(KAIT/NBC) - If your vision isn't 20-20, you might be able to wear glasses or contacts to correct your vision.
However, people with a disease called Keratoconus cannot correct their vision the conventional way. Keratoconus is rare with fewer than 200,000 cases in the U.S. per year.
Erica Reed suffered for years before she was finally diagnosed.
Unfortunately, there aren't many ways to correct the disease. For Reed, she had no idea how bad her vision was until she got specialized contacts to help curve it.
Dr. Charles Thompson says, for now, Reed's contacts are the only way she can function through life.
"From the mild cases to the severe cases you're looking at different types of specialized contacts to kind of maximally correct vision."
Insurance doesn't cover surgery or cornea replacement for the disease. In 2019, however, a procedure to stabilize the vision and the disease will be covered under some plans.
