Selling Contact Lens Removal Gas

Hard contact lens

These contact lenses are classified as hard lenses due to the material used to manufacture them. Glass or polymer is often used to make these lenses. These lenses are more durable and more rigid than soft contact lenses. Hard contact lenses allow oxygen permeability and are not ‘hard’ for the eye.

Gas-permeable lens
Gas-permeable contact lenses are more rigid lenses but allow more oxygen to let your eye breathe. With proper care and regular cleansing you can wear gas-permeable lenses without getting them replaced except when your optician prescribe you not to continue wearing your old lenses. The only disadvantage which comes with the gas-permeable lenses is that they are less comfortable than the soft ones.
