How dark do photochromic lenses get?

You can see this technique if you compare a new transitions lens compared to an old one. What you see may be the different tint times and the intensity of the tint varies slightly.
Photochromic or “adaptive” lenses darken when subjected to UV light, such as when you walk outdoors. When you are no longer exposed to the effects of UV, (i.e. walk indoors), the lenses return to their clear state. Transitions lenses are photochromic lenses that block 100% of harmful UVA and UVB rays. Besides protecting your eyes from glare outdoors, photochromic lenses offer yet another important benefit — they help protect your eyes from harmful blue light.

All photochromic lenses are appropriate for Anti Reflective treatments.
With a UV-blocking windshield, bright light coming through your windshield will not cause your lenses to darken, leaving you squinting and straining.

Transitions®XTRActive®lenses do activate moderately when behind the wheel as they are made to also react to visible light, and several people choose them for driving. Furthermore, Transitions®Drivewear®sun lenses are another choice made to self-adjust to changes in visible light. And they are polarized to improve visual performance and the driving experience by automatically changing their degree of darkness and color.

Besides changing in different light conditions, these lenses change their clarity consistently in different climates and temperatures. Hoya Vision produces Sensity lenses in a variety of colors, designs, materials, and coatings for anti-reflection. They are not as clear indoors as other photochromic lenses, but they provide extra comfort in bright sunlight and when driving. Photochromic lenses typically will not darken inside a vehicle as the windshield glass blocks most UV rays. Recent advancements in technology allow some photochromic lenses to activate with both UV and visible light, providing some darkening behind the windshield. In other words, prescription safety glasses, safety glasses, sunglasses, eyeglasses and much more.
SunSensors are constructed with mid- and high-index plastic materials and are available in gray and brown tints in a number of lens designs. Transitions Gen 8 — Transitions Gen 8 lenses, introduced in the United States in July 2019, are the fastest light-adaptive Transitions lenses available.
These dyes contain molecules that undergo a chemical reaction every time they touch UV rays. They are typically useful for outdoor sunglasses instead of as general-purpose lenses. With the photochromic material dispersed in the glass substrate, the degree of darkening depends upon the thickness of glass, which poses problems with variable-thickness lenses in prescription glasses. With plastic lenses, the material is normally embedded into the surface layer of the plastic in a uniform thickness of up to 150 µm. While both colors of transition

In transition lenses, photochromic compounds have been included in these lenses, and it is the Ultra violet rays from the sun that trigger these compounds to transition or darken. When out of sunlight, these lenses changes back again to a clear-state through what’s known as a type of thermal process.
