Scleral Lenses Mean Comfortable Contacts for More Patients
Contact lenses are a great option, giving you the chance to go through your day with clear vision and without glasses. Unfortunately, a lot of people don’t think they can wear contact lenses, either because they find them uncomfortable, or because they’ve been told their eyes are too hard to fit.
The truth is that contact lenses may still be an option for you. It’s all a matter of finding the right contact lenses. We’re excited to offer scleral lenses, which fit and function slightly differently from standard contact lenses.
Benefits of Scleral Lenses
- More comfortable than regular contacts in some cases
- More stable than regular contacts
- They usually don’t touch the cornea
- They help regulate issues caused by an uneven corneal surface
- They help keep the eye hydrated
- Decreased sensitivity to light

What Are Scleral Contact Lenses?
Scleral contacts are a special type of contact lenses that, simply put, cover more of the eye. Standard contact lenses cover the surface of the cornea. Scleral lenses, on the other hand, extend past the edges of the cornea to the sclera (the medical term for the white part of your eye.)
Who Benefits From Scleral Lenses?
Lots of patients have tried contact lenses in the past but found them too uncomfortable or difficult to wear. Scleral contact lenses offer extra stability and a higher level of comfort in many cases. These special lenses may be a particularly good option for patients who’ve been told their eyes are “difficult to fit” or that they have a condition that prevents them from wearing contact lenses.
Standard contacts can aggravate an extreme case of dry eye, making them almost unbearable to wear.
Scleral lenses leave a space between the surface of the cornea and the lens which acts like a reservoir, preventing moisture from evaporating and keeping the eye hydrated throughout the day.
Astigmatism is a refractive error caused by an irregular eye shape. Not only does this impact vision, but it makes contact lenses rotate, causing fluctuations in vision.
Scleral lenses are great for astigmatism because they’re more stable than regular contacts.
A typical cornea has a uniform thickness, with a consistent curve over the surface. When the cornea starts to thin and bulge outwards in the centre, it’s called keratoconus.
Because scleral lenses vault over the cornea rather than actually touching it, they’re perfect for correcting corneal abnormalities like keratoconus. The uniform curve of the lens essentially acts the way a typical cornea would, focusing light at a single point on your retina for clearer vision.
