Contact lens have more options

 The most usual is the contact lens be soft, the name in Brazil is gelatinosa, jam kind, had the hard ones that aren't common to see to sale, ptobably one hard is to be for each person, because doesn't acomodate if is a little diferent.

The most common is the one soft for one year, but also have, the ones that have to be replace for each 2 months, the ones that are replace for each month, and one that is daily.

The daily one the advantage! is you don't need clean it, in the end of the day you put in the trash... in Brazil you buy like 50 pair of package, and they came all salled and you receive in the same day, they are individually package and until you doesn't open it is clean, so also can have days that you don't use lens you don't gonna lose one pair.

The ones that are to be changed at 2 months or monthly, is that you can be less care and damage your lens because you are harsh, you still have to be clean, so no soft lens in your hand endure one year, have the ones that can be changed monthly, and the care remain the same for the yearly ones, is the safe of your eyes.

Have the factor price, but I think that isn't very important you can find yearly soft ones that are more expensive, the factor that would not make me advise the one day ones is that are so for careless people that the temptation is use the lens for more hours that you would use if you use one that are yearly or monthly, when you have one lens that endure more you some times take the lens out of the eyes, during the day, this is good for your eyes, also the eyedrop help to inject oxigen in your eyes, so isn't so normal you wake up put the lens in the eye hold 16 hours take out the lens only in the time to sleep, what receive less oxigen usually grow older faster... isn't to be worry? Have people that assecure that the daily your eyes gonna breathe very good, if is true that is very good, in my city who have high-grade glasses use to be cruel with their own eyes, like I hate me I make pain on me... nobody need be cruel to doesn't born perfect, in my mind need glasses is a visible born imperfection that happens to everybody why be so critics, is like the imperfection that we can fix.
