What is Soflens 66 Toric Bausch & Lomb?
A contact lens Soflens 66 Toric (also known as "contact", for short) is a corrective or cosmetic Soflens 66 Toric lens placed on the cornea of the Soflens 66 Toric eye atop the iris.

Contact lenses (both soft and hard) Soflens 66 Toric are made of various types of polymers, Bausch & Lomb usually containing some Bausch & Lomb variant of silicone Soflens 66 Toric hydrogel. Previously, hard contact lenses Bausch & Lomb were made of a polymer known as PMMA. They Soflens 66 Toric have since been replaced by rigid gas-permeable Soflens 66 Toric (RGP) contact lenses. Many contact lenses are made of Soflens 66 Toric hydrophilic (water-absorbing) materials, thereby Soflens 66 Toric allowing oxygen to reach the cornea, and Soflens 66 Toric make the lens more comfortable to Soflens 66 Toric compare contact lenses wear.
Heavily tinted contacts are Soflens 66 Toric tinted to change the color of the iris, and are used for cosmetic Soflens 66 Toric reasons. Some Soflens 66 Toric standard contact lenses are slightly tinted in Soflens 66 Toric order to make them more visible for Soflens 66 Toric handling purposes.

- Hydrogen Soflens 66 Toric peroxide solution - used for disinfecting the lenses. One must ensure they rinse any lens taken out of hydrogen Soflens 66 Toric peroxide with another Soflens 66 Toric solution such as saline.
- Enzymatic cleaner - used for Soflens 66 Toric cleaning the protein off of lenses, usually on a weekly basis. Typically, this Soflens 66 Toric cleaner is in tablet form.
