What are specialty contact lenses?

Specialty contacts are small, disc-shaped lenses that you place directly over the surface of your eyes. They’re different from traditional contacts in that they use the latest technologies and are designed to treat specific vision problems, like keratoconus.

By wearing specialty contact lenses, you can improve your vision and reduce the risk of more serious problems later.

What is keratoconus?

Keratoconus occurs when your cornea –– the clear surface covering the front of your eye –– weakens and bulges outward into a cone shape. As the condition worsens, it causes blurry vision and increased sensitivity to light and glare.

Keratoconus typically affects people ages 10-25. It progresses slowly, over an extended period, and it’s easier to treat if caught early on.

When should I consider specialty contact lenses?

You might be a candidate for specialty contact lenses if you experience symptoms like:

  • Blurred vision
  • Distorted vision
  • Sensitivity to light and glare
  • A need for frequent prescription eyewear changes

You might also benefit from specialty contact lenses if you experience a sudden worsening or clouding of your vision.

How is keratoconus diagnosed?

Crystal Vision Optometry diagnoses keratoconus during an in-office visit.

Your provider reviews your medical records, asks about your symptoms and family history, and conducts a comprehensive eye exam. During the exam, they order several tests, including:

  • An eye refraction test (to check for vision problems)
  • A slit-lamp examination (to assess your cornea and to look for underlying issues)
  • Keratometry (to determine how much light reflects off your cornea)
  • Corneal topography (to create a detailed map of your cornea)

If your provider determines that you have keratoconus, they prescribe specialty contact lenses.

What are common types of specialty contact lenses?

Crystal Vision Optometry offers several types of specialty contact lenses, including:

  • Scleral contact lenses
  • Rigid gas permeable contact lenses
  • Hybrid contact lenses
  • Prosthetic contact lenses
  • Orthokeratology (ortho-k)

After an exam, your Crystal Vision Optometry provider can make recommendations that align with your needs. 

Are specialty contact lenses painful?

Specialty contact lenses are safe and usually well-tolerated. You might experience red eyes or irritation during the first few days, but your eyes should adjust quickly. If your symptoms persist or worsen, contact your provider immediately.
