Six Bad Things That Can Happen If You Don’t Wear (And Care For) Your Contact Lenses Appropriately

Photograph: Richard Austin/Rex Features

I have been wearing contact lenses for about twenty five years. Overall, I’ve been very happy with them, and have found that they have improved my vision as well as my self-esteem. As a very nearsighted person, my glasses have the proverbial “Coke bottle” lenses. Even though I’ve chosen “ultra-thin” lenses, the refractory nature of the plastic causes my eyes to appear unusually small, giving me the appearance of a juvenile badger (they have pretty small eyes for the size of their heads – check out the photo).

Needless to say, I prefer wearing contact lenses – but I must confess that I’ve been somewhat non-compliant in wearing them according to my eye doctor’s instructions. I’ve learned a few things from my mistakes, and from interviewing optometrists Jason Pingel and Christi Clausson about other patients who have been naughty. I will summarize six of the most common mistakes that contact lens wearers make, and explain what the potential harms can be. You can listen to the full podcast of this interesting interview, here:

  1. Wearing Your Contact Lenses For Too Long – this was my biggest personal mistake. It’s tempting to wear your contact lenses beyond the recommended replacement schedule in order to save money, or for simple convenience. My contacts felt so comfortable that I’d wear them (don’t gasp in horror) for months at a time, even sleeping in them at night. But after a while my eyes started hurting when I took my contacts out, which just perpetuated the cycle of over-wear. In effect, I was depriving my corneas of oxygen for long enough to kill some of the superficial cells, so when I took my lenses out it was like removing a bandage from a wound. My corneas were sensitive to light, touch, and even the wind. This medical condition is called “superficial punctate keratitis” and although it’s reversible with eye rest, it is quite uncomfortable. If you wear your contacts for too long, this could happen to you.
  2. Using Tap Water To Re-Wet Your Lenses – Sometimes when a piece of lint gets in your eye or your eyes are feeling dry you may be tempted to rinse your lenses with some tap water. Although that seems harmless enough, tap water is not safe for use with contact lenses. Tap water is not sterile, and it can contain bacteria or even protozoa that can cause serious damage to your eye. Just as you would never drink salt water, you should never expose your contacts to tap water. The risk of eye discomfort, alteration of the lens, pH imbalances, or even infection is not worth the risk.
  3. Not Washing Your Contact Lens Case Regularly – At least a third of contact lens wearers report cleaning their cases monthly or less often. Obviously, mold spores and bacteria are not good for the eyes, so if you aren’t cleaning your lens case frequently you are putting yourself at risk for eye infection and allergies. Lens cases should be rubbed and rinsed with sterile solution recommended by your eye care provider, dried with a lint free towel or and allowed to air dry with both the case and cap(s) down before re-use.
  4. Not Changing your Contact Lens Solution – Dr. Pingel told me that many of his patients admit to “topping off” their contact lens solution or storing them in the same solution from the day prior. This increases the risk of bacterial growth in the solution and lens case. The way I think of it – it’s like having a surgeon simply wipe off her instruments on her gown between patients. It’s much safer for her to dispose of the instruments or have them sterilized before the next use, right? The same goes for contact lenses and their solution.
  5. Not Washing Your Hands Before Touching Your Eyes Or Lenses – Our hands are exposed to hundreds of different bacterial strains, molds, dirt, and chemicals every day. Not washing your hands with mild soap and water prior to touching your contacts is like touching your eyeball to a door knob. Why take the risk of introducing chemicals or bacteria into your delicate eye area? It’s very important to wash your hands carefully before insertion and removal of contact lenses so as not to increase your risk of infection, allergy, or chemical burns of the eye.
  6. Not Sharing Your Contact Lenses With Others (Or Buying Them Without A Prescription) – While that might sound like an uncommon practice, it actually becomes an issue around Halloween time. With cosmetic lenses that can make your eyes look like anything from a cat to a zombie, it is tempting to share lenses with friends. However, you should not purchase or wear cosmetic lenses without an examination by an eye doctor and a prescription to ensure they fit safely and comfortably. Delicate corneal skin can be scratched, irritated, or even infected by unclean or ill-fitting lenses. No one wants their real eyes to look scary, right? So please don’t buy lenses without a prescription or share your lenses with others.

For more information about safe wear and care of contact lenses, I highly recommend that you check out the Healthy Vision & Contact Lenses e-brochure. It is a terrific summary of all the most important do’s and don’ts of contact lens wear and care – perfect for double-checking on your safe use behaviors, or teaching your kids/teens about how to care for their lenses. Or you can use my blog post and podcast to badger them (pun intended), if that’s more convenient.

Ultraviolet Radiation Damage Can Have Long Term Consequences For Your Eyes

If you were invited to be part of a nuclear radiation clean up crew, I bet you’d want to wear protective gear. Not just the white hazmat bunny suit, but the gloves, goggles, mask and booties as well, right?  But when it comes to ultraviolet radiation exposure, we often put on “half a suit” as it were. We cover our skin with sunscreen (maybe) but we don’t regularly protect our eyes. I’m not sure why we forget this step, but it’s time to get serious about eye protection.

In a recent interview with dermatologist, Dr. Jeanine Downey, and optometrist, Dr. Stephen Cohen, we discussed the long term damage that UV radiation can cause to the skin and eyes. I hope you’ll listen to our entire conversation here:

Sun damage of the skin has a familiar appearance – dark spots, wrinkles, thinning, and enlarged pores.  UV radiation causes visible damage to the eyes as well – yellowish corneas (the “whites” of the eyes), scars (called pterygia), and crow’s feet. Over time, eyelid skin can become cancerous from sun exposure, while eyeballs develop cataracts and macular degeneration (which can lead to blindness). The risk of these diseases and conditions can be greatly reduced with sun protection measures. And it’s not that hard to do…

Some quick tips to protect your eyes:

1. Wear a wide-brimmed hat to protect your face and eyes from the sun.

2. Wear wrap-around sunglasses that absorb at least 99 to100 percent of both UVA and UVB rays for maximum eye protection.

3. If you wear contact lenses, ask your eye doctor about whether or not your lenses have UV protection. ACUVUE® OASYS® Brand Contact Lenses offers the highest level of UV blocking available, blocking at least 90 percent of UV-A rays and 99 percent of UV-B rays. Although UV-blocking contact lenses provide important additional protection for wearers, they do not completely cover the eye and surrounding area, and should not be considered as a substitute for UV-blocking sunglasses. For maximum protection, UV-blocking contact lenses should be worn in conjunction with high-quality, wrap-around, UV-blocking sunglasses and a wide-brimmed hat.

4. Remember that UV rays are more intense when reflected from water and snowy surfaces. Just because it’s the winter time doesn’t mean you don’t need to wear your sunglasses.

So next time you reach for your sunscreen, please remember to take your hat and sunglasses with you too! Fortunately, bunny suits and booties are still optional for UV radiation protection. ;-)

Actress Meaghan Martin: Teenagers, Self-Esteem, And Contact Lenses

When I asked Meaghan Martin (star of Mean Girls 2, 10 Things I Hate About You and Camp Rock among others) what was the most difficult thing about being a teen these days, she didn’t hesitate: “Being a teen has always been difficult, but today there are so many ways to be rejected. Between Facebook, Twitter, and other online sites, it seems as if every day there’s a new way to be un-friended, excluded, or picked on.”

I interviewed Meaghan about her perspectives on teen self-esteem issues and the impact that physical appearance can have on young men and women. You can listen to the edited interview here (starts at minute 12:02):

The most striking thing about Meaghan is that she is a genuinely nice person. Down-to-earth, confident, empathic – she exudes an inner peace that is downright wholesome. How did she escape her teen years relatively unscathed by hormonal angst, I wondered? The secret, she said, was loving parents.

“I was a typical nerd as a kid. I had glasses, braces, and an asthma inhaler. But I didn’t care what others thought of me, because my parents told me that I was a good person who could do anything I wanted in life. They taught me self-confidence, and supported me 100% in anything I wanted to do. I was so blessed to have parents like that.”

I chuckled as I remembered my pre-teen and teen years, sharing with Meaghan that I was a lot like her – except that I had traded the asthma inhaler for acne. For me, Read more »

Medical Devices Injure 70,000 Kids Each Year

FDA researchers have published a study in Pediatrics that analyzed patient records from child and teen ER visits in 2004 and 2005. The investigators are reporting that 70,000 kids each year go to the ER because of issues caused by medical devices.

About a quarter of the injuries were from contact lenses, while the other major contributors were needles, wheelchairs, braces, and obstetric exam tools. The study also looked at the devices most likely to cause hospitalization, and they were found to be mostly invasive devices like ostomy appliances and implanted defibrillators. Read more »

Vitamin E-Infused Contact Lenses May Treat Glaucoma

44543444.jpgResearchers at the University of Florida in Gainesville have developed a vitamin E-secreting contact lens that can bring the valuable antioxidant directly to eyes.

Vitamin E is packaged into clusters within the lens and the aggregate works to slowly release the chemical while remaining invisible to the eye.

“These vitamin structures are like ‘nanobricks’,” said Anuj Chauhan, Ph.D., lead researcher of the study. “The drug molecules can’t go through the vitamin E. They must go around it. Because the nanobricks are so much bigger than the drug molecules -– we believe about a few hundred times bigger –- the molecules get diverted and must travel a longer path. This increases the duration of the drug release from the lenses.” Read more »
