Astigmatism is , similar to nearsightedness or farsightedness, a refractive error.  A refraction or refractive error is when there is an error in focusing of light by the eye. Usually light focuses on a single point on the retina to produce clear pictures but in an eye affected by astigmatism light does not focus on a single focusing point on the retina.  In eyes affected by astigmatism, light may get focused on multiple points , creating blurry vision.

Astigmatism and Toric Lenses

Let’s see what Astigmatism is how you can see betetr if you have Astigmatism with Toric Lenses .

The Symptoms of Astigmatism:

Instead of having difficulty or blurriness in near or distance vision, the symptoms of Astigmatism include a certain amount of blurred or distorted vision at all distances.  People affected with astigmatism might have to squint to see better or eye strain after prolonged visual tasks. Also headaches and eye straining are common problems due to astigmatism.

Astigmatism Cause :

Human cornea should be symmetrical but when one of it’s meridian is more curved than the other, astigmatism can occur. Also the lens inside the cornea can cause astigmatism.  Here are the different types of astigmatism and the causes.

Myopic Astigmatism :

When one or both the principal meridians of the eye are nearsighted and the two meridians have different degrees of myopia .

Hyperopic Astigmatism:

One or both the principal meridians of the eye are farsighted and the two meridians have different degrees of hyperopia.

Mixed Astigmatism :

One of the principal meridians is farsighted and the other is nearsighted .

 

How Can one Use Toric Lenses To Treat  Astigmatism:

Astigmatism is not a disease, and it can be treated with Visual correctors like Glasses and Contact lenses. For permanent visual corrections LASIK can also be used as well as surgery .  Contact lenses are a good choice for vision care for Astigmatism as it’s easy to use, and gives natural vision without altering your looks. Here’s how Toric lenses from Astigmatism work.
The shape of a Toric contact lens creates different refractive, or focusing, powers on the vertical and horizontal orientations on it’s surface. The refractive power is increased or decreased as the lens moves.

Through the different refractive powers along the horizontal and vertical orientations, Toric lenses can help with astigmatism as it offers different amounts of refractive correction at different orientations.

There are many Toric Lenses available from various brands. You can buy Toric Contact lenses for Astigmatism from GKB Opticals and experience the comfort and easy vision correction.
