Adjustable glasses for poor countries
Published: Wednesday 2nd February 2011

The use of inexpensive adjustable eyeglasses is an effective technique to treat vision problems in adolescents living in poor countries, a new study says.

Refractive error has particular effects on school-going children as the inability to see can impair his/her learning capabilities and career prospects.

Considering the shortage of eyeglasses in the developing nations, scientists say the use of adjustable eyeglasses called Adspecs has brought a chance for people in remote and poor areas to tackle their problem while paying less.

Adspecs, invented by Joshua D. Silver -- a physicist at Oxford University, allows users to correct their own vision and thereby overcomes the need for expensive equipment or eye-care specialists.

According to the findings of the study conducted by Silver et al, more than 92 percent of the children are able to correct their nearsightedness using the glasses, which was just 8 percent less than those received professional eye exams.

The adjustable glasseshave special lenses made of a clear membrane filled with silicon oil and held between two plastic discs.

The wearer can change the curvature of the lenses and their strength through adding or removing the oil in the lenses using a removable syringe and dial attached to the frame.

Adspecs, which have a big frame, cannot correct certain eye problems such as astigmatism.
