Unlock Precision Vision: Toric Lenses for Astigmatism
Astigmatism is a common eye condition that causes blurred vision. It is caused by an irregular shape of the cornea, the clear front part of the eye. The cornea is typically round, but in people with astigmatism, it is more oval or egg-shaped. This can cause light to focus at multiple points in the eye rather than at a single point on the retina.
There are two main types of astigmatism: corneal astigmatism and lenticular astigmatism. Corneal astigmatism is the most common type and is caused by an irregular shape of the cornea. Lenticular astigmatism is caused by an irregular shape of the lens inside the eye.
Astigmatism can be corrected with glasses, contact lenses, or surgery. Glasses are the most common way to correct astigmatism, but contact lenses can also be a good option.
What Are Toric Contact Lenses?
Toric contact lenses are designed to correct astigmatism.
Toric contact lenses have a different power in two different meridians (directions) to correct the irregular shape of the cornea. This allows light to focus at a single point on the retina, resulting in clear vision.
Toric contact lenses are available in both soft and rigid gas-permeable (RGP) materials. Soft toric contact lenses are more common, as they are more comfortable to wear. However, RGP toric contact lenses may be a better option for people with severe astigmatism or who have difficulty keeping soft toric lenses in place.
Benefits of toric contact lenses:
- Clear vision at all distances
- No need to wear glasses
- More natural field of vision than glasses
- Improved appearance
