Toric Contact Lenses for Astigmatism

Toric Contact Lenses for Astigmatism

The normal cornea is a spherical and symmetrical shape, with only one curve. Light passes through one focal point, reflecting onto your retina. In a nutshell, that is how you see. When you have astigmatism, your cornea has an elongated shape that creates a second curve. As a result, this second curve interferes with how light is focused on your retina. Astigmatism causes distorted and blurred vision for both near and far. Prescription eyewear can correct this condition and give you crisp vision. Our eye doctors and Louisville contact lenses specialists will give you a precise vision prescription and help you choose the best eyewear for your needs.

How can contact lenses correct astigmatism?

When you envision contact lenses, you probably think of a neat circular disc, and you may wonder how this symmetrical shape can fit eyes with astigmatism. In general, you are correct! Standard contact lenses cannot correct astigmatism. However, a specialized type of contacts – called toric contact lenses – is available.

What are toric lenses?

Toric contacts have an oblong shape and come in hard gas permeable (GP) and soft versions. The soft types of toric lenses, made from hydrogel or silicone hydrogel, are the most popular. They are available in various wearing schedules, including daily disposable, daily wear, and extended wear.

Specialty toric lenses have two prescriptions – one to resolve your nearsightedness or farsightedness, and one with a cylinder to correct your astigmatism. When toric contact lenses are in your eye, they must remain vertically aligned to provide clear vision – moving only up and down when you blink. The lenses are specially weighted with different thick and thin zones in order to accomplish this.

Is it hard to fit toric contact lenses?

Fitting toric lenses is more complicated than fitting conventional contacts. Our eye doctors are highly experienced and qualified in fitting both hard and soft toric lenses precisely, and we stock a wide range of torics in our Louisville contact lenses collection.

Sometimes, it takes a bit of trial and error until we identify the ideal toric contact lenses for your eyes. Our optometrists will work with you patiently until we find the perfect fit to give you smooth comfort and sharp vision.
