Annual lenses are durable lenses with a usability time-frame of 365 days.
This type of lens is almost exclusively reserved for coloured lenses. Though
they last a full year, they require a lot of care and attention. Clean and store
the lenses using a high-quality multi-purpose contact lens solution (don't use
peroxide!). Every 5 days, repeat the regular cleaning process and store these
lenses in a fresh solution. And don’t forget to replace the lens case in which
you’re keeping these lenses every three months. If these lenses are not
properly cared for, there is no guarantee they will remain comfortable or
healthy.
