Many folks think if they have astigmatism, they can’t wear contact lenses. It’s really a myth. Today, there are many options for correcting astigmatism with contact lenses. The choices for astigmatism contacts include Toric, gas permeable (GP) and hybrid lenses.
Toric contact lenses are soft contact lenses made of hydrogel material, silicone hydrogel or rigid GP lens material. These contact lenses feature different powers in different meridians to correct nearsightedness or farsightedness that specifically arises in astigmatism. Toric contact lenses are designed with features that allow the lens to deliver clear vision. Many are weighted at the bottom to prevent rotation. They have a more complex design, which requires an expert fitting.
GP contact lenses are a popular choice for astigmatism contacts. GP contact lenses are rigid and do not conform the irregular shape of the cornea. The lens replaces the irregular shape of the cornea using its refracting surface to correct astigmatism. Some people with astigmatism experience sharper vision with GP contact lenses when compared to Toric contact lenses. It’s important to note that there are Toric GP lenses, but generally these are used for those who have unusual types of astigmatism or high levels of astigmatism. Each GP contact lens is custom-made to specific parameters.
Hybrid contacts are another choice for astigmatism contacts. These contact lenses are made of a GP lens material surrounded by a zone made of silicone hydrogel or hydrogel material. Hybrid contacts provide both sharp vision and comfort. They have thinner edges than GP contact lenses, and there is less risk of the lenses coming off during physical activity. Like GP contact lenses, hybrid contact lenses are custom-made.
