How would you like to have better vision overnight?
There's a contact lens that could do the trick. Just put it in before bed, take it out in the morning... And you're on your way to perfect eyesight.
Carol Sbarge has the story.
Nya Powell plays each note clearly, thanks to her clear vision, but that wasn't always the case.
"It started to get really blurry. I couldn't really read the homework assignments and it was affecting how I played sports."
11-year-old Powell wore soft contract lens for a few years, but recently she started trying something different.
She wears a hard type lens known as a CRT lens at night, then takes them out in the morning. The lenses reshape the cornea and as a result Powell's vision is still clear for the rest of the day.
Some people sleep with them in their eyes every night. Others every other night, according to Dr. Gavin Cohen.
"Typically, depending on the prescription, the prescription will be reduced either by 50-60 percent by the next day or even 80 to 90 percent by the next day.
Dr. Cohen says the contacts corrects the power in the eye for 24 to 48 hours depending on the person.
He says it is especially good for people who have trouble wearing contact lenses during the day... for example, people with allergies.
But what Dr. Cohen says is most promising is that some recent studies show in children and teens wearing the CRT lens at night appears to stop the progression of near sightedness.
"Very attractive in patients that are progressing quickly and this is one of the only ways we know how to prevent the progression of myopia."
"It sounded very uncomfortable but I eventually got used to it and so when I'm asleep I don't feel anything."
The question is, how long before it is known how much the contacts will get someone, such as Powell, from getting worse vision?
"I think it's going to take ten years or so because in the patients as least that I'm fitting now that are 9,10,11 12 years old we won't really know their progression rates until they get older."
"Actually I think it's a great idea. It's actually a pretty amazing invention."
Doctors say Corrective Retinal Therapy is for people with low to moderate nearsightedness, as well as low amounts of far- sightedness.
The procedure is similar to getting braces, so costs depend on where you go to get it done.
