What's the right age for children to wear contact lens?

The above answers are absolutely right and I will echo it again, it is about the child understanding that they will have to take up that responsibility to ensure their hygiene is up to standard and that they are able to effectively manage and care for the lenses. We see children as young as 6 who are able to proficiently manage lenses although we always want the parents to be involved in some way to ensure they are doing things the right way. This can be followed through until they have proven to be responsible to manage it on their own.
