Astigmatism is a refractive error usually caused by an irregular curvature on the surface of the eye. As light enters the eye it is focused on two points instead of a single point needed for clear vision. Normally the curve on the surface of the eye is equal from left to right and from top to bottom, giving the surface of the eye an equally round shape like a ball.

With astigmatism one of these curves is elongated making the surface of the eye oval shaped. This could, for instance, cause the light being refracted by the horizontal axis of the cornea to focus on a different point than the light being refracted by the vertical axis.

This causes two points of focus instead of one. If the points are focused before the retina the astigmatism is considered nearsighted or myoptic. If the points are focused past the retina it is considered farsighted or hyperoptic.

Symptoms of astigmatism include headaches, eye strain and fatigue. Severe astigmatism can cause a blurriness of images at all distances, while milder cases may cause blurriness only at certain distances. If you suspect you are suffering from astigmatism, ask your doctor for advice. Successful corrective measures include contact lens or refractive surgery.

So you’ve had your eyes examined and picked out your new frames, and now you have an array of lens options from which to choose. One important option to consider is investing in an Anti-reflective coating, also known as AR coating. This feature has multiple advantages that can benefit almost anyone who wears glasses.

Today’s modern lens materials have a higher refraction index than previous materials did, which means they can produce a stronger prescription with a thinner and lighter piece of lens. The trade-off is that they are more prone to reflection and glare. AR coating will cut the glare, and also some formulations will even strengthen and harden the newer plastic materials.

If you drive at night, you probably have noticed that the headlights of the other cars make it hard to see. An Anti-reflective coating reduces the amount of glare you encounter, enabling you to be a safer night-driver.

AR coatings also benefit computer users. Tests have shown that glare from computer monitors can cause extra vision stress, and add pressure on the eyes. But with Anti-reflective lenses, computer users can work at their monitors with less irritation to their eyes.

Another benefit of AR coatings is that they actually let in more light. You will have better overall vision, with higher contrast and clarity—especially in dim settings.

And let’s not forget to point out that with AR-coated lenses your glasses will look better on you and in photos. Without the glare on the front of your glasses, people will be able to see your eyes more clearly—which is always a good thing!

Talk with your eye care professional to determine which AR lens coatings are best for your lifestyle and your lenses.

Diabetic retinopathy, which is a complication of diabetes that affects the eyes, is detected during a comprehensive eye exam that includes: Visual acuity testing. Dilated exam in which drops are placed to widen the pupil to allow examination of the retina. Tonometry. Measurement of the eye pressure inside the eye. Supplemental testing may include:...
