Can you make eyesight worse by wearing strong glasses?


I came across a website where people talk about wearing higher prescription glasses to deliberately make their eyesight worse, mainly because they like the look of coke-bottle glasses on their faces.

So, for instance, if your prescription is -2.00, you wear -3.5 for a year or so, then go for an eye test and your sight has become worse. And so on, over the years.

They say your eyesight is unlikely to get as bad as the glasses you wear, but the trick is is to always "stay ahead" slightly so that your eyes can accommodate the stronger lens, allowing you to see OK. This causes greater dependence on the stronger lens, which makes your sight worse over time. Many of those who say they do this are in their teens and twenties, simply because they like the idea of wearing strong glasses.

Quite apart from the issue of whether it is wise for young people to do this, my question is: does this work or is the idea of that you can make your sight worse by wearing strong glasses really an old wives' tale?
