Myths about contact lenses you still believe

For as long as contact lenses have been around, there have been rumors and myths circling about them. You don’t have to search too far to stumble upon terrifying stories with haunting photos of people whose eyes have been damaged by contact lenses. However, the reality is actually much less frightening. Contact lenses are, in fact, safe and comfortable for your eyes, and those horror-like scenarios are extremely rare. Such cases are almost always caused by inappropriate lens care or by wearing lenses for much longer than prescribed.

Here are the answers to some of the most frequently asked questions about contact lens nightmares.

1. Can contact lenses slip behind your eye?

Myth of the lost contact lens in the eye

Have you heard the story of “that guy who lost a lens in his eye and never found it again”? We have good news for you. It’s a myth! The lens might become displaced when your eyes are overly wet or if you rub them too hard, but it cannot get stuck behind your eye. Ever.

As Doctor Louis Cantor from the American Optometric Association explains: “The contact lens can only go as far as the crease in the conjunctiva under the upper eyelids, and it cannot go behind your eye”

Did you know?
The anatomy of the eye itself makes it impossible for a lens to get lost in your eye.
The membrane known as the conjunctiva folds at the back of the eyelids and creates an outer covering of the eyeball, making it impossible for any foreign particle to fall behind the eye.

2. Does wearing contact lenses worsen your vision?

No, wearing lenses does not worsen your vision. Prescription changes are perfectly normal throughout many people’s lives. As we age, our eyes go through physical changes that affect our vision and put us at a greater risk of developing conditions such as nearsightedness (myopia), cataracts or AMD. Wearing contact lenses does not make us more vulnerable to these conditions and doesn’t worsen eyesight.

According to Gary Heiting, OD, a senior editor for, “This is a common concern because many contact lens wearers are nearsighted children or teenagers whose eyes are still changing.”
So, you can be confident that wearing contact lenses will not negatively impact your vision.

3. Can contact lenses blind you?

No, contact lenses themselves cannot cause blindness. However, it is extremely important to clean them thoroughly every day and replace them at the end of the prescribed period. Not cleaning your lenses properly and not following hygienic procedures can lead to discomfort or even eye infections, but not blindness.

The truth, as described by Dr. Thomas L. Steinmann, a professor of ophthalmology at Case Western Reserve University, is that hygiene is the most important factor. “While contact lens use is safe, not caring for contact lenses properly or failing to follow contact lens safety rules can lead to serious problems," he says.

Did you know?
You need to clean your contact lenses on daily basis to remove deposits that can be left by your hands, eyelids, face or tears. The most effective method is by rubbing the lenses with solution in your palm every day before and after wearing.

4. Can contact lenses melt?

Maybe you have heard of the urban legend that says you should remove your contact lenses when attending BBQ parties or campfires to prevent them from melting on your eyes. Relax, this is just another rumour. Unless you set them on fire, contact lenses cannot melt. And, they definitely will not melt in your eyes as a result of exposure to normal heat or weather conditions. Contact lenses are made of hydrogel, and their melting point is nowhere close to your body temperature. Moreover, your contact lenses undergo sterilisation at approximately 120°C before they are packaged in order to kill all bacteria and germs. So, if you can stand the heat, your contacts can, too.
