Coloured contact lenses - Quarterly
Quarterly lenses are durable lenses with a usability time-frame of 90 days. This type of lens is something you'll usually see among coloured lenses. They are very cost-effective but require a higher degree of maintenance and care. If they fall within the category of coloured lenses, it's commonly assumed you won't be wearing them every day during their 90-day lifespan and that'll you'll carefully clean, disinfect, and store them. If they fall under the category of normal contact lenses, they should be specifically prescribed by an eye care specialist. With lenses that need extra care -e.g. quarterly lenses - be sure to always follow the instructions of your eye care specialist.
