The Do’s and Don’ts of Proper Lens Care

If you’ve ever slept in your contact lenses, worn disposable lenses past the prescribed replacement schedule, rinsed your contact lenses with tap water or gone for a dip in the community pool without removing contacts from your eyes first, it’s time to rethink your habits.

lensMost problems associated with contact lenses cause minor irritation, but serious eye infections from poor lens hygiene can be extremely painful and may lead to permanent vision loss. About 80 to 90 percent of contact lens-related eye infections are bacterial. A type of infection you can get is called pseudomonas aeruginosa, a fast-growing bacterial infection that can lead to a hole in your cornea. Unfortunately, patients who get this infection have a high chance of permanent scarring and vision loss. Beyond bacteria, fungal infections are also potential threats to your vision.

Do:

  • Always wash and thoroughly dry your hands before handling contact lenses.
  • Carefully and regularly clean contact lenses as directed by your eye care specialist. If recommended, rub the contact lenses with your fingers and rinse them thoroughly before soaking the lenses overnight in multipurpose solution that completely covers each lens.
  • Store lenses in the proper lens storage case, and replace the case at least every three months. Clean the case after each use, and keep it open and dry between cleanings.
  • Use only fresh solution to clean and store contact lenses. Never reuse old solution—it loses its effectiveness. Change your contact lens solution according to the manufacturer’s recommendations, even if you don’t use your lenses daily.
  • Always follow the recommended contact lens replacement schedule prescribed by your eye care specialist.
  • Remove contact lenses before swimming or entering a hot tub.Avoid tap water to wash or store contact lenses or lens cases.
  • See your eye care professional for your regularly scheduled contact lens and eye examination.

Don’t:

  • Use cream soaps. They can leave a film on your hands that can transfer to the lenses.
  • Use saliva to rinse or lubricate your contact lenses
  • Use homemade saline solutions. Improper use of homemade saline solutions has been linked with a potentially blinding condition among soft lens wearers.
  • Put contact lenses in your mouth or moisten them with saliva, which is full of bacteria and a potential source of infection.
  • Use tap water to wash or store contact lenses or lens cases.
  • Use products not recommended by your eye care specialist to clean and disinfect your lenses.
  • Use saline solution and rewetting drops not designed for contact lenses.
  • Sleep in contact lenses. The contact lens and your eyelid act as a double barrier, potentially trapping bacteria on the lens directly on your eyes.

Proper Contact Lens Care Provides Best Vision, Comfort and Ocular Health

Proper contact lens care is essential for the best contact lens wearing experience. Mr. Ward, Director of the Emory Contact Lens Service has shared some valuable information about taking care of your contact lens in the article below. On Tuesday join us for additional tips for people who wear contact lenses and wear cosmetics.contact lens case - proper contact lens care

Contact lenses provide alternatives to spectacles, and contact lens wearers report better peripheral vision, depth perception and overall vision quality. Contact lenses can correct near-sightedness, far-sightedness, astigmatism and even correct the need for reading glasses. They are also used to manage some ocular surface diseases.

Contact lenses fall into two basic material types: soft contact lenses (SCL) and rigid gas-permeable (GP) lenses. Soft lenses account for the great majority of the contact lens market. GP lenses require more precise fitting and are often used as specialty devices to correct high prescriptions and/or to manage various ocular disorders and may require longer lens-adaptation time. Regardless of lens type, careful attention to lens care instructions can provide good vision and life-long lens wearing comfort.
Proper lens care depends on the lens type, wearing schedule and other factors. Single-use or daily-disposable soft lenses are prescribed to be worn once and discarded. This is theoretically the safest lens wearing modality in that no lens cleaning, lens care or storage case is required for this modality. Other daily wear soft lenses may be replaced every 2 weeks, monthly or by other schedule. Any and all lenses that are removed each day must be cleaned and disinfected prior to their reuse. Your eye care practitioner should provide specific instructions relative to your lens wear and care needs. General lens care instructions and Dos and Don’ts are bullet-listed below.

A word of caution –
Contact lens wear is quite safe as long as proper lens and storage case care are followed. However, improper lens wear and care can put the lens wearer at risk for serious consequences. Sight-threatening microbial keratitis (corneal ulcer) is the most significant adverse event associated with contact lens wear and is largely preventable. The contact lens storage case is the most likely potential reservoir for contact lens related ocular infections. Therefore, lens storage case care should be high on the list of important lens wearing instructions. Contact lens cases are not meant to be family heirlooms; cases should be replaced regularly, at least every 1-3 months.

The Bullet List of Contact Lens Care Recommendations

  • Hand washing: Always wash your hands before handling contact lenses. Use mild, basic soap and avoid antibacterial, deodorant, fragranced or moisturizing liquid soaps (many liquid soaps have moisturizers that can contaminate your contacts from handling).
  • Cleaning, rinsing, and disinfecting: Digital cleaning (rubbing the lens with your finger in your palm) removes dirt and debris and prepares the lens surfaces for disinfection. Rub & rinse thoroughly, even if the product is labeled “No Rub”. Lens storage solutions contain chemicals that inhibit or kill potentially dangerous microorganisms while the lenses are soaked overnight.
    • Contact lenses should be cleaned when removed from the eye.
    • Do not re-use old solution or “top-off” the liquid in the lens storage case. Empty the storage case daily and always use fresh solution.
    • Do not use lens care products beyond their expiration dates. Discard opened bottles after 28 days.
    • Do not allow the tip of the solution bottle to come in contact with any surface, and keep the bottle tightly closed when not in use.
    • Do not transfer contact lens solution into smaller travel-size containers.
  • Keep your contact lens storage case clean (inside and out).
    • All lens storage cases should be emptied, rinsed, wiped, and air-dried between uses.
    • Keep the contact lens case clean and replace it regularly, every one to three months.
    • Do not use cracked or damaged lens storage cases.
    • Take care to remove residual solution from surfaces of lens case and solution bottles.

Other Dos and Don’ts

  • Do not wear your lenses during water activities (swimming, hot tubs, showering, etc).
  • Soft contact lenses should not be rinsed with or stored in water. Soft lenses will change size and shape if exposed to water.
  • Do not put your lenses in your mouth.
  • Do not use saline solution or re-wetting drops in an attempt to disinfect lenses. Neither is capable of disinfecting contact lenses.
  • Wear and replace contact lenses according to the prescribed schedule.
  • Follow the specific contact lens cleaning and storage guidelines from your eye care professional.
  • Do not change lens care products without first checking with your eye care practitioner.
  • Spare rigid (GP) lenses should be stored dry for long term storage { clean, rinse, dry}. New or dry-stored GP lenses should be re-cleaned and disinfected prior to lens wear.
  • Do not store soft lenses in the storage case for an extended period of time. “Spare” soft contact lenses should be new and stored in their original and unopened packaging.
  • Do not sleep in your contact lenses unless specifically approved to do so by your eye care practitioner.
