Doctor Shares Ways to Prevent Screen-Related Dry Eyes
Looking at a screen for a long time can make people blink less.
Blinking spreads tears over the eye, so fewer or incomplete blinks can let the tears dry faster.
This may make eyes feel itchy, gritty, red, or tired, and vision may sometimes blur.
The doctor says screens are not automatically harmful, but long stretches without breaks can bother the tear film.
Every 20 minutes, look at something about 20 feet away for 20 seconds.
Try to blink fully and keep the screen a little below eye level.
Air blowing straight at your face can also make tears evaporate faster.
Some people may benefit from lubricating eye drops, but frequent dryness or irritation should be discussed with an eye-care professional.
Prolonged screen use can reduce blinking or lead to incomplete blinks, making tears evaporate faster.
Dry-eye symptoms can include burning, redness, gritty sensations, watering, and fluctuating vision.
The ophthalmologist recommends looking about 20 feet away for 20 seconds every 20 minutes and blinking fully.
Keeping screens slightly below eye level and avoiding direct airflow toward the eyes may reduce tear evaporation.
Other suggested measures include adequate sleep and hydration, preservative-free artificial tears when needed, and good eyelid and contact-lens hygiene.

Quotes
Dr Ramya P
Ophthalmologist at Apollo Hospitals, Jayanagar, Bangalore
“Blinking is essential because every blink spreads a fresh layer of tears across the cornea and helps maintain a stable tear film. When blinking decreases, the tear film becomes unstable and evaporates more quickly, resulting in dryness and irritation.”
NDTV
“The key message is that screens are not inherently harmful to the eyes, but prolonged uninterrupted screen use can disturb the tear film and trigger or worsen dry-eye symptoms.”
