Ray-Ban Wayfarer - Black - Crystal Green - 2140F

Yes, the Ray-Ban Original Wayfarer Classic with green lenses (MPN: `RB2140 901/58`) features genuine polarized lenses, designed to reduce glare and improve visual clarity, as indicated by the 'Polarized' marking and the superior glare reduction.

Authentic Ray-Ban Wayfarers often have 'Ray-Ban' engraved on the right lens and 'RB' etched into the left lens near the hinge. Check for the iconic Ray-Ban logo on the temple and ensure the case and packaging are of high quality. Purchasing from authorized retailers is the best way to ensure authenticity.

The Ray-Ban Original Wayfarer Classic frames are generally compatible with prescription lenses. It's best to consult with your optician or an authorized Ray-Ban dealer to discuss fitting prescription lenses into this specific frame model (`RB2140 901/58`).

The '50-22' refers to the dimensions of the sunglasses. '50' indicates the width of one lens in millimeters, and '22' indicates the width of the bridge (the part that rests on your nose) in millimeters. These measurements help determine the overall fit.

Polarized lenses are excellent for most outdoor activities, significantly reducing glare. However, for certain specific activities like skiing (where you need to see glare off ice patches) or pilots (who need to read LCD instruments), non-polarized lenses might be preferred. For everyday use and driving, they are highly beneficial.

Always store your Ray-Ban sunglasses in their original protective case when you're not wearing them. This prevents scratches, dust accumulation, and potential damage from being crushed or bent.

Rinse lenses with lukewarm water and a drop of mild dish soap, then dry with a clean microfiber cloth. Ensure the cloth itself is clean.

Visit a reputable optical store for professional frame adjustments. Minor adjustments to the temple arms or nose pads can significantly improve fit.

Unfortunately, lens scratches are typically permanent. Prevention is key: always store glasses in their case and clean with proper materials. For severe scratches impacting vision, lens replacement may be an option, check with an authorized dealer.

Polarized lenses are designed to block horizontal glare. They can sometimes interact with LCD screens (e.g., car dashboards, phone screens, ATMs) making them appear dark or showing rainbow patterns. This is a normal characteristic of polarized lenses and not a defect. Try tilting your head to observe the screen.
