Wash hands with soap and water and allow to dry, advises Cooper Vision. Starting with the same eye as your dominant hand, scoop the lens out of the case with your index finger, and rinse it with contact lens solution. Be sure the lens is curved upward like a bowl; if it's not, it's inside out. Using your free hand, hold you eyelid open and insert the lens. Blink a few times to set the lens in place.Continue Reading
Toric contact lenses are used to correct vision in people with astigmatism, according to All About Vision. Most toric lenses are soft lenses made of either hydrogel or more breathable silicone hydrogel. There are also toric lenses made of rigid gas-permeable materials.
The main difference between toric lenses and conventional soft lenses is that regular contact lenses have the same power in all meridians across the lens, so if it rotates in the eye, there is no difference in vision. Toric lenses have different powers in different meridians, so they must remain in the same position in the eye, as noted by All About Vision. Thus, toric lenses are weighted at the bottom to keep them from rotating. Because of their more complex design, toric lenses are more expensive than traditional lenses.Learn more about Glasses & Contacts
