It’s a type of CL that are more durable and resistant to deposit buildup, and generally give a clearer, crisper vision.
a. Soft contact lenses
b. Rigid gas permeable contact lenses
b. Rigid gas permeable contact lenses
It’s a type of CL that are are made of soft, flexible plastics that allow oxygen to pass through to the cornea.
a. Soft contact lenses
b. Rigid gas permeable contact lenses
a. Soft contact lenses
This type of CL has a is short adaptation time due to minimal movement and less tearing
a. Soft contact lenses
b. Rigid gas permeable contact lenses
a. Soft contact lenses
This type of CL is not as comfortable initially; and it may take a few weeks to get used to
a. Soft contact lenses
b. Rigid gas permeable contact lenses
b. Rigid gas permeable contact lenses
This type of CL has new materials that include silicone-hydrogels to provide more oxygen to your eye while you wear your lenses.
a. Soft contact lenses
b. Rigid gas permeable contact lenses
a. Soft contact lenses
