When Your Eyes Ask for Help
Burning, dryness, redness, itching: these are the most common signals our eyes send us when something is wrong. In many cases, the solution is within reach — literally — with the right eye drops. But among the dozens of products available in pharmacies and online, how do you choose the most suitable one for your needs? This guide will help you.
The main types of eye drops
Artificial tears — for dry eyes
These are the most widely used eye drops. They replicate the composition of the natural tear film and hydrate the ocular surface. Ideal for those suffering from chronic dry eye, for contact lens wearers, or for those who spend many hours in front of screens. Available in formulations with or without preservatives — for frequent use, preservative-free single-dose options are preferred.
Antihistamine eye drops — for allergies
Contain antihistamine active ingredients that block the allergic response at the ocular level. Indicated for seasonal allergic conjunctivitis (pollen, dust mites) or perennial allergies. They quickly reduce itching, watery eyes, and redness due to allergies.
Decongestant eye drops — for redness
They act on the blood vessels of the conjunctiva, quickly reducing redness. Warning: they should not be used for more than 3-5 consecutive days to avoid the rebound effect (return of redness).
Hyaluronic acid-based lubricating eye drops
Hyaluronic acid is a natural humectant with a high water retention capacity. Hyaluronic acid eye drops offer more lasting lubrication than simple artificial tears and are particularly indicated for moderate-to-severe dry eye.
Antibiotic and antiviral eye drops
These are prescription-only medications, indicated for bacterial or viral eye infections (infectious conjunctivitis, keratitis). They should never be used without medical indication.
How to choose the right eye drops
- Mild dry eye: preservative-free single-dose artificial tears
- Moderate-to-severe dry eye: high-concentration hyaluronic acid eye drops
- Seasonal allergy: antihistamine eye drops (consult your doctor or pharmacist)
- Occasional redness: decongestant eye drops, max 3-5 days
- Use with contact lenses: only specific contact lens compatible eye drops
Beware of preservatives
Many eye drops contain benzalkonium chloride (BAK) as a preservative. If used frequently, it can irritate the ocular surface and worsen dry eye symptoms. For daily and prolonged use, always choose preservative-free or single-dose formulations.

Frequently asked questions about eye drops
Can I use eye drops with contact lenses?
It depends on the type of eye drops. Artificial tears compatible with contact lenses are specifically formulated to be used while wearing lenses. Decongestant and antihistamine eye drops, however, should be applied with lenses removed, waiting at least 15 minutes before reinserting them.
How long can I use an opened eye drop bottle?
Multi-dose eye drops, once opened, should generally be used within 30 days. Single-dose vials should be used immediately after opening and not stored. Always check the expiration date and product instructions.
Can eye drops worsen dry eye?
Yes, if they contain preservatives like BAK and are used frequently. For this reason, for chronic dry eye, preservative-free or single-dose formulations are always recommended.
What is the difference between eye drops and artificial tears?
Artificial tears are a specific type of eye drop, formulated to hydrate and lubricate the ocular surface by replicating the composition of the natural tear film. The term "eye drops" is more generic and also includes products with pharmacological active ingredients (antihistamines, antibiotics, decongestants).
