Why Transitions® Gen S™ matters in day-to-day wear?
Light changes all day.
People move between buildings, from shade to full sun. They expect the lens to keep up.
How to frame the opportunity with Transitions® Gen S™?
With Transitions® Gen S™, we intend to reframe prescription eyewear and transform the lens industry with ground-breaking technology to offer an elevated vision experience to consumers. The objective is to gain penetration using 4 key steps and upgrade clear lens wearers to dynamic lenses. We want to attract younger wearers to make them discover and adopt Transitions® products.

- Step two: Bring more awareness to Transitions® by leveraging our new campaign and all the tools available
- Step three: Provide a clear and impactful message on the benefits of Transitions® Gen S™ by developing more on our pillars. GEN Speed, GEN Style, GEN Smart.

If you sell to practices, ask yourself
Do your customers want the newest name, or do they want fewer complaints after dispensing?
Most of the time, in our experience, it is the second one.
88% wearers agreed that Transitions® GEN S™ lenses adapted so fast to light that they didn’t or barely noticed the changes⁵
Whether you’re an optical retailer, or a manufacturer, integrating Transitions® Gen S™ lenses into your product offering, positions your business at the forefront of eyewear innovation.

Confirm these before production

A TOG-specific operational point you can use that our TOG supply chain can support.

- Full frame handling
- Picking, packing, and shipping
That is the kind of detail that our labs and RX partners want, because it affects your daily workload.
Choosing a manufacturing and supply partner in Europe
Labs usually judge you on two things.
- Consistency
- Delivery reliability
TOG Europe is:-
- A partner of Transitions® Optical Limited
- A manufacturer and supplier of ophthalmic lenses across Europe
- A supplier of finished and semi-finished lenses for optical labs and distributors
- A provider of full RX services for retailers and independent opticians
Distribution detail that matters for lead times
TOG Europe delivers lenses to our local warehouse in Poland for faster replenishment.
If you run a multi-store rollout, ask yourself
Do you have one ordering method for every store, or does each store do its own thing?
That one decision changes your remake rate.
Ordering supextensionport and TOG Eye Pro Hub

TOG promotes TOG Eye Pro Hub as a portal to support ordering and fulfilment, and TOG Europe allows businesses to register interest via the enquiry form.
TOG also states this clearly

- It only works with optical businesses and cannot process one-off prescription orders for individuals
