Silicone Hydrogel Contact Lenses

Have you heard of Silicone Hydrogel Contact Lenses?
Silicone Hydrogel contact lenses are made of a high oxygen permeable material that allows more oxygen to flow into the cornea compared to conventional contact lenses, and are described as 100% more comfortable. Within the next few years, more patients will be wearing silicone hydrogel lenses over any other lens material.

What are the benefits of Silicone Hydrogel Contact Lenses to a contact lens wearer?
Silicone hydrogel contact lenses help minimize problems like redness, dryness, swelling of the cornea and corneal infections. Silicone hydrogel lenses allow more oxygen to the cornea which results in better eye health. This results in much improved comfort levels.

Other advantages of silicone hydrogel lenses include more resistance to protein deposits, less drying of the lenses, lower risk of eye infection, easier handling due to increased rigidity of material.

These lenses are especially useful in the following types of patients:

– Young wearers who tend to ‘over-wear’ their lenses
– People who tend to nap in their lenses
– People who wear their lenses for more than 12 to 14 hours a day
– People who work for a long duration of time in central heating or air conditioned rooms
– People who experience end of day discomfort, dryness, or redness
