A new study found that many contact lens wearers in the United States do not follow the recommended replacement schedules for their lenses, making them vulnerable to a variety of eye infections, which cause serious eye problems.
The study examined 1,654 contact lens wearers in groups with different replacement frequency. It found that people wore their contact lenses for a much longer period of time than recommended and didn’t replace contact lens case in time:
- 26 % of those who over-wore their lenses said they wanted “to save money” by wearing their contacts for longer periods
- 51 % said they “forgot which day to replace their contact lenses”
- 18 % of participants reported it was “not important” to clean contact lenses every day
- 16 % of contact lenses wearers replaced their contact lens case only once a year
- 14 % never replaced their lens case

To counter these problems, researchers have been studying the use of contact lenses to deliver eye medication.
