BBC – Future – Does wearing glasses weaken your eyesight?.

From the May 2014 article

…A study from Nigeria published last year found 64% of students believed that wearing glasses can damage eyes. Research in the Indian state of Karnataka put the figure at 30%, and in Pakistan 69% of people feel the same way. In Brazil, even medical staff believed that your eyes would gradually get weaker as a consequence of wearing glasses. Is there any evidence to suggest they are right?

There are, of course, two very different reasons why people wear glasses – short-sightedness, or myopia, where things in the distance are blurry; and long-sightedness, or hyperopia, where you can’t focus on things close up. Long-sightedness is often age-related: many people begin noticing in their 40-50s that it’s difficult to read in low lighting. As we age the lenses in our eyes gradually stiffen, making it harder to adjust to different distances. When people get to the stage where their arms aren’t long enough to hold a book or menu far enough away to focus on the text, they opt for reading glasses.

What’s surprising is how few trials have been conducted on the prolonged effect of wearing glasses. And from what we know there’s no persuasive evidence that wearing reading glasses affects your eyesight….

In 2009 I went to Liberia with the Friends of Liberia on a 3 week service project mission.
Some of us “tagged along” with the folks from an upcountry hospital that was conducting eye checkups to teachers at three rural schools. (Unfortunately no photos of this sidetrip at the above link.)
The teachers were given eye exams and prescription glasses immediately if needed.

You might feel good sending your old reading glasses to a developing country. But a recent international study, led by the International Centre for Eyecare Education (ICEE), a collaborating partner in the Vision CRC, in Sydney, suggests it is far better to give $10 for an eye examination and a new pair of glasses if you want to help someone in desperate need, and it is far better for building capacity in these communities. ……
