Glasses and Contacts for Astigmatism from Yakima Vision Center

If you just seem to resolve the details of the world around you into sharp, clear visual focus not matter how much you squint or strain, you may be dealing with a common vision problem known as astigmatism. This issue can be somewhat trickier to correct that straightforward nearsightedness or farsightedness, especially if you seek contacts for astigmatism. Fortunately, your Optometrist at Yakima Vision Center can provide a variety of options, including special types of specialty contacts in Yakima.glasses for astigmatism from your optometrist in yakima

Understanding Astigmatism

Astigmatism is a kind of refractive error, a structural problem that causes the eye to refract incoming light incorrectly. In this case, the cornea of the eye does not follow a normal smooth contour and spherical shape. The pits and bulges of astigmatism are measured along lines called meridians that may extend from the center of the cornea along regular (perpendicular) or irregular patterns, just as the hands of a clock may be arranged in different relationships to each other. Typical astigmatism of the regular variety results in the cornea that is slightly oval instead of spherical. In some people, astigmatism also affects the lens behind the cornea, aggravating the refractive error.

Astigmatism can make parts of your vision either nearsighted (myopic astigmatism) or farsighted (hyperopic astigmatism). These abnormalities can produce blurred vision, not just at one distance but at multiple distances. People with astigmatism tend to struggle with eye strain and headaches in their efforts to maintain focus on text or other items for extended periods.

Corrective Options from Your Optometrist at Yakima Vision Center

Your  Optometrist at Yakima Vision Center uses sophisticated diagnostic methods for measuring the degree and patterns of your astigmatism in exacting detail. Retinoscopy can reveal the presence of astigmatism, at which point your eye doctor can use a device called a phoropter to mix and match lenses in front of the eye until you can read an eye chart clearly. This gives us an accurate prescription for eyeglasses that can correct for your astigmatism.

Contacts for astigmatism require additional evaluations. Since we must map the irregularities in the cornea with pinpoint precision, we use keratometry and corneal topography to measure each contour closely. Your eye doctor can then provide specialty contacts in Yakima such as:

  • Toric contacts - Toric contacts are shaped and weighted so that they remain in one fixed position on the cornea at all times.
  • Rigid gas permeable contacts - RGP contacts maintain perfect spherical contours as they sit on the cornea, unlike soft contacts which simply conform to the irregular meridians underneath them.
  • Hybrid contacts - Hybrids are rigid but rimmed by softer material, making them a good choice of you find RGP contacts uncomfortable.
  • Scleral contacts - Scleral contacts vault over the cornea completely (and comfortably) to provide superior correction for severe astigmatism.
