Contact Lenses and UV Light

As we continue in this series on ContactLenses from Liz Segre article on AllAboutVision.com, lets look at why some contact lenses now have UV-blocking.

Researchers have linked ultraviolet (UV) light to the formation of cataracts. Exposure to excessive UV light also may result in a condition called photokeratitis.

That's why some contact lenses now contain a UV-blocking agent. You can't tell if a contact lens has a UV blocker just by looking at it — the blocking agent is clear, so as not to disturb vision. The contact lens packaging will specify if the product has a UV blocker.

·         UV-blocking contacts are not meant to replace sunglasses. A contact lens covers only your cornea, not your entire eye.

·         UV-blocking contact lenses do help protect the portion of the white of your eye that is covered from formation of growths such as pingueculae and pterygia.

·         Sunglasses with UV protection can cover more of your eye and the parts of your face that surround the eye, depending on the size of the sunglass lens.

Applying and Removing Contact Lenses

Before Applying Your Contact Lenses

Make sure you wash your hands thoroughly before applying your contact lenses, but avoid scented or oily soaps that might adhere to the lens surface. Especially avoid using products containing lanolin and moisturizing lotions.

Some eye doctors say to always apply the first contact lens in the same eye, so you'll avoid the possibility of mixing up lenses for the right eye and left eye.

•         DO make sure contact lenses and lens storage cases are cleaned and disinfected regularly.

•          DON'T place contact lenses in your mouth or use your saliva to wet them.

•         DO always rub contact lenses when you clean them, even if using a "no-rub" solution.

Removing Your Contact Lenses

If you are standing in front of a sink, use a clean paper towel to cover the drain where the contact lens might accidentally fall. Always wash your hands before removing contact lenses.

To remove soft contact lenses, look upward or sideways while you pull down on your lower eyelid. With a finger, gently maneuver the lens onto the white of your eye. Keep your fingernails short to avoid accidentally scratching and damaging your eye.

Are my contact lenses inside-out?

Many people new to contact lenses, and even some experienced wearers, have practical questions about contacts.

A question many newbie wearers have is: "How can I tell if my contact lens is inside-out?"

The trick is to place the lens on your finger so that a cup is formed. Then hold the lens up directly in front of your eyes so you're looking at the side of the cup.

If the lens forms a "U" with the top edges flared out, it's inside out. If it forms just a "U," it's in the correct position.

If you're wearing lenses with a handling tint, another way is to place the lens on your fingertip and then look down at it. The edge of a tinted lens should look very blue (or green, depending on the tint); that won't be the case if the lens is inverted.

Don't worry if you place a contact lens in your eye inside out. The lens will feel uncomfortable, but it can't do any damage.

Your eyes are the windows to the world but negligence and improper care can take a toll on your eyesight.

Healthy food: Food play important role in the vision of eyes. For keeping your eyes healthy you should eat healthy food. Foods with nutrients and the best sources of these nutrients are green, leafy vegetables such as spinach, kale, and collards, oily fishes.

Take care while using computers: Many people suffer from Computer Vision Syndrome, which is a temporary condition caused by frequent and prolong use of computer. Some of the symptoms are eyestrain, headaches, blurred vision, fatigue, dry eyes, difficulty focusing at a distance, neck, back, and shoulder pain, etc. So while using your computer, ensure proper lighting conditions to avoid glare on your computer or use an anti-glare screen if needed.

Quit smoking: Studies have shown that smoking can increasethe risk for macular degeneration, cataracts and optic nerve damage.

20-20-20 rule:  Use 20-20-20 rule. Every 20 minutes, take a 20-second break and look at something 20 feet away. Maintain an appropriate distance from your desktop.

                                            

Exercise: You can do the exercise for eyes by sitting in your room, on your favorite chair or at any time of the day. Close your eyes, gently massage you eyes in circular direction, and then wash your hands. You not need to go any gym or somewhere.
