With the advent of disposable contact lenses, cases of Contact Lens Acute Red Eyes (C.L.A.R.E) have been greatly reduced. With the new generation of contact lens materials, known as silicone hydrogels, extended wear contact lenses have made a resurgence. The incidence of vision last as a result from contact lens wear has been greatly reduced the chances of a patient losing vision as a result of contact lens wear, thus actually making 30 day extended wear contact lenses safer than LASIK.
Here is a good video that talks about the dangers of stretching your contact lenses.
The study comparing the safety of extended wear contact lenses vs LASIK did not restrict itself to patients that complied with the wearing schedule recommended by the contact lens manufacturer and the patient’s doctor. We find that if a patient complies with the prescribed wearing schedule then the incidence of contact lens related red eyes is very low.
Almost without exception if a patient comes in to our office with a red eye they almost always have exceeded their wearing schedule. So the moral story, discard your lenses following the prescribed wearing schedule and enjoy safe contact lens wear.
