Scleral lenses typically last between one and three years, though individual wearers may require earlier replacement depending on corneal changes, lens condition, or visual needs.
Proper maintenance and consistent cleaning are essential to prolonging their lifespan and ensuring sustained comfort.
Understanding the longevity of scleral lenses begins with knowing the factors that influence their durability. From material quality and daily cleaning routines to frequency of wear, many aspects determine how long these speciality lenses will remain in optimal condition. This blog will explore these details in depth, helping you make the most of your lenses.
Factors That Influence the Lifespan of Scleral Lenses
Quality of Materials and Manufacturing
The durability of scleral lenses heavily depends on their construction material. High-quality lenses are made of rigid gas-permeable (RGP) materials, designed to withstand daily use. These materials are not only robust but also promote healthy oxygen flow to the cornea, reducing the risk of complications over time.
Modern advancements in RGP technology ensure that scleral lenses:
- Resist scratches
- Maintain optical clarity
- Provide enhanced comfort
However, not all lenses are created equally. Customised lenses, tailored to the unique shape of the wearer’s eye, often outlast generic options.
Frequency of Use
How often you wear your scleral lenses also impacts their longevity. Daily wear naturally exposes lenses to more wear and tear, requiring consistent maintenance. Conversely, those who wear lenses occasionally may notice their lenses last longer. However, infrequent use does not excuse lack of upkeep.
Cleaning and Maintenance Routine
Proper hygiene can significantly extend the lifespan of scleral lenses. Regular cleaning removes protein deposits, bacteria, and other contaminants that could compromise the material and comfort. Essential care best practices include:
- Daily Cleaning and Disinfection: Use cleaning systems designed for gas-permeable or scleral lenses—typically either a hydrogen peroxide-based system or a dedicated RGP lens cleaner. Avoid multi-purpose solutions made for soft lenses, as they may not disinfect properly and can leave residue.
- Rinsing and Storing: Always store lenses in specialised solutions. Do not use tap water, as it can introduce harmful microorganisms.
- Replacing Lens Case: If you use a hydrogen peroxide cleaning system, replace the case every time you start a new bottle of solution—usually monthly.
Skipping these steps, even occasionally, can shorten the effectiveness and life of the lenses.
External Environmental Factors
Your environment plays a critical role in the durability of scleral lenses. Prolonged exposure to dusty, polluted, or high humidity settings can cause deposits to form on the lens surface, thereby reducing its clarity and comfort. Individuals working outdoors or in challenging environments should take extra precautions, such as protecting lenses with preservative-free drops or protective glasses.
Additionally, resting in environments with improper ventilation (e.g., air-conditioned rooms for extended periods) can lead to dryness, impacting both comfort and functionality of the lenses over time.
Signs That It’s Time to Replace Your Scleral Lenses
Even with the best care, scleral lenses will eventually need replacing. Knowing the signs of lens deterioration is key to protecting your eye health. Watch out for the following indicators:
- Scratches and Surface Damage
Small imperfections on lenses can affect vision quality and comfort. Inspect your lenses regularly for visible wear.
- Reduced Optical Clarity
If you notice blurriness that cleaning cannot fix, your lenses may no longer provide their original vision correction. Residue build-up or microscopic fractures in the material can cause decreased visibility.
- Discomfort or Irritation
Discomfort such as redness, itchiness, or a feeling of grit in the eye may indicate that your lenses are wearing down or fitting poorly.
- Frequent Breakages
If lenses crack or chip more easily, it’s a sign that the material has weakened over time.
If you notice any of these signs, consult your eye care provider to determine whether it’s time for a replacement.
Best Practices to Extend the Lifespan of Scleral Lenses
To make your scleral lenses last their full intended lifespan, follow these proven care tips:
Stick to the Recommended Replacement Schedule
Your eye care specialist will provide a specific replacement schedule tailored to your prescriptions and lens type. Even if your lenses seem fine, adhering to this schedule helps prevent subtle wear issues and avoids lasting damage to your eyes.
Be Gentle During Handling
Scleral lenses are durable but not indestructible. Avoid using excessive force when inserting, removing, or cleaning them. Instead, use gentle, circular motions during cleaning, and avoid rubbing the lens surface too vigorously.
Avoid Using Water on the Lenses
Never expose scleral lenses to water, whether it’s tap, bottled, or distilled. Water can contain harmful microorganisms that cause severe eye infections.
Avoid Skipping Follow-Up Appointments
Routine check-ups with your eye care provider ensure your lenses fit properly and remain in good condition. They can spot potential issues early and suggest adjustments if needed.
Use Preservative-Free Lubricating Drops
Only use preservative-free lubricating drops labeled as safe for use with scleral lenses or with contacts. Avoid drops with preservatives unless advised by your eye care provider.
Protect Lenses When Not in Use
If you plan to switch between wearing lenses and glasses during the day, always store your lenses in a dedicated lens case filled with the appropriate disinfectant solution.
Are Scleral Lenses Worth the Maintenance?
While scleral lenses require a bit more maintenance than soft lenses, their long-term benefits, particularly for individuals with specific eye conditions, make them an invaluable investment. They are especially effective for people with:
- Keratoconus or other irregular corneas
- Severe dry eye syndrome
- Corneal scars or post-surgical needs
Scleral lenses offer unparalleled comfort and sharp vision correction that many cannot achieve with soft or hybrid lenses. Proper care ensures you make the most of this premium solution while safeguarding your eye health.
Final Thoughts on the Lifespan of Scleral Lenses
Understanding how long scleral lenses last ensures you maintain optimal eye health while maximising their value. With proper care and regular monitoring, these lenses can last up to three years, providing exceptional clarity and comfort throughout their lifespan.
If you’re considering scleral lenses or currently using them and want advice on care routines, consult your optometrist or eye care provider. Maintaining routine appointments and adhering to care guidelines is the best way to enjoy their incredible benefits, further extending their life.
Proactive care isn’t just about saving money; it’s about ensuring your eyes remain healthy and happy in the long run.
