What dry eye is
Dry eye is due to an insufficient amount or fast evaporation of the tear film. It is triggered by prolonged screen work (blinking less often), dry air, air conditioning, wind, some medicines and wearing contact lenses. The complaints are burning, irritation, redness and tired eyes.
Artificial tears and lubricants
The most commonly used are 'artificial tear' drops that moisten and soothe the eye surface; some contain hyaluronic acid for longer moisture retention, and for more marked complaints there are gels (e.g. with dexpanthenol) for the night. For frequent use, preservative-free products are preferred. Follow the product's instructions.
Habits that help
Frequent short breaks from the screen help (the '20-20-20' rule — every 20 minutes, look far away for 20 seconds), consciously blinking more often, humidifying the air and avoiding a direct stream from air conditioning or a fan. When wearing contact lenses, follow the recommended wear time and hygiene.
When to see a doctor
See an eye doctor for eye pain, light sensitivity, worsened or blurred vision, severe redness, purulent discharge, or if the complaints do not respond to artificial tears. These signs may point to a condition other than simple dry eye that needs examination.

Frequently asked questions
Which dry-eye drops should I choose?
For mild complaints, artificial tears often help; products with hyaluronic acid retain moisture longer, and gels are used for more marked dryness or overnight. For frequent use, preservative-free drops are preferred. If unsure, ask a pharmacist or eye doctor.
How often can I use artificial tears?
Artificial tears can usually be used several times a day as needed, and for frequent use, preservative-free products are preferred to avoid irritation. Follow the specific product's instructions, and if very frequent use is needed, consult an eye doctor.
Do screens cause dry eye?
Prolonged screen work reduces the blink rate and contributes to evaporation of the tear film, which often worsens the dry-eye feeling. Frequent breaks, conscious blinking and humidifying the air help. If the complaints persist, an examination is advisable.
Can contact lenses cause dryness?
Yes, wearing contact lenses can increase the dry-eye feeling, especially with long wear or in dry air. There are artificial tears suitable for lens wearers. Follow the recommended wear time and hygiene, and for persistent discomfort consult an eye specialist.
When is dry eye serious?
Ordinary dry eye is unpleasant but not dangerous. Concerning signs are pain, strong light sensitivity, worsened vision, severe redness or purulent discharge — they point to another condition and need examination by an eye doctor, not just artificial tears.
