Contact lenses have for years been offering people relief from eye problems and they increase in popularity every single year. Though in the vast majority of cases, they only offer a temporary solution to permanent eye conditions, no matter how effective they are.
However, a new type of contact lens is giving people the opportunity to free themselves from restrictive eye conditions forever.
Corneal Refractive Therapy (CRT) lenses have been developed as an alternative to laser eye surgery, but they perform the same task namely, resolving eye problems such as nearsightedness and astigmatism.
A recent report by My Fox Atlanta examined the effect the lenses had on two teenagers who were too young for laser eye surgery and so decided to give CRT contact lenses a try.
The products work by exerting pressure on the eyeball to correct certain eye conditions gradually, without disrupting the wearer"s everyday life, and they are worn overnight.
Atlanta optometrist Dr David Sweeney, who was an early adopter of CRT lenses, told the source that he had no doubts about prescribing the lenses to 15-year-old Freddy Hart and 16-year-old Andrea Pascual.
"CRT is a unique lens that corrects nearsightedness and astigmatism and you wear it at night as opposed to during the day," he explained.
"So you put it in when you go to sleep and gentle lid pressure changes the shape of the eye and in the morning you take it off and you see clearly all day long without glasses or daytime contact lenses."
His two patients have benefited from great vision after using the lenses, with Andrea saying she noticed the difference after a couple of days and can now see clearly without the need for vision correction.
Dr Sweeney added that he now intends to expand the prescription of the lenses to more patients so they can benefit from clear eyesight without the need for glasses.
