Study: Gene mutations are associated with severe form of nearsightedness

People have long taken for granted that glasses and contact lenses improve vision for nearsightedness, but the genetic factors behind the common condition have remained blurry. Now researchers at Duke Medicine are closer to clearing this up.

Exposure to daylight helps protect children from myopia

Two new studies add to the growing evidence that spending time outdoors may help prevent or minimize nearsightedness in children. A study conducted in Taiwan, which is the first to use an educational policy as a public vision health intervention, finds that when children are required to spend recess time outdoors, their risk of nearsightedness is reduced.

Wearing OK contact lenses every night can restore age-related loss of near vision

By middle age, most people have age-related declines in near vision (presbyopia) requiring bifocals or reading glasses. An emerging technique called hyperopic orthokeratology (OK) may provide a new alternative for restoring near vision without the need for glasses, according to a study, "Refractive Changes from Hyperopic Orthokeratology Monovision in Presbyopes", appearing in the April issue of Optometry and Vision Science, official journal of the American Academy of Optometry.

Study confirms rapid effectiveness of temporary, nonsurgical alternative to LASIK

A contact lens technique called overnight orthokeratology (OK) brings rapid improvement in vision for nearsighted patients. Now a new study shows that OK treatment works mainly by flattening the front of the cornea, reports a recent study, "Posterior Corneal Shape Changes in Myopic Overnight Orthokeratology", appearing in the March issue of Optometry and Vision Science, official journal of the American Academy of Optometry.

New contact lenses can cure nearsightedness, slow progression rates in children

Nearsightedness, or myopia, affects more than 40 percent of people in the U.S. and up to 90 percent of children in some parts of Asia. The problem begins in childhood and often progresses with age.

Insight into why some children develop myopia

Myopia (nearsightedness) develops in children when the lens stops compensating for continued growth of the eye, according to a study in the March issue of Optometry and Vision Science, official journal of the American Academy of Optometry.

Less incidence of nearsightedness in kids who spend more time outdoors: Study

A new study finds that children who play outdoors often are smarter, leaner and stronger than kids more inclined toward indoor activities. They're less likely to suffer from nearsightedness, in which objects in the distance appear blurry.

More exposure to natural light may reduce rates of nearsightedness

A new analysis of recent eye health studies shows that more time spent outdoors is related to reduced rates of nearsightedness, also known as myopia, in children and adolescents. Myopia is much more common today in the United States and many other countries than it was in the 1970s. In parts of Asia, more than 80 percent of the population is nearsighted.

Optical treatment strategies to correct peripheral vision may slow progression of myopia

New scientific evidence on how feedback from the eye affects visual development may lead to more effective approaches to treating myopia (nearsightedness) in children, reports a paper in the September issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

New system for optimizing eyesight

With research and development assistance from the Georgia Tech Research Institute (GTRI) and seed funding from the Georgia Research Alliance (GRA), an Atlanta-based company is developing what it hopes will be the next-generation instrument for optimizing eyesight for the hundreds of millions of people who wear glasses or contacts - or who are candidates for corrective surgery.
