WASHINGTON 鈥� It鈥檚 that time of year when books replace beach vacations and pop-quizzes trump Popsicles. But heading back to school can be a difficult time for students who have difficulty seeing the board.
According to the , more than 40 percent of the country is myopic 鈥� or nearsighted. This means close objects appear clearly, but objects in the distance are blurry.
And this condition, which typically starts in childhood, is getting worse.
Since the 1970s, the rate of nearsightedness in Americans 12 to 54 years old has increased by nearly two-thirds. In Asian countries, the progression is even more alarming. Eighty to 90 percent of teens and young adults in China are nearsighted, . 聽
For decades, myopia has been corrected with the same conventional approach: prescription glasses or contact lenses. But now, there鈥檚 an option for parents who don鈥檛 want to keep taking their child back to the eye doctor for thicker lenses each year as their vision worsens.
, a new eye care center with locations in Bethesda, Maryland, and Vienna, Virginia, offers treatments to stop the advancement of myopia in children.
Gary Gerber, an optometrist and co-founder of Treehouse Eyes, said聽聽it鈥檚 not just about ditching glasses. Treating myopia early is key to avoiding serious complications later in life.
鈥淚f it goes unchecked, if it gets worse and worse and worse, the kids are going to be at higher risk for retinal diseases, glaucoma 鈥� which can have sight-threatening, life-changing serious consequences beyond needing stronger glasses,鈥� he said. 鈥淭he more myopic you become, the higher risk you are to have these problems.鈥�
Gerber, who has been working in the eye industry for more than 20 years, said聽myopia is diagnosed as early as 6 years old 鈥� right about the time when seeing a blackboard or whiteboard at school becomes part of the daily routine.
Those with myopia have an elongated eyeball, causing light rays to focus at a point in front of the retina, rather than directly on its surface. Typically, glasses are prescribed to correct the blurry vision 鈥� but Gerber said聽that鈥檚 a Band-Aid approach.
鈥淲hen you put on a pair of glasses, you can see better far away, but you鈥檙e still myopic and your eye is going to continue to get worse,鈥� he said.
At Treehouse, specialists use one of three options to stop a patient鈥檚 myopia from getting worse. The first is an eye drop, which is applied at night. Andrew Morgenstern, optometrist and clinical director at Treehouse Eyes, said聽the drops are atropine in a dilute concentration.
The second treatment is a hard contact lens, called orthokeratology lenses.
鈥淭hey put it in right before bed, they sleep in it, they take it out in the morning,鈥� Morgenstern said.
The third is a soft lens, constructed with curves and ridges like the hard lens, that is worn during the day.
鈥淭he goal of this is to create a de-focus, a little bit of a specialized type of light coming into the eye through that specific contact lens to focus light at the right place, so that we can actually use that to halt the progression of nearsightedness,鈥� Morgenstern explained.
A quick exam at Treehouse determines which option is best for the patient, and most treatments are used until the eye is done growing 鈥� at聽17 or 18 years old. Morgenstern said聽to think of the drops or the lenses like a retainer.
鈥淲e鈥檙e trying to hold something in place up until the point where it鈥檚 not going to change any more,鈥� he said. 鈥淥nce we get the eye to the point where it鈥檚 not growing anymore, then we鈥檙e in really good shape.鈥�
The Treehouse treatments are not covered by insurance, and Gerber predicts it will be a while before that happens. The cost is a flat $2,800, which Gerber said聽is less expensive than paying for more serious complications that can arise from myopia, such as聽retina surgery.
Both of William Ni鈥檚 sons, Andrew and Aaron, were diagnosed with myopia when they were in the third grade and both were fitted for glasses.
鈥淲e didn鈥檛 know of any other options,鈥� said Ni, of Fairfax, Virginia. 鈥淚 wore glasses most of my life, my wife did as well.鈥�
At the time, they were living in California, and a friend told them about the option for orthokeratology lenses. They tried it out, and ended up liking the treatment option for its convenience.
鈥淭hey don鈥檛 have to wear glasses during the day, and they do a lot of activities,鈥� Ni said.
Now Ni’s sons are 15 and 17.
鈥淭he best thing is that their vision hasn鈥檛 worsened. Other kids get thicker glasses; that鈥檚 not the case with my sons.鈥�
Other eye doctors, like Ni鈥檚 California-based optometrist, in recent years, but Gerber says no other center focuses solely on myopia treatment. Unlike other eye centers, there isn’t a wall full frames and a person fitting lenses in the office.聽That鈥檚 what makes Treehouse unique 鈥� and needed.聽
An estimated 10 million children聽in the U.S. have myopia, and research suggests that number is going to continue to increase.
Digital device use and lack of natural light are thought to be contributors to the disease. A 2015 study published in the found that children who spent 40 minutes more time outdoors were less likely to develop myopia.
鈥淲e鈥檙e hunters and gatherers and we do best and our eyes are healthiest when we look off in the distance,鈥� Gerber said. 鈥淎nd there鈥檚 nothing in this room that鈥檚 longer than 20 feet.鈥�
