What Are Scleral Lenses and How Do They Differ from Glasses?

Scleral lenses are large, gas-permeable contact lenses that vault over the cornea and rest on the sclera (the white part of the eye). These lenses differ from glasses in their design, function, and suitability for various vision conditions.

Design: Scleral lenses are larger than standard contact lenses and cover a larger surface area.
Function: Scleral lenses create a tear-filled reservoir, improving vision by providing a smooth optical surface for irregular corneas.
Comfort: Scleral lenses can offer increased comfort for individuals with specific eye conditions, where glasses may not suffice.
Conditions Treated: Scleral lenses are often used for conditions like keratoconus, severe dry eye, and corneal irregularities, while glasses typically address standard refractive errors.
Maintenance: Scleral lenses require a different cleaning and fitting regimen compared to glasses.

These points highlight the unique aspects of scleral lenses compared to traditional glasses. Understanding each of these attributes can help individuals make informed decisions about their vision correction options.

Design:
Designing scleral lenses involves creating larger structures that cover the cornea and rest on the sclera. These lenses are custom-made for each individual’s eye shape and size. Their larger diameter makes them less likely to induce discomfort or displacement. A study by Kinoshita et al. (2020) found that the unique design of scleral lenses can significantly improve visual acuity in patients with irregular corneas. In contrast, glasses have a fixed size and shape, relying solely on refraction through lenses that are positioned in front of the eyes.
Function:
Scleral lenses serve a functional purpose beyond vision correction. They create a reservoir of tears between the lens and the cornea, which can provide hydration and comfort for dry eye sufferers. This functionality is particularly beneficial for conditions like keratoconus, where the cornea is misshapen. Research from the American Academy of Ophthalmology states that scleral lenses can be effective for managing ocular surface disease by protecting the cornea from environmental factors. Glasses do not provide this benefit, as they do not come into direct contact with the eye.
Comfort:
Comfort varies significantly between scleral lenses and glasses. Many people with eye conditions like severe dry eye or corneal irregularities find scleral lenses more comfortable than glasses. According to a study by Jun et al. (2019), participants reported high levels of comfort with scleral lenses, attributing it to the cushioning effect created by the tear reservoir. Glasses may cause pressure points on the nose and ears or may not provide adequate relief for individuals with specific eye issues.
Conditions Treated:
Scleral lenses treat various eye conditions more effectively than glasses. They are often prescribed for keratoconus, post-surgical patients, and other conditions that lead to irregular corneal shapes. In contrast, glasses primarily correct standard refractive errors, such as nearsightedness or farsightedness. Research published by the Journal of Optometry and Vision Science (2021) indicates that patients using scleral lenses have a better quality of life due to enhanced visual performance and decreased symptoms associated with their eye conditions.
Maintenance:
The maintenance of scleral lenses diverges from that of glasses. Scleral lenses require specific cleaning solutions and a routine to ensure they remain hygienic and functional. Proper care is essential to prevent complications such as infections. Conversely, glasses require minimal maintenance, primarily cleaning their lenses. According to the American Academy of Ophthalmology, the extra considerations for caring for scleral lenses can be a drawback for some users, making glasses a more convenient option.

These differences highlight the advantages and potential challenges of scleral lenses compared to glasses, enabling individuals to choose the best option for their vision needs and lifestyle preferences.
