What Is a Scleral Contact Lens Prescription?

For those who have a high prescription or a specific eye condition, wearing regular contact lenses may not be an option. That’s when scleral contact lenses come into the picture. These specialized lenses offer a solution for those who need an alternative to traditional contact lenses or glasses. Let’s dive into what a scleral contact lens prescription is and what it entails.

What Are Scleral Contact Lenses?

Scleral contact lenses are large rigid gas-permeable lenses that are designed to cover the entire sclera of the eye. They rest on the white part of the eye, not on the cornea, meaning they don’t put pressure on it. They are typically used for patients with irregular corneas, such as people suffering from keratoconus or other corneal irregularities.

Getting a Scleral Contact Lens Prescription

If you are looking to get scleral lenses, you will first need to consult with an eye doctor. The doctor will take measurements of your eye to ensure that the lenses fit properly, as well as test your vision to decide on the appropriate prescription strength. The fitting process for scleral lenses is more involved and time-consuming than regular contact lenses, so expect to have several appointments to ensure that the lenses are comfortable and effective in improving your vision.

The Prescription Itself

Just like with regular contact lenses, a scleral contact lens prescription will vary based on the patient’s individual needs. A prescription will include details such as the lens size, lens power, and base curve. Additionally, the prescription may include information about the fitting height, which is the distance between the lens and the cornea. This measurement is particularly important as it helps to ensure that the lens doesn’t move around while the patient blinks or looks around.

Why Choose Scleral Lenses?

While scleral lenses may seem like a daunting option due to their size and complexity, they offer many benefits to those who need them. These lenses are particularly useful for patients with corneal irregularities or high prescriptions, as they can offer clearer vision than traditional contact lenses. Additionally, because they don’t rest on the cornea, they don’t cause irritation or discomfort for the patient.


So, there you have it! A scleral contact lens prescription might seem intimidating, but with the right doctor and a bit of patience, it can be a great solution for those in need of specialized contact lenses. As with any new eyewear, it’s important to do your research and ask questions to ensure that you’re getting the right prescription for your eyes.
