Contact lens intolerance can be relatively common, especially if the lenses are not properly fitted or if the individual has underlying eye conditions. It can also be influenced by personal factors such as eye dryness or sensitivity. However, with proper care and attention to individual needs, many people are able to successfully wear and enjoy contact lenses. Let’s take a deeper look!

Common Causes:

  1. Incorrect fit: If the lenses are not properly fitted, they can cause discomfort and irritation.
  2. Eye dryness: If the eyes are not producing enough tear fluid, this can cause discomfort and make it difficult to wear contact lenses.
  3. Eye infections: Infections such as conjunctivitis or blepharitis can cause inflammation and make the eyes more sensitive to contact lenses.
  4. Allergies: Allergies to the materials used in contact lenses, or to the cleaning solutions used to maintain them, can cause irritation and discomfort.
  5. Environmental factors: Exposure to dust, smoke, or air pollution can cause irritation and make it more difficult to wear contact lenses comfortably.
  6. Eyelid problems: Conditions such as meibomian gland dysfunction or eyelid inflammation can interfere with the normal lubrication of the eyes and cause discomfort when wearing contact lenses.

If you are experiencing discomfort or intolerance with your contact lenses, Acuicyn Antimicrobial Eyelid & Eyelash Hygiene with Performance Stabilized HOCl may be the solution.

Incorrect Fit:

  1. Poorly fitting base curve: The base curve of the contact lens should match the curvature of your cornea for optimal comfort and vision. If the base curve is too steep or too flat, it can cause discomfort and irritation.
  2. Incorrect diameter: The diameter of the contact lens should be appropriate for your eye size. If the lens is too small or too large, it can cause discomfort and may not stay in place properly.
  3. Incorrect power or prescription: Contact lenses come in different powers or prescriptions to correct various vision problems. If the power or prescription is incorrect, it can lead to blurry vision and eye strain.
  4. Improper centering: The contact lens should be properly centered on your eye to ensure clear vision and comfort. If it is not centered properly, it can cause discomfort and vision problems.
  5. Incorrect material: Some individuals may be sensitive or allergic to certain materials used in contact lenses. If the wrong material is used, it can cause discomfort and may lead to eye infections.

It is important to have your contact lenses properly fitted by an eye care professional in order to ensure optimal comfort, vision and eye health.

Eye Dryness:

  1. Aging: As we age, the glands that produce tears may not function as well, leading to decreased tear production and dryness.
  2. Environmental factors: Air conditioning, heating, wind, smoke, dust, and dry air can all contribute to eye dryness.
  3. Medications: Certain medications can cause dry eyes as a side effect.
  4. Medical conditions: Autoimmune diseases such as Sjogren’s syndrome, rheumatoid arthritis, and lupus can cause dry eyes. Other conditions such as diabetes, thyroid disorders, and vitamin A deficiency can also contribute to dry eyes.
  5. Eye surgery: LASIK and other types of eye surgery can lead to temporary dryness due to nerve damage during the surgery.

If you experience persistent eye dryness, it is important to consult an eye doctor to diagnose and treat the underlying cause.

Eye Infections:

Conjunctivitis, also known as pink eye, is an inflammation or infection of the conjunctiva, which is the thin, transparent layer of tissue that lines the inside of the eyelid and covers the white part of the eye.

There are several different types of conjunctivitis, including:

  1. Viral conjunctivitis: This is caused by a viral infection and is highly contagious. It often starts in one eye and then spreads to the other.
  2. Bacterial conjunctivitis: This is caused by a bacterial infection and can be treated with antibiotics.
  3. Allergic conjunctivitis: This is caused by an allergic reaction, usually to pollen or other environmental allergens. It can occur seasonally or year-round.
  4. Chemical conjunctivitis: This is caused by exposure to irritants such as smoke or chemicals.

Symptoms of conjunctivitis include redness in one or both eyes, itchiness, a burning sensation, discharge or crustiness around the eyelid, and blurred or hazy vision. Treatment depends on the cause and may include antibiotic eye drops, antihistamines, or other medications to reduce inflammation. In some cases, home remedies such as warm compresses or artificial tears may be recommended.

Blepharitis is a common eye condition characterized by inflammation of the eyelids. It is a chronic condition that typically affects both eyes and is caused by bacteria or abnormalities in the oil glands at the base of the eyelashes.

There are two main types of blepharitis:

  1. Anterior blepharitis: This affects the outside front of the eyelid and is often caused by bacteria or dandruff from the scalp or eyebrows.
  2. Posterior blepharitis: This affects the inner eyelid and is typically caused by abnormalities in the oil glands, which can lead to the production of excess oil and the growth of bacteria.

Symptoms of blepharitis include redness, swelling, and itching of the eyelids, crusting or flaking of the skin around the eyelids, and a burning or gritty sensation in the eyes. In some cases, blepharitis may also lead to styes, chalazion, or problems with tear production.

Treatment for mild blepharitis typically involves a combination of self-care measures, such as warm compresses and cleaning of the eyelids to manage inflammation and control bacterial growth. In more severe cases, a doctor may also prescribe or dispense medications to treat underlying conditions that may be contributing to the development of blepharitis.


Reactions related to contact lens use can be due to allergies to the materials used in the contacts or the cleaning solutions used to maintain them.

Symptoms of contact lens allergies can include:

  1. Red, itchy, or watery eyes
  2. Sensitivity to light
  3. Swelling of the eyes or eyelids
  4. Discharge from the eyes
  5. Blurred vision

Some people may also experience an allergic reaction to the preservatives in certain contact lens solutions.

If you develop symptoms of an allergic reaction when using contact lenses, it is important to stop using the contacts and consult your eye doctor. They can help determine the cause of the allergic reaction and recommend alternatives, such as switching to a different type of contact lens material or cleaning solution.

Environmental Factors:

  1. Dust, smoke, and air pollution: Exposure to these irritants can cause dryness and irritation, making it difficult to wear contact lenses comfortably.
  2. High altitudes: High altitude can cause reduced oxygen levels, which can lead to eye dryness and discomfort when wearing contact lenses.
  3. Cold, dry air: Indoor heating or cold, dry air outside can reduce humidity levels and cause eye dryness.
  4. Windy conditions: Wind can also cause eye dryness and irritation, especially when wearing soft contact lenses.
  5. Water exposure: Exposure to water, such as during swimming or water sports, can increase the risk of eye infections and irritation.

If you experience discomfort or intolerance when wearing contact lenses in certain environments, it is important to speak with your eye doctor. They can recommend appropriate options, such as switching to a different type of lens or using artificial tears to alleviate symptoms. Additionally, it is important to follow proper lens care guidelines to reduce the risk of infection and improve comfort when wearing contact lenses.

Eyelid Problems:

Meibomian gland dysfunction (MGD) is a condition that affects the meibomian glands, which are the tiny oil glands located in the eyelids. These glands produce oil that keeps the surface of the eye lubricated and prevents tears from evaporating too quickly.

In MGD, the meibomian glands become blocked or damaged, which leads to an imbalance in the tear film and can cause dryness, irritation, and inflammation of the eyelids. MGD is a common condition and a major cause of dry eye syndrome.

Symptoms of MGD can include:

  1. Dry eyes
  2. Redness and swelling of the eyelids
  3. Discomfort when wearing contact lenses
  4. Blurred vision
  5. Eye irritation and a sensation of something in the eye

MGD can be treated with a combination of self-care measures and medical interventions, such as warm compresses to reduce inflammation and improve the quality of the oil produced by the meibomian glands. An eye doctor can help diagnose and recommend appropriate treatment for MGD based on the severity of the condition.

As discussed earlier, eyelid inflammation, also known as blepharitis, can be caused by several factors, including:

  1. Bacterial infections: Bacterial infections can cause inflammation of the eyelids and surrounding tissue.
  2. Allergies: Allergic reactions to pollen, dust or other environmental factors can cause eyelid inflammation.
  3. Skin conditions: Skin conditions such as eczema, psoriasis, or rosacea can affect the eyelids, leading to inflammation.
  4. Meibomian gland dysfunction: This is a dysfunction of the oil glands in the eyelids which can cause inflammation of the eyelids.
  5. Contact lenses: Use of certain contact lens solutions or wearing contact lenses for an extended period of time can contribute to eyelid inflammation.
  6. Makeup usage: Improper removal of eye makeup can lead to the accumulation of particles on the eyelids, triggering inflammation.
  7. Environmental factors: Exposure to environmental factors such as smoke, wind, sun, and air pollution can cause irritation and inflammation of the eyelids.
