What visual impairment may stem from prolonged use of digital screens?

• A. Night blindness
• B. Cataracts
• C. Digital eye strain
• D. Glaucoma

Answer: (C)

The correct answer, digital eye strain, accurately reflects the visual impairment commonly associated with prolonged use of digital screens. This condition, also known as computer vision syndrome, includes symptoms such as eye fatigue, dryness, blurred vision, and headaches, which arise from extended periods of focusing on screens without breaks.

The primary factors contributing to digital eye strain include screen glare, inadequate lighting, improper viewing distances, and the reduced blinking rate that frequently occurs during screen usage. Recognizing and addressing these symptoms is important, especially in today's technology-driven environment where screen time can be significant.

In contrast, night blindness relates to difficulties seeing in low-light conditions and does not have a direct connection to screen usage. Cataracts and glaucoma are serious eye conditions but are not specifically linked to screen time. Cataracts involve clouding of the lens of the eye, while glaucoma is associated with increased intraocular pressure and damage to the optic nerve; both develop due to age-related factors or other health issues rather than directly from digital screen exposure.
