Why do I have to trash my contacts every month?!
Question: contacts for the eyes, not the phonebook lol
Answers: contacts for the eyes, not the phonebook lol
Your eye ball needs air, your contact needs to be able to breathe to get air to the eye surface. Over the course of time the contact will collect and fill up with gunk and thus stop breathing. Since every person and their environment is different they have chosen one month for your contacts for changing. There is a certain amount of safety factor built in, but don't mess with that. Just go ahead and change them every month and it will help keep your eyes healthy.pp
Because they collect proten residue from your tears. Most disposables have to be disposed of regularly, but hard contacts last forever.
Because the lenses will expired after one month when expose to air.
