People trying to cut costs by buying cheap glasses online may actually be cutting corners with their health, according to a new study which has urged people to be wary of fake eyewear being sold over the internet.
Researchers from consumer champion Which? found that 15 of 36 pairs of glasses bought from online retailers were not up to standard, while four were described as "woeful".
The data, seen by the Daily Mail, found that many of the glasses did not meet recommendations for eyewear and were as such putting people's vision at risk.
Those who were behind the wheel of a car or operating machinery while wearing the glasses were not offered the necessary protection or vision correction required.
As a result, people have been urged to only buy glasses or contact lenses from reputable contact lenses with a proven track record.
Which? advised people with complex prescriptions to be very careful about who they buy from, in order to ensure they receive products of the best possible quality.
