What Are Scleral Contact Lenses?
Scleral contact lenses, sometimes referred to simply as "sclerals," are large, gas-permeable lenses that cover a significant portion of the eye's surface, including the entire cornea and part of the sclera (the white of the eye). Unlike traditional contact lenses that sit directly on the cornea, scleral lenses vault over the cornea, creating a tear-filled chamber between the lens and the eye's surface. Believe it or not, they are extremelly comfortable.
How Do Scleral Contact Lenses Work?
Improved Visual Clarity: Scleral lenses are primarily used for two main purposes: to correct refractive errors (such as myopia, hyperopia, and astigmatism) and to provide relief for certain eye conditions. The way they work is by providing a smooth, clear optical surface that compensates for irregularities in the cornea's shape. This results in improved visual acuity and reduced aberrations, offering users crisper and more precise vision.
Protecting the Cornea: Scleral lenses are particularly beneficial for individuals with corneal irregularities, such as keratoconus or severe dry eye syndrome. By creating a liquid reservoir between the lens and the cornea, these lenses provide constant hydration and protection. This not only enhances comfort but also promotes the healing of damaged corneal tissue.
Stable Fit: One of the most significant advantages of scleral lenses is their stability on the eye. Traditional contact lenses can shift or rotate during blinking, causing discomfort and inconsistent vision. Scleral lenses, on the other hand, stay firmly in place, ensuring a consistent and stable visual experience.
Customization: Scleral lenses are highly customizable to suit each individual's unique eye shape and prescription requirements. Eye care professionals use specialized equipment to measure the eye's curvature and design lenses that provide a perfect fit. This customization ensures maximum comfort and vision correction accuracy.
Protection from Environmental Factors: Scleral lenses act as a barrier between the eye and external factors, such as dust, allergens, and wind. This can be particularly beneficial for individuals with sensitive eyes or those who spend extended periods in challenging environments, such as windy outdoor activities or air-conditioned offices.
Scleral contact lenses have revolutionized the field of vision correction and eye care. They offer improved visual acuity, comfort, and protection for individuals with a wide range of eye conditions. Whether you're dealing with corneal irregularities or seeking a solution for your refractive error, scleral lenses provide a versatile and effective option.
