Transitions® Photochromic Lenses.
Transitions® lenses brought to you by TOG, in partnership with Transitions® Optical Ltd. [1]
What optical stores need today?
Your patients want comfort and clarity all day.
Your team wants choices they can explain without a script.
You want a supplier that keeps promises across Europe.
Transitions® Photochromic Lenses fit daily life. Indoors, they are designed for clear vision. Outdoors, they darken to help manage bright light, then return inside. Staff can explain that in one breath, which keeps the consultation natural.
Clearer than ever indoors 2 | Darkens in seconds | Responsive to light
Stores also ask for tidy ordering and simple training they can share with new team members. TOG Europe supports retailers, independent opticians, labs and distributors with a practical setup and plain documents.
A few things that help:
- Simple range that is easy to present
- Tracked delivery across Europe
- Contact TOG when you need quick help
Teams often get better acceptance when they describe everyday moments, like walking from the clinic to the car, rather than quoting jargon. Your dispenser can pair frames, materials and coatings to suit the prescription and the wearer’s routine. And to showcase exactly how it would look, utilise the Transitions ® Colour match Tool in store. This tool is downloadable from the TOG Eye Pro Hub.
Transitions® GEN S™ lenses are the fastest darkening lenses in the clear to dark photochromic category. Indoors, they remain completely clear, but outdoors, they darken within seconds². These lenses are exceptionally light-sensitive, reaching category three darkness levels in just 25 seconds³ and lightening back to clear in under two minutes⁴. Additionally, they boast enhanced durability and performance over time⁵.
Transitions® GEN S™, the new lens standard: A giant leap of technology, available now.
It is the photochromatic molecules in the lenses that adapt to light. With Transitions® brand technology, the superiority of this product lies in its patented, exclusive formulas. Each formula is integrated into the surface of the lens, where the molecules smoothly and constantly recalibrate to ensure the optimal level of light reaches the spectacle wearer's eyes, whether under cloud cover, in bright sunlight, or indoors.

Why Transitions® belongs in your store (B2C)?
Patients want convenience. A Transitions® lens adapts as they move through their day. Fewer swaps. Less squinting at the door. It is a simple idea that helps your team close the loop after the refraction.
In dispensing, keep the chat about lifestyle. Start with how much time they spend outside, how sensitive they are too bright light, and whether glare is the main complaint.
Match the family and finish with frame and coating choices. It keeps the value clear. We can also provide you with the Transitions® Colour Match Kit for you to support your patients in choosing the right colour transition lens for their style and frame.
Many stores like the lens family structure of TOG. And many clients love the “Good Better Best “options. You can build clean bundles for your market without overcomplicating things.
