3.  Contact lenses are thin lenses that sit on top
of the cornea .
 They correct refractive error just like
eyeglasses.

 As therapeutic lenses
 Occupational need

8. 1. Dry eyes
2. Redness
3. Any infection or lid abnormality
4. Previous history of infections or complains
problem.

11. 1. SOFT LENSES
 Highly water content > 70 %
 Ultra thin lenses< 55 mm
2. RGP LENSES
 Fluorosiliconepolymers–highDk
 Silicone–acryalatelenses
3. SILICONE HYDROGEL

14.  People with unpredictable or highly active
lifestyles.
 People with binocular vision abnormalities.
 People with high refractive error
 Convenience
 Less maintenance

15.  Increased risk of corneal infection
 Increased risk of inflammatory events
 Time costs
 Induced adverse effect
