Many people are wearing their contact lenses for too long, according to a new survey.
Many people are leaving their contact lenses in their eyes for longer than they should do, new research has found.
The poll of 1,654 wearers of contact lenses was headed by David Sarwer and commissioned by Ciba Vision, reports the Daily Pennsylvanian.
It found that most (59 per cent) of people wearing two-week silicone hydrogel contact lenses were using them for too long while the same was true of 29 per cent of one-month lens users and 15 per cent of those with daily disposable lenses.
The biggest reason for this was forgetting the use-by dates, given by 51 per cent of people, though 26 per cent do it as a cost-cutting measure.
Similar results were found recently in a study by the Centre for Contact Lens Research at Canada"s University of Waterloo.
It found that 40 per cent of people do not replace their contact lenses by the date they should do.
