Do transitions lenses change to different shades if each lens is a different prescription?

Question

I have an unusual prescription for glasses. One eye needs a much stronger prescription than the other. I am considering transitions lenses for my new glasses, but read somewhere that if each lens is different they change color at a different rate and therefore would never match. Is this true? Does anyone have any experience with this?

Answer 1

I have been fitting/selling these for more than 8 years now, and this has never been an issue for my patients. The only time that we have mis-match problems is when someone wants to replace just one lens - then the old lens and the new lens do not match because the Transitions feature wears out very slowly

Answer 2

No. This used to be true to an extent for older glass photochormic lenses, but the transitions colour is is a thin film incorporated in the surface of the lens, so the bulk of the lens matters little.

An old lens, however, will react somewhat differently to a new one, so if one lens is damaged of an existing pair, it can be a good idea to change both lenses. (cost vs benefit!)

Answer 3

No that is not true. No one could run around with their lenses different colors in the sun or shade, or while driving. They turn according to the light and darkness not by the prescription of each eye.

Answer 4

No that is not true. Hubby and I have had them in the past and each of us have a different script in each eye and this never happened to us.
