Astigmatism is one of the most common causes of blurry vision. It can be present from birth, or it can develop after eye surgery. Astigmatism can become worse over time, and you may need updates of your prescriptions for astigmatism contact lenses or glasses to maintain good vision. Our optometrists at Highlands Optometry in Bristol and Wise can help correct your astigmatism.
Astigmatism causes blurry vision, but not just up close or far away. If you have astigmatism, you will see a blur no matter how near or how far the object you are looking at is from your eye. Astigmatism usually does not affect your entire field of vision. Because of this, you may develop headaches and eye strain from constantly trying to get a clearer image of the world around you, especially if you spend extended periods of time looking at a screen.
Our eye doctors will test your visual acuity. This is the test that results in the "20 over'' number and determines how well your vision compares to the ability to see a letter that should be seen clearly at 20 feet. The optometrist will also use an instrument called a keratometer to measure the curvature of your cornea, which covers your eye.
Using a keratometer is particularly important for prescribing contact lenses to correct astigmatism. Our optometrist also performs a refraction test. This is the "Which is better?" test, where you tell the optometrist which lens gives you a better image. With all of the advances in modern vision technology, your input about which lenses help you the most is still very important.
It is possible to refer our patients to a surgeon for laser eye treatment or we can prescribe a "retainer" that works on a principle sort of like braces for your teeth. However, most people choose to simply rely on eyeglasses or contact lenses to correct their astigmatism.
