Nearly one in five (18pc) pairs pairs of prescription glasses could be putting people at risk of driving illegally or falling over, eye experts have warned, with spectacles bought online posing a heightened safety risk to consumers.
A damning study on the quality of glasses sold in the UK, funded by the College Optometrists, has warned prescription glasses wearers going online in search of a cheaper deal that they may be more exposed to dangers caused by poor vision.
The College (of) Optometrists being largely those who do not sell on line of course.
The major difficulty seems to be pupillary distance. And from memory it’s difficult to get a optometrist, who has just charged you for an eye test, to put the pupillary distance on the prescription.
When people order in store an optician usually measures their their pupilary distance using specialist equipment. But when glasses are purchased online the measure is usually supplied by the customer, which leads to inaccuracies.
Insist that that distance is put on the prescription, as with the other information then.
