Compare photochromic glasses by frame size and lens shape

Shopping for photochromic glasses in Morocco? These three Belvoir&Co models have light-adaptive lenses listed as UV400 in their product specifications. Their shapes and measurements differ, so compare more than just lens colour.

• Diamond Cut Willow Transition Blue | Gold — rimless Diamond Cut silhouette; 134 / 18 / 53 / 38 / 140 mm.
• Mabel Transition Black | Stealth — rectangular rimless silhouette; 141 / 18 / 55 / 34 / 140 mm.
• Kennedy Transition Blue | Gold — a wider listed front; 143 / 18 / 60 / 43 / 140 mm.

Measurements are frame width / bridge / lens width / lens height / temple length. The Kennedy example has a 9 mm wider listed front than Diamond Cut Willow; that alone does not determine how either pair will fit. Check product photos, listed specifications, availability and the photochromic versus sunglasses guide before ordering. Lens darkening varies with conditions; do not assume these work like permanently tinted sunglasses.

Frequently asked questions

What are photochromic glasses?

Photochromic lenses change their tint when exposed to certain light conditions. The degree and speed of tint change vary by lens. Learn more in our transition lenses vs sunglasses guide.

Are transition lenses the same as sunglasses?

No. The term describes lenses that adjust their tint, while sunglasses are generally made for sunwear. Check each model's specifications for its intended use.
