What is Astigmatism?
Astigmatism is an imperfection in the curvature of the eye's surface which causes blurry vision. Simply put, your eye's surface is supposed to be round like a baseball, but with astigmatism it is shaped more like a football. Astigmatism is completely normal and more common than you might think. You can be born with astigmatism, or you may develop it over time. It may also develop after an eye injury or eye surgery.
Astigmatism can typically be corrected with glasses or contact lenses. It all comes down to getting the best contact lenses to meet your needs.
Types of Astigmatism
Having astigmatism means that your eye surface has an irregular curve, and your eye has problems focusing light, which means blurry vision at near and far distances.
There are two types of astigmatism:
Regular - the cornea is curved more in one direction than another, which distorts vision and makes objects from near to far appear blurry or stretched.
Irregular – the curvature of the eye’s surface is uneven, or curved in multiple directions. Irregular astigmatism is less common than regular astigmatism.
Symptoms and Diagnosis of Astigmatism
- Blurry or distorted vision at all distances
- Eye fatigue
- Difficulty seeing at night
Astigmatism is diagnosed by your eye doctor during your annual eye exam by using various instruments and lenses to measure how your eyes focus. Be sure to communicate your concerns or blurry vision to your doctor during this time. If you do need vision correction for astigmatism, nearsightedness or farsightedness, your doctor will provide you with that prescription following a thorough exam.
How to Correct Astigmatism
Astigmatism can typically be corrected with eyeglasses, contact lenses, or refractive surgery. To accurately correct for astigmatism with contact lenses, a “toric” contact lens is required. This contact lens is made specifically for astigmatism and will correct astigmatism as well as nearsighted or farsighted needs.
What makes ACUVUE® contact lenses great for astigmatism?
- Contacts can offer freedom and flexibility from glasses, and ACUVUE® Contact Lenses for ASTIGMATISM can also solve nearsightedness and farsightedness.
- Typically, contact lenses can rotate on your eye as you blink or move your head throughout the day. For astigmatism, however, it’s especially important that your lenses stay in place for clear vision. The design of ACUVUE® contact lenses work with your eyelids’ natural movements, helping to realign your contacts with every blink.
- Your vision stays crisp, clear and stable – even if you have an active lifestyle!
- Easy to handle, insert and remove, and because of the contact lens’ design, it can’t be inserted upside down like most other lenses for astigmatism.
- ACUVUE® offers UV blocking across its entire line of astigmatism contact lenses†.

†Helps protect against transmission of harmful UV radiation to the cornea & into the eye. WARNING: UV-absorbing contact lenses are NOT substitutes for protective UV-absorbing eyewear such as UV-absorbing goggles or sunglasses because they do not completely cover the eye and surrounding area. You should continue to use UV-absorbing eyewear as directed. NOTE: Long-term exposure to UV radiation is one of the risk factors associated with cataracts. Exposure is based on a number of factors such as environmental conditions (altitude, geography, cloud cover) and personal factors (extent and nature of outdoor activities). UV-blocking contact lenses help provide protection against harmful UV radiation. However, clinical studies have not been done to demonstrate that wearing UV-blocking contact lenses reduces the risk of developing cataracts or other eye disorders. Consult your eye care practitioner for more information.
