The Science Behind Scleral Lenses and Tear Film Stability

Scleral lenses are designed differently than standard soft contact lenses, which is why they can be a helpful option for certain patients who struggle with dry eyes, irregular corneas, or uncomfortable vision correction. At Davich Optical in Los Angeles, we help patients understand how specialty contact lens options work and why proper fit matters for long-term comfort and clarity.
 

What Makes Scleral Lenses Different?

Traditional contact lenses rest directly on the cornea. Scleral lenses are larger and rest on the white part of the eye, called the sclera. This design allows the lens to vault over the cornea instead of sitting directly on its surface.

The space between the lens and the cornea is filled with preservative-free saline before the lens is placed on the eye. This creates a smooth optical surface and a fluid reservoir that can help support tear film stability throughout the day.
 

How Scleral Lenses Support The Tear Film

Your tear film plays an important role in clear, comfortable vision. It coats the front of the eye, keeps the surface hydrated, and helps light enter the eye evenly. When the tear film becomes unstable, vision may blur, fluctuate, or feel uncomfortable.

Scleral lenses can help by creating a protected layer of moisture over the cornea. This fluid reservoir may reduce friction from blinking and help the eye maintain a more stable surface. For Los Angeles patients who deal with dry conditions, screen-heavy workdays, or chronic irritation, this added layer of hydration can make a meaningful difference.
 

Who May Benefit From Scleral Lenses?

Scleral lenses are often considered when standard contact lenses do not provide enough comfort or visual clarity. They may be recommended for patients with:

• Dry eye symptoms that make regular contacts uncomfortable
• Keratoconus or irregular corneas
• Post-surgical corneal changes
• High prescriptions or complex vision needs
• Blurry or fluctuating vision with standard lenses

A contact lens exam helps us evaluate your eye shape, tear film, prescription, and overall eye health before deciding whether scleral lenses are the right fit.
 

Why Proper Lens Fitting Matters

The science behind scleral lenses depends on precision. If the lens does not vault the cornea correctly or align well with the sclera, it may not provide the comfort or stability patients expect. A professional fitting helps ensure the lens supports the eye without placing unnecessary pressure on sensitive areas.

At our Los Angeles office, we take time to evaluate how each lens interacts with the eye’s surface. This helps us create a better balance between comfort, tear film support, and clear vision.
 

Clearer Vision Starts With A Personalized Exam

Scleral lenses are not one-size-fits-all. Every patient’s eye shape and tear film are different, which is why a detailed contact lens evaluation is important. Whether you have struggled with contact lens comfort in the past or have been told you are hard to fit, we can help you explore your options.
