Consequences of Incorrect Use of Contact Lenses

contact lenses incorrect use

Contact lenses are a great and convenient option for people who need to improve their vision. However, they shouldn’t be used without initially consulting with an eye doctor and proper prescription. A consultation will ensure that you are wearing the right prescription glasses to correct your vision problems. An eye care professional or optometrist can advise you on the proper way to care for your eyes.

A contact lens wearer needs to be aware of the symptoms of improper use of contact lenses to avoid further aggravating their eye condition.

When can you have the wrong contact lens prescription?

If you buy your contact lenses without a prescription, chances are you’re not going to have the right prescription. Even if an optometrist fits you for contacts, your vision can change over time and you may need a new prescription. If you switch eye care providers, the new provider may give you a different prescription.

Wear someone else’s prescription contact lenses

It is not advisable to share contact lenses with anyone else, as this can lead to serious eye infections. Also, each person’s eyes are unique, so their prescription contact lenses are also specific to them. Wearing someone else’s prescription contacts can cause headaches, blurred vision, and discomfort. It can also lead to more serious problems, such as corneal ulcers.

Wearing the wrong prescription long term

Just like with eyeglasses, it is important to make sure that you are wearing the right prescription contacts. Wearing the wrong prescription contacts can cause headaches, eye fatigue, and blurry vision. If you find yourself squinting or having to strain your eyes to see, then it is likely that you are wearing the wrong prescription contacts. In some cases, it can also lead to amblyopia or “lazy eye”.

Wearing expired contacts

You might not realize it, but contact lenses have a shelf life and expiration date. This is because they are made of materials that can degrade over time. Wearing expired contacts can cause irritation, redness, and discomfort. It can also lead to more serious problems, such as corneal ulcers.

Having an old prescription 

If you have an expired prescription for contact lenses, it is important to get a new one. This is because your vision can change over time and an old prescription may no longer be accurate. Wearing contacts with an outdated prescription can cause eye strain, headaches, and blurry vision.

How do you know if you’re wearing the wrong contact lens prescription?

What are the consequences of use of wrong prescription contact lens?

Although it will not ruin your eyes, it will give you headaches and will not be any help at all in improving your vision. Wearing the wrong prescription is just a waste of money. To avoid this, make sure that you get your eyes checked so the doctor can recommend the best contact lens prescription to improve your vision.

#2. Discomfort and Irritation


Contact lenses should fit into the cornea properly. An ill-fitting lens will move around the eye and even possibly scratch the eye surface, causing irritation. Some disposable lenses are meant to be worn daily, some weekly and others can be worn monthly. Not following the schedule of replacement indicated can cause irritated eyes and even infection.

#3. Headaches

Wearing the wrong prescription contact lenses can also cause pain. This is because the eye is trying to focus on an image that is not really there, causing strain and ultimately, pain in the head.

#4. Dry Eyes

If you already have dry eyes, wearing the wrong prescription lenses will only make it worse. The lenses will not only irritate your eyes but will also make them drier. This is because the lenses will not allow enough oxygen to reach the cornea, causing the eyes to become red and itchy. If you’re suffering from eye dryness, it’s best to consult with an eye doctor before buying any type of contact lens.

#5. Eye redness

Eye redness is another common symptom of wearing the wrong contact lenses. This is because the lenses are not letting enough oxygen reach the eye, causing the blood vessels in the eyes to dilate and become more visible. If you notice that your eyes are red more often than usual, it’s best to consult with an eye care professional.

#6. Sensitivity to light

If you find yourself squinting or having a hard time looking at bright lights, it could be a sign that you’re wearing the wrong contact lens prescription. This is because the lenses are not allowing enough light to enter the eye, causing discomfort. If you experience this symptom, it’s best to see an eye doctor so they can determine if you need a new prescription.

#7. Corneal Ulcers
