If you’ve been told you have astigmatism, you may be wondering if contact lenses are for you. Below, you’ll find some information explaining what astigmatism is and which contact lenses are best suited for the condition.
What Is Astigmatism?
Astigmatism is a type of refractive error caused by an irregularly curved cornea. The abnormal cornea causes light to enter unevenly into the eye, which can result in blurred or distorted vision. Other common symptoms of astigmatism include eye strain, headaches, and eye irritation.
Some people are born with this condition, while others may develop it later in life.
Astigmatism typically occurs along with myopia (nearsightedness) or hyperopia (farsightedness) and can be easily diagnosed during a comprehensive eye exam.
Which Contact Lenses Can I Wear With Astigmatism?
Patients with astigmatism can still wear contact lenses, although usually not standard soft lenses. The two main options for astigmatic eyes are toric lenses and scleral lenses.
What are Toric Lenses?
Rather than having a circular surface like standard contact lenses, toric lenses have an oblong shape designed for astigmatic eyes. Toric lenses are available in both soft and rigid gas permeable (RGP or GP) lens materials.
What are Scleral Lenses?
Scleral lenses rest over the sclera (the white of the eye) and vault over the cornea (the front surface of the eye). The liquid reservoir between the lens and the cornea provides a continually moist environment that protects the cornea.
Scleral lenses have become an important therapeutic device in the visual rehabilitation of patients with astigmatism and other corneal irregularities. Scleral lenses may offer more comfort and breathability than standard soft contact lenses. They also can provide better visual acuity due to their rigid surface and customized fit. For many patients with astigmatism, scleral lenses have proven to be the optimal solution in providing long-lasting sharp and comfortable vision.

Q: Can you request lenses made from glass? Is glass still used for lenses?
- A: Yes. Opticians still sometimes use glass for lenses. However, glass is not used very often because they aren’t as safe. If these glass lenses breaks, they can shatters into many pieces and can injure the eye. Glass lenses are much heavier than plastic lenses, so they can make your eyeglasses less comfortable to wear.
Q: Can a coating be added to eyeglasses to protect them from further scratches?
- A: A protective coating can’t be added to a lens after it’s scratched. The coating is applied when the lens is manufactured and can’t be put on later.
