Monthly contacts have a wearing period of 30 days. Because
of this longer wearing time, they need to be cleaned and stored in a cleaning solution for at
least 8 hours after use each day. They must not be worn longer than one
month. If you are considering monthly contact lenses, it’s important to
remember monthly lenses present a slightly higher risk for people with very
sensitive eyes, compared to daily contact lenses. But, for normal users, the
benefit of monthly contact lenses is that they are the cheapest
option for everyday wear and can be safe and comfortable with proper
care, handling, and storage.
