Transitions ® Lenses
One pair for every light, every moment.
The Superpower of Transitions® Glasses
Transitions® glasses come with advanced photochromic lenses that give you the freedom to carry a single pair of glasses for all your needs.
How do Transitions® Light-adaptive Lenses Work?
Transitions lenses come with a special chemical coating that gives it the capability to change the tint of the lens depending on the lighting conditions. They remain completely clear indoors but become dark like sunglasses as soon as they are exposed to ultraviolet light (UV light) from the sun.
It makes them a perfect option for someone who wants a single pair of glasses that they carry throughout their day. Transitions ® offers different models in their lineup for different needs and you can pick the right pair depending on your vision and lifestyle needs.

FAQs
My eyesight is fine, do I still need Transitions® glasses?
Even if you have perfect vision, Transitions® lenses offer valuable protection. They help filter harmful blue-violet light indoors and protect your eyes from UVA/UVB rays outdoors. Plus, they enhance your style, seamlessly adapting to different lighting conditions for both function and fashion.
Do Transitions® have UV protection coating?
Yes, all Transitions® lenses have a UV protection coating that blocks 100% UVA and UVB rays.
How much do Transitions® lenses cost?
It depends on which Transitions® lenses you choose. However, Specscart offers the best prices on Transitions® lenses and you can add Transitions® GEN S lenses to your glasses for £100 £70 only.
Can I choose Transitions® lenses with all Specscart glasses?
Yes, all the frames can be customised with Transitions® lenses at Specscart. They’re suitable for all vision types - non-prescriptive, single-vision, and varifocals.
What is the difference between Transitions® sunglasses and Transitions® glasses?
Transitions® sunglasses and glasses are the same things. It’s the Transitions® lenses that change a frame from clear glasses into sunglasses after reacting to UV light. People use these two terms to refer to glasses with Transitions® lenses.
Do Transitions® lenses turn dark while driving?
Transitions® GEN S and other photochromic lenses need UV light to react and car windshields are capable of blocking UV light. As a result, they don’t react inside cars. However, Transitions® XTRActive New Generation lenses can react to visible lights as well so they can turn dark while driving as well.
What is the difference between reaction and Transitions® lenses?
Photochromic/reaction lenses are the type of lenses that change colour from dark to light and vice-versa. Transitions® is a branded patented product of these photochromic lenses. Transitions® Opticals was the first company to manufacture photochromic lenses and obtain patents for their fastest light-adaptive formula.
How do I care for these lenses?
You can clean Transitions® just like other lenses – with a lens spray and microfibre cloth. All Specscart frames come with a free cleaning kit which you can use to clean your lenses.
Are Transitions® lenses worth it?
Transitions® lenses are completely worth it for most people as they offer you the freedom to carry a single pair of glasses for different lighting conditions. They seamlessly adapt to changing light conditions. Additionally, you get protection against blue-violet light indoors and harmful UVA/UVB rays outdoors.
What are photochromic lenses?
Photo means light and chrome means colour. Photochromic lenses change shade when exposed to light. They turn dark like sunglasses when exposed to sunlight and fade back to clear when indoors.
