Frequently asked questions

Can I use tear drops as often as I need?

Generally yes — they are lubricants, not medicines. Choose preservative-free if using them often.

Will they cure dry eye?

They relieve symptoms but do not treat the cause. See an eye doctor if dryness persists.

What is the difference between drops and gel?

Gels are thicker and last longer but blur vision more, so they are often used at night.
