However, if you aren’t careful, they can harm your vision. You have to undergo a comprehensive trial to find whether you are suitable to wear a contact lens. Underlying eye conditions can make it illegible to wear lenses. So who cannot wear contact lenses? Let’s find out.

Who Cannot Wear Contacts Lenses?

Whether you are eligible to wear contacts depends on the decision of your optometrist. Your optometrist will make the final decision. Here are some underlying issues where you cannot use your contact lenses.

Dry Eye Syndrome:

Dry Eye Syndrome

Dry eye syndrome is one of the most common conditions which can get in the way of successful contact lens wear. To feel comfortable in contact lenses, you need to have enough lubrication in your eye.

Human tears contain oil, water, natural antibiotics, vitamins, and minerals. Every time you blink, you renew your tears. Tears can assist keep lenses moist and lubricated. If your eyes don’t have enough lubrication, the lenses can become dry. Your vision may fluctuate and will aggravate the condition of dryness in the eyes.

Steps to Address This Problem:

Severe dryness in the eyes can affect your ability to wear lenses. Usually, your optometrist will recommend you not wear contact lenses.

Furthermore, if you wear contacts with dry eyes can cause corneal scarring. To address this problem, your ophthalmologist will execute the following strategies.

  • Recommending the use of a special water gradient and daily disposable contacts
  • Fitting a specialized and customized scleral contact lens
  • Your optometrist may ask you to use lubricating eye drops
  • Insertion of plugs into the tear drainage canal

Severe Eye Allergies:

If you are suffering from eye allergies, wearing contacts lenses can be an issue. And if you wear contacts in the presence of allergies, there may be severe repercussions. Pollens, cigarette smoke, and mould can flare up allergies in your eyes.

When exposed to these allergens, the eye cells release histamines to protect the cornea. It is this chemical reaction that inflames the blood vessels.

Here are some of the common types of allergies you should know.

  • Seasonal or perennial conjunctivitis
  • Atopic keratoconjunctivitis
  • Vernal keratoconjunctivitis

Allergic conjunctivitis and perennial allergic conjunctivitis are pretty common. If you tend to suffer from these eye allergies often, you’re not ideal for wearing contact lenses.

How to Address This Issue?

Your suitability to wear lenses depends heavily on the severity of the allergy. In most cases, optometrists will administer antihistamines. Antihistamines can successfully cure allergies. But they can dry out the mucus membranes.

In other words, you will be suffering from dry eyes, which can make wearing contact lenses tough. So, that’s why most optometrists will suggest you use antihistamines and eye lubricant drops in tandem.

Special and Unique Cases:

Optometrists have many factors to select from to fit contacts for patients with varied types of eye conditions. People who are suffering from astigmatism can’t wear soft contact lenses because a soft contact lens can’t provide that level of clear vision. If you have high myopia or other lingering eye conditions, you may need customized lenses. Listen to the inputs given by your eye care specialist. Moreover, if you have astigmatism, the optometrist may recommend special lenses.
