Key Features
Design: A rimless, lightweight construction with a gold-toned bridge and hinges.
Lenses: Gradient-tinted lenses (fading from a dark smoke/grey at the top to a lighter brownish-pink at the bottom), which are excellent for driving or reading outdoors.
Branding: The "Dior" logo is subtly etched into the top corner of the right lens, and there is a decorative gold emblem on the temples (arms).
Style: This minimalist yet bold look is typical of Dior's eyewear collections from recent years, such as the DiorColorQuake or similar contemporary lines.
Tips for Care & Identification
If you are looking for more specific information or want to verify their authenticity, here are a few things to look for:
Check the Inside Arm: There should be a model name or number (e.g., "Dior[Name] S" or a string of numbers and letters) followed by the frame and lens measurements.
"Made in" Stamp: Most authentic Dior eyewear is manufactured by Safilo Group in Italy. You should see "Made in Italy" stamped on the inside of one of the temples.
Lens Quality: High-quality lenses like these should provide full UV protection. If you plan on wearing them frequently in the sun, it’s worth ensuring they are rated for UV400.
