What is the highest magnifying power of contacts?

Question

How bad of vision can they correct?

Answer 1

Contacts don't magnify.  They correct refractive error.

Frequent replacement (disposable) soft lenses are available from +8.00 to -15.00.

Standard non disposable soft lenses are available from +20.00 to -20.00.  Rigid lenses and custom soft lenses are available in any power.

20/xx notation does not specify contact lens power.  It specifies how well a particular eye sees either with or without glasses or contacts.

Answer 2

Up to a + or - 20.00 in soft lenses, and up to 30.00 in RGP lenses ( rigid)

EDIT****

You want to know in the 20/20 form?...can't be done. The 20/20 measurement is the visual acuity you have, it is really nothing to do with the power of the lenses, or the prescription you need.

Answer 3

Contact lenses can correct most any vision.  They do not magnify, however.

Answer 4

contact lenses are not magnifying glasses  and for vision,   the contacts   lens are for vision correction   - only,   there should not be any confusion about it

Answer 5

I can't put it into 20/100 form, sorry! But my doctor said they sometimes go up to -12.00. My mom is a -9.75 which is really bad already (everything is blurry for her, even close up) so you can imagine how far they go.
