What are the Most Powerful Refresh Eye Drops?

There are many different subtypes of Refresh eye drops. Most of them are different types of artificial tears. Only two of them actually contain medication: Refresh Eye Itch Relief and Refresh Redness Relief.

Refresh Tears

• Artificial tear eye drops do not contain any medication. They all contain a moisturizing agent and a viscosity agent. Some of them contain a preservative. The power of an artificial tear drop is generally measured by its viscosity.

Viscosity

• Viscosity describes how thick a liquid is. The higher the viscosity of the artificial tear, the longer it will stay in the eyes after it is instilled. Therefore, the more severe the dry eyes, the higher the viscosity that is required. The Refresh brands with the highest viscosity are the ones that are the strongest.
