Scleral lenses, also known as scleral contact lenses, are large-diameter contact lenses that vault over the entire sclera (the white part of the eye). They offer a unique solution for various eye conditions, providing comfort and improved vision. But a common question arises: how long do scleral contacts last? The answer isn't straightforward and depends on several factors. Let's delve into the details.
How Long Can I Wear My Scleral Lenses Each Day?
The wearing schedule for scleral lenses is determined by your eye doctor based on your individual needs and the lens material. Some individuals can wear them for extended periods, even overnight, while others might need to remove them daily. This is crucial: never extend your wearing time beyond what your optometrist recommends. Improper wear can lead to serious eye complications.
How Often Do Scleral Lenses Need to Be Replaced?
This is where the lifespan of your scleral lenses truly comes into play. Unlike daily disposable contacts, scleral lenses are not disposable in the same way. They typically last for one to two years, but this is just an average. Several factors affect their lifespan:
- Material: The material of your scleral lenses plays a significant role. Different materials have varying durability and resistance to damage.
- Cleaning and Care: Proper cleaning and disinfection are paramount. Failure to follow your eye doctor's instructions meticulously will shorten the lifespan of your lenses and increase the risk of infection.
- Wear and Tear: Daily use, even with careful handling, can lead to gradual wear and tear. Microscopic scratches and deposits can accumulate over time, impacting lens clarity and comfort.
- Individual Eye Health: Certain eye conditions or lifestyle factors might affect the longevity of your lenses.
What Factors Influence the Lifespan of My Scleral Lenses?
Let's break down the factors influencing how long your scleral contacts last in more detail:
Material of the Lens:
The material from which your lenses are made directly impacts their durability. Some materials are more resistant to damage and deposits than others. Your eye doctor will recommend a material based on your specific needs and eye condition.
Proper Cleaning and Disinfection:
This is arguably the most important factor. Failing to clean and disinfect your scleral lenses correctly can lead to bacterial growth, irritation, and significantly reduce their lifespan. Always follow your eye doctor's meticulous instructions regarding lens cleaning, rinsing, and storage solutions.
Wear and Tear from Daily Use:
Even with the best care, daily use will eventually cause wear and tear. Microscopic scratches can accumulate, affecting the clarity and smoothness of the lens surface. This gradual degradation can impact comfort and vision.
Individual Eye Health and Lifestyle:
Your overall eye health and lifestyle habits can influence the lifespan of your lenses. Certain eye conditions or environmental factors (like dust and pollution) can contribute to faster deterioration.
How Often Should I Visit My Eye Doctor for Scleral Lens Checkups?
Regular checkups with your eye doctor are vital. They will assess the condition of your lenses, check for any signs of damage or infection, and determine if replacement is necessary. Typically, you'll need checkups every three to six months, but this frequency might vary depending on your individual circumstances.
Can I Extend the Lifespan of My Scleral Lenses?
While you can't significantly extend the inherent lifespan determined by the material and manufacturing process, meticulous care and regular checkups can help you maximize the time you can safely and comfortably use your lenses.
What are the Signs My Scleral Lenses Need Replacing?
Several signs indicate it's time for new scleral lenses:
- Decreased Comfort: Persistent discomfort, irritation, or blurry vision despite proper cleaning.
- Visible Damage: Cracks, scratches, or significant deposits on the lens surface.
- Change in Fit: A noticeable change in how the lenses fit or feel.
- Your Eye Doctor's Recommendation: Your optometrist's professional judgment is crucial. They can detect subtle issues that you might not notice.
In conclusion, the lifespan of scleral lenses is variable and depends on several factors. Regular checkups with your eye doctor, meticulous cleaning and disinfection, and careful handling are key to ensuring the longevity and safety of your scleral contact lenses. Remember, prioritizing eye health is paramount.
