If you’ve ever woken up with red, irritated eyes after sleeping in your contact lenses, you could be experiencing a condition called CLARE (Contact Lens-Associated Red Eye). This common but often overlooked issue affects contact lens users—especially those who wear their lenses overnight or for extended periods.
We’ll explain CLARE, its symptoms, how to treat it, how to prevent it with better lens habits and the best daily wear and silicon hydrogel contact lenses for CLARE.
Contact Lens-Associated Red Eye (CLARE) Definition
CLARE is a non-infectious inflammatory reaction that usually occurs in people who wear contact lenses overnight or for extended wear. Although it isn’t caused by a direct bacterial infection, it is strongly associated with Gram-negative bacteria, such as Pseudomonas aeruginosa.
Wearing contact lenses while sleeping reduces oxygen supply to the cornea, creating a low-oxygen (hypoxic) environment. This allows bacteria to thrive. As they multiply, they release toxins called lipopolysaccharides (LPS), which can trigger a strong immune response. This leads to acute inflammation, primarily in the conjunctiva (the clear tissue covering the white eye) and sometimes in the cornea.
CLARE Symptoms
Symptoms usually develop quickly, often overnight. Common signs include:
- Redness of the eye (conjunctival hyperemia)
- Mild to moderate discomfort or pain
- Light sensitivity (photophobia)
- Excessive tearing
- A gritty or foreign body sensation
Contact Lens-Associated Red Eye Treatment and Prevention
If you suspect CLARE, the most important step is to immediately stop wearing your contact lenses. Continued lens use can worsen symptoms and increase the risk of complications.
Recommended treatment includes:
- Discontinue lens wear until the eye is fully healed (usually it will take a day or two)
- Use lubricating or artificial tears to soothe discomfort
- In some cases, your eye care provider may prescribe topical anti-inflammatory drops (e.g., corticosteroids) to reduce redness and inflammation
- Monitor for signs of infection since CLARE symptoms can sometimes mimic early microbial keratitis
- Resume lens use only after consulting with your optometrist or ophthalmologist
However, preventing CLARE is also better, and it is a matter of following good lens hygiene and wear habits. Here are the following tips:
- Avoid sleeping in contact lenses unless specifically prescribed and approved for overnight use
- Switch to daily disposable lenses, which reduce the risk of bacterial buildup
- Use contact lenses with high oxygen permeability, like silicone hydrogel materials
- Always wash your hands before handling lenses
- Regularly replace lens cases and avoid using tap water for cleaning
- Follow your prescribed wear and replacement schedule
- Schedule regular eye exams to monitor eye health and lens fit
Following these practices will help many contact lens wearers avoid complications like CLARE and maintain safe, comfortable vision. If symptoms such as eye redness, pain or light sensitivity occur, seek prompt professional care from an eye care professional (ECP).
Contact Lens Options That Would Help Reduce CLARE Risks
If you’re looking to upgrade to safer and more breathable lenses, here are some great options available at Lens.com:
Shop Better Affordable High Quality Daily Disposable Contact Lens at Lens.com
Daily Disposable Lenses
Daily contacts are ideal since they’re worn once and thrown away. Since each lens is fresh and sterile, there’s less chance of microbial buildup or lens case contamination. Many daily disposables like Precision1 contact lenses also use breathable materials that support better corneal health.
Silicone Hydrogel Lenses
Silicone hydrogel contact lenses allow significantly more oxygen to reach the cornea, preventing low-oxygen (hypoxic) conditions that promote bacterial growth. Their breathable design supports healthier eyes during lens wear, especially for those who wear lenses for long hours. Combined with proper hygiene, they offer a safer option for reducing inflammation-related complications like CLARE.
At www.lens.com, we have breathable contact lenses like Acuvue VITA and Air Optix Aqua contacts to help alleviate CLARE symptoms.
Prevent CLARE With The Right Habits and Lens Choices
CLARE is preventable, and with the right habits and lens choices, you can significantly reduce your risk. If you experience sudden redness, discomfort, or light sensitivity, especially after sleeping in contacts, stop lens use immediately and consult your eye care provider.
By practicing good hygiene, choosing lenses that allow more oxygen to reach your eyes, and purchasing from reliable retailers like Lens.com, you can enjoy clear, comfortable vision without the risk of red eye complications.
