Toric Contact Lenses for Astigmatism

Astigmatism is a condition that is brought on by an irregular shape of the cornea– the clear part of the eye that covers the iris and the student. The cornea is normally smooth, round, and spherical however in an astigmatic eye, the cornea becomes a shape that is not spherical and develops a second curve. Among the primary duties of the cornea is to focus light onto the retina which allows you to see plainly. When the cornea is out of shape and develops two curves, this produces two centerpieces for that reason causing blurred vision.

The irregular shape of the eye makes it hard for conventional contact lenses to fit and provide clear vision and therefore requires customized contact lenses such as toric lenses or stiff gas permeable lenses (RGPs).

Toric contact lenses are likewise designed in such a method that the lenses remain in put on the eye to keep the correct vision. Often as the eye moves or blinks the lens can rotate significantly on the eye. If this rotation continues with a soft toric lens, a stiff gas-permeable lens may be more efficient. Stiff gas permeable lenses have a longer initial modification time, but once this has passed they are generally simply as comfortable as soft contact lenses and they are frequently easier to care for.

Toric lenses are readily available in every using schedule from daily non-reusable to long-term wear.
