Kudret Eye İstanbul Chief Physician Op. Dr. Nail Sönmez explains the risks and gives practical tips for protecting the eyes in winter.

## Quick Facts
- **Most common winter problem:** Conjunctivitis (viral, bacterial, allergic, dry eye related)
- **Snow risk:** Reflected UV can burn the cornea (snow blindness)
- **Sunglasses:** Needed in winter too; should block 99% to 100% of UVA and UVB rays

## Winter Eye Infections
- Viruses and bacteria behind colds, flu and tonsillitis can easily infect the eyes and cause conjunctivitis.
- Allergic conjunctivitis can be triggered by winter air pollution, house dust mites, mould fungi and more time spent indoors.
- Dry eye: wind, moisture loss from indoor heating and dry air damage the eyes.
- Conjunctivitis symptoms: watering, discharge, crusting, redness, itching, stinging, swelling. See an ophthalmologist as soon as possible; treatment depends on the type and course.

## Snow and Sunlight
- Lower temperatures do not reduce the effect of the sun's harmful rays; snow reflects ultraviolet rays.
- Outdoor workers, people playing in snow and snow sports enthusiasts should be careful; skiers should wear protective goggles.
- Reflected rays can burn the cornea (snow blindness); intense sunlight exposure invites pterygium and cataract.

## Tips for Winter Eye Health
Low body resistance, lower serotonin and more stress in dark winter weather raise the risk of disease.
- Wash hands frequently; avoid touching, rubbing or scratching the eyes.
- Use disposable paper tissues during colds and flu and never reuse them.
- Prefer paper towels; do not share towels; if using cotton towels, keep separate hand, face and eye towels.
- Humidify home and workplace air (for example water on the radiator or in a container).
- Contact lenses and long computer use worsen dry eye; a doctor can prescribe suitable drops.
- Wear sunglasses blocking 99% to 100% of UVA and UVB; skiers and snow workers need glasses that protect from the sides, above and below.
- Do not rely on hearsay; consult a specialist for any eye complaint.
