There are various different types of contact lenses available which are defined by their differing characteristics:
By lens material: either soft or gas permeable (also called RGPs)
By wear schedule: i.e., whether they are taken out before sleep. Lenses can be approved for either daily wear or extended (overnight) wear.
Replacement schedule: for instance, how often they must be disposed of and replaced with a fresh pair. Disposable lenses are most popular option and are replaced every two weeks or monthly. Daily disposables are discarded each day which makes them a safe and easy option for teens.
By correction modality: Whether they are spherical, toric, astigmatic, or bifocal.
What if contact lenses just don't work out?
It’s a good idea to let your teen wear contact lenses for a trial period, so they can prove that they are ready for the responsibility. If they don’t work out, your teen can go back to wearing glasses and re-try contact lenses later on.Part-time wear of contact lenses is also an option and daily disposables are particularly good for this.
