Scleral lenses are special contact lenses designed to help people with conditions like keratoconus, dry eyes, or irregular corneas. They cover a larger part of the eye and hold a small pocket of saline between the lens and the cornea. This helps keep your eyes hydrated and gives you sharper, more stable vision.
If you are new to scleral lenses, you might wonder how long you can safely wear them or why they sometimes feel uncomfortable after a few hours. The truth is, everyone’s eyes are different, and the best schedule depends on how your eyes adapt, how you care for the lenses, and what your doctor recommends.
Let’s go through how to build your ideal wearing schedule, what affects comfort, and how real wearers manage their lenses every day.
Typical Scleral Lens Wearing Schedule
When you first start using scleral lenses, your eyes need time to adjust. Most eye doctors recommend increasing wear time slowly instead of wearing them all day right away. Here’s a general example of how the wearing schedule usually progresses:
- Week 1: Start with 2 to 4 hours a day.
- Week 2: Increase to 4 to 6 hours a day.
- Week 3: Try 6 to 8 hours a day if your eyes feel comfortable.
- After 3–4 weeks: You may be able to wear them for 10 to 12 hours a day.
Some people can wear scleral lenses for more than 14 hours once they’re fully adjusted, while others need to remove and refill them halfway through the day. The key is to pay attention to your comfort level, if your eyes feel dry, cloudy, or sore, take them out, clean them, and give your eyes a short break.
Factors That Affect How Long You Can Wear Scleral Lenses
Several things can influence how long scleral lenses feel comfortable and clear during the day. Knowing what affects lens performance can help you manage issues early.
Lens fit and design play a major role. A lens that’s too tight can cause redness or suction, while one that’s too loose may fog up quickly. Always follow up with your optometrist for adjustments if your lenses feel off.
If you deal with eye dryness, you may notice a white film or fogging after a few hours. Dry eyes cause tears to evaporate faster, leaving protein deposits on the lens.
A proper cleaning routine is also important. Skipping cleaning or using the wrong solution can cause buildup, which leads to cloudy vision and shorter wear time.
Your handling technique matters too. Pressing too hard or dropping the lens can cause tiny scratches that trap debris.
Lastly, the solution you use affects how long you can wear your lenses comfortably. Saline options like PuriLens, LacriPure, or Nutrifill often give better clarity than tap water or multipurpose solutions, which should never be used for filling lenses.
Why Some People Can Only Wear Lenses for a Few Hours
It’s common for new wearers to face issues like white film or fogging after a few hours of wear. This is usually caused by a buildup of protein, mucus, or lipids from your tears inside the lens reservoir. Sometimes it happens because the lens fit is too tight or the saline you’re using isn’t the best match for your eyes.
If fogging or white buildup is blocking your vision after 3–4 hours, try these helpful tips shared by experienced wearers and eye specialists:
- Use lubricating drops throughout the day to keep your eyes hydrated.
- Remove, rinse, and reinsert your lenses mid-day if vision becomes cloudy.
- Try PuriLens or LacriPure saline instead of tap or multipurpose solutions.
- For very dry eyes, use Systane or Nutrifill drops before and after wearing your lenses.
Once your eyes are properly hydrated, the buildup usually reduces, and you can extend your wear time gradually.
Difficulty Removing Scleral Lenses
Many new wearers struggle with removing scleral lenses, especially from one eye more than the other. This happens because scleral lenses form a gentle suction on the eye to stay in place. If your lens feels stuck or your eye gets red after removing it, you’re not alone, almost every new user goes through this stage.
Here are some proven removal tips that make the process easier and safer:
- Always use the small plunger for removal.
- Place the plunger slightly off-center at the 4 o’clock or 6 o’clock position to break suction easily.
- Put a drop of saline on the plunger before use, it helps create a better grip.
- If the lens feels tight, apply a few drops of lubricating solution, wait a minute, and try again.
Some long-time wearers remove their lenses without plungers. They gently lift the upper eyelid under the lens edge to let air in and break the seal. However, this technique takes practice and should only be tried after you’re completely comfortable handling your lenses.
Mild redness after lens removal is normal due to temporary suction. But if you notice bright red marks or pain, it might mean your lens fit needs adjustment.
Real Experiences from Long-Term Scleral Lens Wearers
Many people have shared how their wear time and comfort improved as they learned proper care and handling.
Some wearers who initially could only wear lenses for 3 to 4 hours a day managed to extend that to 6 or more hours after finding the right saline and cleaning routine. Regular cleaning with Clear Care or deep-cleaning treatments like Menicon Progent helped remove protein buildup and restore clear vision.
Others have reported being able to wear their scleral lenses comfortably for 10 to 12 hours each day once their eyes have adjusted. People with very dry eyes often use punctal plugs and hydrating drops, which help reduce fogging and extend wear time.
A few users even shared that they had worn the same pair for several years with consistent cleaning, lens polishing, and yearly checkups. Proper care made their vision stable and lenses long-lasting.
However, some noticed that after about four years, their lenses became slightly uncomfortable or cloudy. Eye doctors explained that this was normal wear for certain lens materials and recommended replacement or polishing.
These stories show that patience, good hygiene, and regular checkups can make a big difference in comfort and lens life.
When to See Your Eye Doctor
Even with good care, you may experience redness, irritation, or fogging at times. If your eyes stay red after removing lenses or if your vision remains cloudy no matter how often you clean them, it’s best to schedule an appointment.
Persistent discomfort may mean:
- The lens fit is too tight or too loose.
- Protein deposits are building up on the lens surface.
- Your cornea’s shape has changed slightly over time.
Eye specialists can polish or refit your lenses, recommend new solutions, or adjust your wearing schedule to improve comfort.
Tips for Building a Healthy Wearing Routine
Maintaining a healthy wearing routine is essential for keeping your scleral lenses clear, comfortable, and long-lasting. Small daily habits can make a big difference in preventing irritation and lens damage. A consistent routine helps your eyes adjust better, reduces fogging, and ensures each wear feels as comfortable as the first.
- Start with short wear times and increase gradually.
- Always wash and dry your hands before touching lenses.
- Clean lenses daily using recommended solutions.
- Avoid tap water at all costs.
- Store lenses in fresh disinfecting solution each night.
- Replace saline solution for every fill — don’t reuse it.
- Take short breaks if your eyes feel dry or tired
A good routine not only improves comfort but also protects against infection and helps your lenses last longer.
How Long Can You Safely Wear Scleral Lenses?
Once your eyes adapt and your lenses fit well, most people can wear scleral lenses for 10 to 14 hours per day without problems. Some even manage longer hours, but doctors generally recommend giving your eyes some rest time daily.
If you notice any of these warning signs, remove your lenses right away:
- Pain or stinging sensation
- Sudden cloudy vision
- Persistent redness
- Excessive tearing or dryness
Ignoring these symptoms can cause irritation or infection, so always err on the side of caution.
Final Thoughts
Wearing scleral lenses can be life-changing for people with keratoconus, dry eyes, or other corneal issues, but comfort comes with care and patience. Building up your wear time slowly, using the right solutions, and cleaning lenses properly all play a major role in keeping your eyes healthy.
Once you develop a good routine, you’ll likely find your lenses comfortable for the entire day with clear vision and minimal fogging.

Frequently Asked Question
How long can I wear scleral lenses each day?
Most people can wear scleral lenses for 8 to 14 hours daily. It’s best to start with a few hours and slowly increase the time as your eyes adjust. If your eyes feel dry or tired, remove them and give your eyes a short rest.
Is it normal to feel pressure or redness after removal?
Yes, mild pressure or redness is normal, especially for new wearers. The lens rests on the white part of your eye, which may leave a temporary mark. However, if the redness or discomfort lasts a long time, you should contact your eye doctor.
What is the white film that forms after a few hours?
That’s called mid-day fogging, a common issue with scleral lenses. It happens when debris or tear buildup clouds your vision. Removing the lens, rinsing it, and refilling it with fresh saline usually solves the problem.
Can I sleep in scleral lenses?
No, sleeping in scleral lenses is not recommended. Your eyes need oxygen and moisture during rest, which lenses can block overnight. Always remove them before bed to avoid dryness or possible infections.
What helps if a lens gets stuck?
If your scleral lens feels stuck, use lubricating drops to loosen it. Gently use the small suction plunger on the lower edge to lift it off. Never pull or force the lens—if it won’t come out, call your optometrist for help.
