What is the maximum power for contact lenses?

[Marthaville]

I want to get some contacts but I really have a high prescription.Does anyone know What is the maximum power for contact lenses?

[Martic]

This differs from each optical stores, but I've heard that some online stores cannot do contact lenses with prescription greater than -7.00. As your prescription is greater than that power, you may go to your eye doctor.

That may depend on the brand of your contact lenses. The maximum power for some type of contact lenses can reach -10.00, while some can be up to -12.00.
