How to Adjust Toric Contact Lenses
Toric contact lenses are prescription contact lenses designed for people with astigmatism, an irregularly shaped cornea or lens. Toric lenses are available for both nearsightedness and farsightedness, and come in soft or rigid gas permeable (RGP) forms. They are generally weighted at the bottom to prevent rotation, since the lenses have two powers to compensate for the astigmatism. To ensure a comfortable fit, you need to make sure that your toric contact lenses are customized for the shape of your eyes.Instructions

Make an appointment with your optometrist and make sure that he correctly diagnoses your astigmatism. Request toric contact lenses as some optometrists may suggest that you try standard contact lenses first because they generally cost less and are more readily available.

Decide whether to use soft toric lenses or rigid gas permeable toric lenses. Soft lenses are easier to adjust to, but RGP lenses tend to hold their shape better, which often results in crisper vision. RGP lenses are also less expensive since they do not require the same special materials and production methods as soft lenses.

Get a proper fitting for your toric contact lenses. Your optometrist should take measurements of your eyes to make sure that the right sized contact lenses are ordered. You will be given a trial pair to wear.

Wear and care for your toric lenses as instructed. Always wash your hands before handling your toric lenses, and soak them in an appropriate solution overnight. Don't sleep or go swimming in your contacts. If you feel any irritation from your lenses, immediately remove them and contact your optometrist.
