How often to you have to renew your eyeglasses prescription?

Answer 1

It depends on what kind of contacts and the amount given. Usually, for a "one month" pair, it'll be usually about six months per prescription, or six contacts per case.

Usually contact lens prescription is good for one year. After the year from when you had your eyes exam, the office or you yourself can make another exam to see if you can still see in your current prescription.

Answer 2

More frequently you change your contact lenses, more healthier and comfortable your eyes are.

Depending on the contact lenses, there can be disposable lenses and traditional lenses.

Disposable lenses can be replaced every 2 weeks or so.

Traditional lenses can be replaced every 6 months or longer.

Answer 3

How often you should replace your contact lenses all depends on what kind of lenses you have.

Disposable lenses are replaced more often, so there is less time for bacteria and other things to gather on them.

Some people use daily wear lenses, which means that you wear them by day and dispose of them by night.

Regular disposable contact lenses should be replaced every two weeks.

And there are some special lenses that are made of silicone, so you replace them monthly and you don't need to take them out at night.

So you see, it all depends on what type of contact lenses you use. Ultimately, you should look at the contact lense container to find out when to replace them.
