Defining Astigmatism: Acuvue Contact Lenses For Astigmatism

An astigmatism is a common vision problem that can occur in children and adults. It does not matter whether the patient is nearsighted or farsighted, or wears glasses or contact lenses, because astigmatism can affect anyone. Fortunately, astigmatism is easily corrected. A simple prescription for glasses or contact lenses for astigmatism will solve the problem.

An astigmatism is caused due to an uneven or oddly shaped cornea. The cornea is supposed to be spherical, however it appears more oblong or oval when an astigmatism is present. The most traditional cause of astigmatism is due to DNA – in other words, it is hereditary. Other causes include an eye injury that results in scarring on the cornea, certain eye surgeries, and thinning of the cornea. An astigmatism produces slightly blurred vision, and when left uncorrected, can cause headaches and eye strain.

It is important to schedule regular annual eye exams because it can worsen over time, so it is necessary to keep a close watch and adjust prescriptions for glasses or contact lenses as needed. Both glasses and contact lenses are usually suitable corrections for an astigmatism. Sometimes, it is so severe that contact lenses cannot be used, however, that is not normally the case.

In the past, contact lens wearers with an astigmatism had few options. One option was to go back to wearing glasses. Another option was to wear less comfortable hard or rigid gas permeable lenses. The other choice was to simply live with it, risking the adverse effects of headaches and strain on the eye.

Today, the Acuvue brand offers two great options for contact lens wearers suffering from astigmatism. The contact lenses for astigmatism that are available today are called toric lenses. While toric lenses are formed out of the same materials as regular lenses, the design of the lens is different. They do not move around or rotate on the eye. They are specially designed to stay in place when you move your eyes to look around.

Acuvue Advance for Astigmatism is one option released by Acuvue in 2004. Specific features of these lenses include Hydraclear Technology and Accelerated Stabilization Design. Hydraclear Technology allows lenses to remain more moist, which keeps them more comfortable. Accelerated Stabilization Design is a characteristic that keeps the lens properly positioned on the eye. When the wearer moves the eye to look around, or blinks, the lens is designed to automatically realign itself into the correct place.

Acuvue Oasys for Astigmatism is a lens developed and marketed by Acuvue in 2008. It is similar to the Advance lenses, as both feature Hydraclear Technology and Accelerated Stabilization Design. The Oasys lenses can be worn overnight for 6 nights in a row. This is possible because more oxygen is able to permeate the lens and reach the eye. It is recommended that these lenses be changed every two weeks.

Eye exams and lenses for astigmatism are usually significantly more expensive than regular lenses and exams. Additional measurements are needed, and they are very precise, which takes the doctor longer. The lenses are more costly as well due to the way they are manufactured, but for most people, it is worth the extra money to have contact lenses for astigmatism that really work.
