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. 

When you blink, tears are produced to cleanse and lubricate your eyes. Excess tears are drained away through the tear ducts into the sinus cavity. That is why your nose runs when you cry.

The tears enter the nasal lactermal duct through the punctum. You can see in this diagram that there is a punctual port on both the upper and lower eye lid of each eye.

If your cornea isn't getting enough moisture, you could have dry eye complications. Often times, dry eye conditions can be treated with over-the-counter eye drops. If this type of therapy doesn't work effectively, other treatment options for dry eyes may include prescription eye drops or punctual plug inserts.

Punctual plugs can be used to partially or fully block the tear ducts to help retain tear film moisture. Your eye doctor might insert temporary plugs that may dissolve in a few weeks to test you for compatibility and effectively. If they work well, your doctor can easily insert permanent plugs that do not dissolve.

Talk to your eye care professional for more information about dry eye syndrome and treatments involving eye drop therapy and/or punctual plugs.
