False economy in more ways than one?

One in four pairs of prescription glasses bought online could be putting people at risk of driving illegally or falling over, eye experts have warned. A study on the quality of glasses sold in the UK, funded by the College of Optometrists, found that of 154 pairs bought online, 43 (27%) were found to be unacceptable when tested. It's always better to visit an optometrist who knows your vision history and needs.
