New supplies and chemistry involved in the most recent generations on the lenses have produced significant development in addressing the two basic requirements for selection :

Older generations (and some present generations) keep a yellow or slightly jaundiced hue even if not exposed to extremely violet mild (indoors for example). The most recent technology Transitions are broadly regarded to become the very best obtainable and practically completely distinct inside the absence of extremely violet.

Most newer photochromatic lenses create a rapid changeover from gentle to dark as they are exposed to extremely violet - the actual test and the differentiation would be the rate at which they regress in the darkest tint to obvious. Again Transitions lenses are extensively regarded as best at school in this regard. 

Transitions lenses really are a broadly held trademark to get a certain (latest) generation of materials and technologies that are combined and sold beneath the "Transitions" model. Other (but related) names usually are not the identical, and therefore are usually regarded to become not as good, as they may be from more mature generation photochromatic technologies.

Ultimately - do not anticipate your photochromatic lenses (irrespective of which model or technologies) to make considerably of a difference whilst driving, as the windscreen of the auto is made to absorb most of the UV ahead of it enters the cabin - hence the lenses within your eyeglasses have absolutely nothing to respond with. In case you require or would really like tinted lenses even though driving, you happen to be much better off obtaining two pairs from the very same body with prescription very clear and prescription tinted lenses.
