If your eyes feel gritty, burn or sting by the afternoon, you are not alone. Dry eye drops add moisture and ease that scratchy feeling. The right choice depends on what is causing the dryness. Preservative-free drops are the better pick if you use them several times a day, and thicker gels work better at night than thin liquids.
Our top pick is Systane Complete Preservative-Free, the drop most often recommended by people who use them. The other four picks cover a budget option, a preservative-free single-use choice, a drop built around electrolytes and a daytime option for contact lens wearers.

FAQ
Who each pick is for?
Systane Complete PF suits people who want a gentle, preservative-free drop for daily use. TheraTears Extra fits long workdays. Refresh Optive Mega-3 is worth a look if your eyes feel oily or evaporative. iVIZIA is the budget choice. Systane Ultra vials work for travel and post-procedure use.
What to look for?
- Preservative-free if you use drops more than four times a day, since preservatives can irritate the eye.
