-light conditions or darkness. This symptom makes it challenging to navigate safely during nighttime or in dimly lit environments.

Common Causes

Night vision problems can occur naturally as we age, since our eyes produce less of the light-sensitive pigments needed for low-light vision. Vitamin A deficiency can also impair your ability to see in dim conditions, as this nutrient is essential for healthy retinal function. Spending long periods in bright environments or looking at screens can temporarily reduce your night vision adaptation, and certain medications like antihistamines may affect your eyes' ability to adjust to darkness.

Severity Levels

Mild: You may notice slight difficulty adjusting to darkness or need a bit more time for your eyes to adapt when moving from bright to dim lighting. Reading or driving at dusk might feel slightly more challenging than usual.

Moderate: You experience noticeable trouble seeing in low-light situations, making nighttime activities like driving or walking in poorly lit areas uncomfortable or unsafe. Your eyes may take much longer to adjust to darkness.

Severe: You have significant difficulty or inability to see in dim lighting or darkness, making nighttime navigation extremely challenging or dangerous. Even with adequate time, your vision may not improve enough to function safely in low-light conditions.

Medical Attention

Consult an eye care professional if you notice persistent problems with vision in dim lighting, as this could indicate underlying eye conditions that require treatment. Seek immediate medical attention if night vision difficulties are accompanied by severe eye pain, sudden vision changes, or complete vision loss. It's especially important to get evaluated if you're having trouble driving safely at night or if the condition is worsening over time.
