Scleral lenses and traditional contact lenses both correct vision, but they differ in comfort, fit, and who benefits most.
The right choice depends on your eye health, lifestyle, and specific vision needs.
If you’re weighing your options, this blog will help you understand how scleral lenses and traditional contacts compare, what makes each unique, and how to decide which is best for you.
Understanding Scleral Lenses and Traditional Contacts
What Are Scleral Lenses?
Scleral lenses are large, rigid gas-permeable lenses that span the entire cornea and sit on the sclera, which is the white part of your eye. This design creates a fluid reservoir between the lens and your eye, offering a cushion of moisture and protection. Scleral lenses are especially helpful for people with keratoconus, irregular corneas, post-surgical eyes, severe dry eye, or other corneal surface diseases.
What Are Traditional Contact Lenses?
Traditional contacts include soft lenses and rigid gas-permeable (RGP) lenses that sit directly on the cornea. They’re widely used for correcting common vision issues like nearsightedness, farsightedness, and mild astigmatism. Soft lenses are known for their comfort and convenience, while RGPs offer crisp vision but require adaptation.
Key Differences Between Scleral and Traditional Contacts
| Feature | Scleral Lenses | Traditional Contacts |
| Fit | Vault over cornea, rest on sclera | Sit directly on cornea |
| Comfort | High, thanks to fluid cushion | Soft lenses are comfortable; RGPs less so |
| Vision Correction | Excellent for irregular corneas, advanced astigmatism, and dry eyes | Best for standard refractive errors (myopia, hyperopia, mild astigmatism) |
| Usage | Keratoconus, post-surgery, severe dry eye, corneal disease | Everyday vision correction |
| Care | Specialised cleaning solutions; more steps involved in daily care | Regular cleaning; simpler routines (especially with soft lenses) |
| Cost | More expensive | Generally less expensive |
| Stability | Very stable, less likely to dislodge | Soft lenses can shift; RGPs can dislodge more easily |
Benefits and Drawbacks of Scleral Lenses
Why Scleral Lenses Stand Out?
- Superior vision for irregular corneas: Scleral lenses are often the only option for people with keratoconus, post-surgical eyes, or significant corneal scarring.
- Comfort for dry eyes: The fluid reservoir keeps the cornea moist, making them ideal for those with moderate to severe dry eye.
- Stable fit: Because they rest on the sclera, these lenses rarely move or fall out, even during sports or active days.
- Protection: The lens provides a physical barrier that can reduce exposure to dust, wind, and allergens, which can be a relief for sensitive eyes.
Drawbacks of Scleral Lenses
- Specialised fitting: Scleral lenses require a custom fitting process and training for insertion and removal.
- Higher cost: They are more expensive than traditional contacts, both for the lens itself and for follow-up care.
- Care routine: They need special cleaning solutions and a bit more time to be cared for properly.
- Adjustment period: It can take time to get used to handling and wearing these larger lenses.
Benefits and Drawbacks of Traditional Contact Lenses
Advantages of Traditional Contacts
- Convenience: Soft lenses are easy to insert, remove, and care for, making them a popular choice for busy lifestyles.
- Affordable: Traditional contacts are generally less expensive and widely available.
- Good for standard prescriptions: They work well for correcting myopia, hyperopia, and mild astigmatism.
- Variety: Options include daily, biweekly, and monthly lenses, as well as colored contacts.
Drawbacks of Traditional Contacts
- Not for everyone: They may not work well for people with irregular corneas or severe dry eye.
- Dryness and discomfort: Some users experience dryness, especially after long hours of wear or in dry environments.
- Stability: Soft lenses can sometimes shift on the eye; RGPs may dislodge more easily, especially during sports or sudden eye movements.
- Routine care: Daily cleaning and replacement are essential to avoid infections.
Who Should Consider Scleral Lenses?
Best Candidates for Scleral Lenses
- People with keratoconus or other corneal irregularities
- Those with severe dry eye who can’t tolerate soft lenses
- Patients who have had corneal surgery or injury, such as after LASIK complications or corneal transplants
- Individuals needing stable vision for sports or active work
- Anyone who hasn’t found comfort or clarity with traditional contacts
When Scleral Lenses May Not Be Ideal?
- If you have healthy, regular corneas and a standard prescription, traditional contacts may be simpler and more cost-effective.
- If you’re not ready for a more involved care routine or frequent follow-up visits, traditional lenses might suit you better.
Who Should Consider Traditional Contact Lenses?
Best Candidates for Traditional Contacts
- People with healthy eyes and standard vision needs
- Those seeking an affordable, convenient option for daily wear
- Users who prefer disposable lenses or colored contacts
- Individuals who want a low-maintenance routine
When Traditional Contacts May Not Be Enough?
- If you have persistent discomfort, dryness, or blurry vision with regular contacts, ask your eye doctor about scleral lenses.
- If you’ve been diagnosed with an irregular cornea, traditional lenses may not provide clear vision.
Caring for Scleral and Traditional Lenses
Scleral Lens Care Tips
- Wash your hands thoroughly before handling.
- Fill the lens with non-preserved saline before insertion (as recommended by your eye care provider).
- Clean with recommended solutions after removal.
- Store in a clean, dry case.
- Attend regular follow-ups for fit and eye health.
Traditional Contact Lens Care Tips
- Wash your hands before touching your lenses.
- Clean and rinse with multipurpose solution.
- Replace lenses as directed (daily, biweekly, or monthly).
- Only sleep in your lenses if your doctor has specifically approved it. Sleeping in lenses not approved for overnight wear increases the risk of serious eye infections.
- Watch for signs of irritation or infection.
Making the Best Choice for Your Eyes
Choosing between scleral lenses and traditional contacts comes down to your eye health, comfort, lifestyle, and budget.
If you have complex vision needs or struggle with dry eyes, scleral lenses may be worth the investment and extra care. For everyday convenience and affordability, traditional contacts are a reliable choice. Talk to your eye doctor about your unique needs—they can help you find the lens that fits your life and keeps your vision clear.
Frequently Asked Questions (FAQs)
Can scleral lenses be worn all day?
Yes, many users wear them for 12–16 hours, but always follow your doctor’s advice.
Are scleral lenses hard to get used to?
They require some practice for insertion and removal, but most people adapt within a few days to a couple of weeks, depending on how often they wear them.
Do traditional contacts work for keratoconus?
Not usually. Mild cases might tolerate soft toric lenses, but scleral lenses or RGPs generally provide better vision for keratoconus.
Are scleral lenses covered by insurance?
Sometimes, especially if medically necessary for conditions like keratoconus or severe dry eye. Coverage often depends on whether the lens is considered medically necessary and how your provider codes the diagnosis.
