Anyone who wears glasses and uses a computer
is often presented with the availability and options of buying their eyewear
online. When asked, most people say they are interested in internet eyeglass
purchases because it seems to be convenient. Many others say it’s because they
can get a good deal A recent study in the journal Optometry & Vision Science compared the overall quality and fit of eyeglasses bought online with eyewear
purchased from from optometry practices. The study found that patients
preferred spectacles bought from optometry practices rather than those bought
online, in spite of lens quality and prescription accuracy being similar. A
greater number of online spectacles were deemed unsafe or unacceptable because
of poor spectacle frame fit, poor cosmetic appearance, and inaccurate optical
centration. This appears to especially be the case for Progressive Addition Lenses
(PAL) or “Progressives” as when these lenses are not fit and positioned
properly they can cause a great deal of unusual distortion and discomfort.
