Wearing contact lenses has increasingly become a popular option for individuals who need vision correction.

Not only do contact lenses offer convenience and improved peripheral vision compared to traditional eyeglasses, but they also provide a more natural appearance. However, it is crucial to understand the importance of proper contact lens care to avoid potential dangers and maintain healthy eyes.

In this article, we will discuss the risks associated with improper contact lens care and provide essential tips to ensure optimal eye health.

1. Corneal Infections and Ulcers

Improper contact lens care greatly increases the risk of developing corneal infections and ulcers.

These infections, typically caused by bacteria, fungi, or parasites, can lead to severe eye pain, redness, blurry vision, and in severe cases, even vision loss. Sleeping with contact lenses, using expired contact lens solutions, and not cleaning the lenses properly are common culprits for corneal infections and ulcers.

2. Giant Papillary Conjunctivitis

Giant Papillary Conjunctivitis (GPC) is an allergic reaction that affects the inner side of the eyelids and the conjunctiva – the clear tissue covering the white part of the eye.

It is usually caused by the accumulation of protein deposits on contact lenses due to improper cleaning or extended wear. Symptoms include itching, redness, swollen eyelids, and excessive tearing. If left untreated, GPC can cause discomfort and make wearing contact lenses unbearable.

3. Dryness and Discomfort

Improper contact lens care can lead to dryness and discomfort in the eyes. Using contact lenses that are not properly cleaned or maintained can cause protein and debris to build upon the lens surface, leading to dryness and irritation.

Extended wear of contact lenses without giving the eyes a break or using the wrong type of contact lens solution can also contribute to dryness and discomfort. Chronic dryness may increase the risk of developing other eye complications and affect the overall wearing experience.

4. Corneal Abrasions

Abrasions on the cornea, the clear front surface of the eye, can occur when foreign objects come into contact with the eye.

Failure to properly clean and handle contact lenses increases the risk of introducing debris or microscopic particles onto the lens, which can irritate the cornea and lead to abrasions. Corneal abrasions can cause symptoms like severe eye pain, sensitivity to light, excessive tearing, and a feeling of something being stuck in the eye.

5. Contact Lens-Induced Acute Red Eye (CLARE)

Contact Lens-Induced Acute Red Eye (CLARE) is a condition characterized by sudden onset redness, pain, and light sensitivity caused by bacterial contamination of the contact lenses.

This condition is associated with improper cleaning and storage of lenses, as well as the use of contaminated water on lenses. CLARE requires immediate attention, as untreated cases can lead to severe inflammation and potential vision complications.

6. Contact Lens Deposits

Improper contact lens care can result in the buildup of deposits on the lens surface. Deposits commonly include proteins, lipids, and calcium deposits, which can cause blurred vision, discomfort, and reduced oxygen permeability.

Regular cleaning and proper care help prevent these deposits from accumulating and ensure optimal vision clarity.

7. Corneal Hypoxia

Corneal hypoxia refers to the condition where the cornea does not receive sufficient oxygen. Contact lenses can reduce the amount of oxygen reaching the cornea, and improper care exacerbates this issue.

When the cornea lacks oxygen, it can lead to redness, blurred vision, and discomfort. Extended wear, not following the recommended wearing schedule, and using contact lenses that don’t allow enough oxygen transmission can intensify corneal hypoxia.

8. Eye Allergies

Improper contact lens care can trigger eye allergies, causing symptoms such as itching, redness, watery eyes, and swollen eyelids.

Allergies can be the result of using expired or contaminated contact lens solutions, not cleaning the lenses thoroughly, or wearing contact lenses beyond the recommended duration. Individuals with existing allergies may be particularly susceptible to developing eye allergies due to improper lens care.

9. Contact Lens Discomfort

Failure to clean and store contact lenses correctly can lead to discomfort. Unpleasant sensations like itching, burning, or a foreign body sensation may occur due to the presence of debris or irritants on the lenses.

Additionally, using water or saliva to clean lenses or topping up contact lens solution instead of replacing it entirely can lead to discomfort and a higher risk of eye infections.

10. Poor Vision Quality

Improper contact lens care affects the performance of the lenses, ultimately leading to poor vision quality. Deposits and debris on the lenses can cause visual disturbances, such as blurred or cloudy vision.

Additionally, not storing lenses in recommended solutions or exposing them to environments with high levels of contaminants can compromise their optical quality, impacting vision clarity and sharpness.

Conclusion

Maintaining proper contact lens care is vital for preserving eye health and preventing potential dangers associated with wearing contact lenses.

By following recommended guidelines and hygiene practices, such as regular cleaning, proper storage, and adhering to wearing schedules, individuals can enjoy the benefits of clear vision without experiencing discomfort or vision-related complications.
