Ray-Ban Silver / Emerald Photochromic (RB3768 003/M1)

Ray-Ban RB3768: A silhouette that stands out

Some sunglasses you wear because you have to, and some you wear because they make a difference. The Ray-Ban RB3768 are the kind you notice the moment you put them on: the Silver frame sits naturally, the Emerald lenses sharpen everything you see, and suddenly the world comes into clearer focus. We have been fitting people in Alpedrete for over 20 years, and this model still stops people in front of the mirror.

Designed by Ray-Ban, who have been getting sunglasses right since 1937. And yes, you can tell.

What you feel when you wear them

The thin-profile metal frame is light enough that after a few hours you forget you are wearing them. The adjustable nosepads adapt to your nose without leaving marks or slipping, even on hot days.

Photochromic: a lens that thinks for you. Ray-Ban photochromic lenses contain photosensitive molecules that react to UV light by changing their structure — and with it, the lens tint. Indoors or in low light, the lens clears to about 80% light transmission, letting light through naturally. Outdoors, when exposed to UV radiation, it darkens progressively, reaching full protection in under 30 seconds.

Behaviour varies with temperature: on a cold mountain day the lenses darken more; on a very hot day the tint stays slightly lighter. Note that they do not activate inside a car because the windshield blocks UV rays — but once you step out, the transition is immediate. Ideal for people who spend their day moving between indoors and outdoors, combining both environments without having to switch glasses.

Measurements: lens width 56 mm, bridge 17 mm, temple 145 mm. A classic fit that works for most face shapes.

Frequently Asked Questions

1. Does this model include a hard case?
Yes, Ray-Ban RB3768 come in their official rigid case with the brand logo, accompanied by a microfiber cleaning cloth and original documentation certifying authenticity and warranty.

2. Can I get prescription lenses fitted?
This model can accommodate prescription lenses in many of its finishes. As a thin-profile metal frame, it is possible to install prescription lenses. Contact us on WhatsApp with your prescription and we will confirm feasibility with no obligation.

3. How should I clean and maintain my Ray-Ban sunglasses?
Wash them periodically with lukewarm water and mild hand soap. Always dry them with the included microfiber cloth. Do not use paper towels, alcohol or chemical products, as these can damage anti-reflective coatings and lens protection. Always store them in their hard case when not in use.

4. What is the difference between the versions of this model?
The Ray-Ban RB3768 vary by frame color (Arista Gold, Black or Silver) and lens type: standard (Dark Green, Dark Brown, Dark Blue), mirrored (Mirror Red, Mirror Green), polarized (Dark Grey Polarized) or photochromic (Emerald, Amethyst). Polarized lenses eliminate glare, ideal for driving; photochromic lenses automatically adapt to changing light conditions.
