Soft Contact Lenses For Extended Wear

Most extended wear contact lenses are made out of silicone hydrogel – a material that combines the water-absorbing plastic of soft lenses with silicone. Adding silicone to the hydrogel plastic creates a lens that stays moist and allows more oxygen to transmit through the contact lens into the eye. This keeps the eyes healthier during contact lens use. The added benefit of more moisture and oxygen reaching the eye is why this material was added to extended wear contact lenses.

Any contact lens wearer who keeps their contacts in during the day and at night, or leaves lenses in for days at a time needs a contact that allows their eyes to breathe. The addition of silicone to the lens offers this functionality for optimal contact lens health.
