Do’s and Don’ts of Contact Lenses

Specialists have noticed a rise in eye infections among contact-lens wearers and are warning users to take extra care. Bacteria, fungi and micro-organisms can stick to contact lenses and cause pain, irritation and serious harm. So here are some of the risks, and the do’s and don’ts:

Don’t sleep with your lenses in

Unless your optician has said you can, it is a bad idea to leave your contacts in when you go to bed. Most contact lenses are not designed for this and extended wear can aggravate the cornea – the transparent outer covering of the eye, leaving it more vulnerable to infection.

Don’t shower or swim with your lenses in

Water-borne bacteria and other bugs, can attach to contact lenses during swimming and cause infection. If you want to swim with your contacts in, use a pair of tight-fitting swimming goggles to help protect your eyes.

Do clean your lenses properly

To disinfect your lenses, soak them in solution in a storage case for the recommended amount of time.
Never re-use disinfecting solution or top it up. It must be discarded and replaced with fresh solution each time the lenses are stored.
Only use the care products recommended by your practitioner.
Rinse your storage case, leave it open to dry after use each day, and replace it monthly.
Clean the storage case each week, using a clean toothbrush and contact lens solution.
Make sure your hands are clean. Wash, rinse and dry your hands thoroughly before handling your lenses to prevent spreading nasty germs.

Don’t leave them to soak in a glass of water

It may be tempting to cut corners, especially if you are away from home and have forgotten to bring your lens-cleaning kit. But don’t. Tap water can still carry bacteria that are harmful to the eyes.
Saliva is not a hygienic way to clean or wet your lenses.

Do be extra careful when putting them in and taking them out

Take care not to catch the lens or the eye with your fingernails.
Don’t mix your right and left lenses up; get into the habit of inserting and removing the same lens first.
Before you put lenses in, check they are not damaged or inside-out. The lens should be shaped like a cup. If it is inside-out it will be shaped like a saucer, with the edges facing out.
Give the lens a rinse with saline or conditioning solution and place it on to the tip of the index finger of your dominant hand.
Pull the lower eyelid down with the middle finger of the dominant hand and lift the upper eyelid with your other hand and gently place the lens on the eye without blinking.
When the lens is on the eye, close the eye slowly and blink gently a few times until the lens begins to feel comfortable.
To remove soft lenses, keep your chin down and look upwards.
Separate you eyelids in the same way as before and slide your contact lens down on to the white of your eye. Then gently pinch the lens with your thumb and index finger. Never use your nails.
To remove hard lenses, place your middle and ring finger at the outer corner of your eye and pull your eyelids tight over towards your ear. Blink – the lens should come out.
Dispose of or store the lenses appropriately.

What if my eye is red or feels odd?

Never ignore problems or discomfort. Remove the contact lens and seek medical advice.
