Can i leave my contacts overnight in solution and wear glasses the next day and leave my contacts in the same solution or do i pour old solution?

Ok For One Day: Contact lenses are a major cause of eye infections. Good hygiene practices can prevent infections. Here are some pointers for safe use: 1) Wash hands before handling contacts 2) store in a clean, water tight contact solution case 3) Replace solution after each use, check solution instructions for details if not regular use 4) Cleanse case per instructions/replace old contact case every 3 months.
