  • Stylish and Practical! Not too tight on the face.
Color: Black/Grey Gradient Lens Width: 54 Millimeters
I recently bought the Ray-Ban Women's RB4378 Square Sunglasses, and I am so glad I did! I have a square-shaped face, and finding sunglasses that complement my facial structure can sometimes be a challenge. But these fit my face perfectly – they have just the right shape to soften the angles of my face while still giving off a sleek, stylish look. The square frame is modern but classic enough to go with any outfit, whether I’m dressed casually or more put-together. What really stands out to me is how practical these sunglasses are, especially for driving. I drive a lot, and I often find myself driving during sunrise or sunset when the sun is at that difficult angle and it’s hard to see the road. These Ray-Bans do an amazing job of blocking the glare while still giving me clear vision. The lenses are just dark enough to protect my eyes but not so dark that I struggle to see things around me. Whether it’s sunny or overcast, these shades are perfect for keeping my eyes comfortable and focused on the road. Another great feature is that they cover the eye area well, providing full protection from the sun. The lenses are wide enough to shield not just the eyes but also the delicate skin around them, which is a huge plus when you’re outside for long periods. No squinting, no eye strain – just clear, comfortable vision. The frame itself is lightweight, so even if I wear them for hours at a time, they don’t feel heavy or uncomfortable on my face. In terms of style, they’re an absolute winner. The design is chic without being over-the-top, and I’ve gotten so many compliments on how stylish they look. They have that signature Ray-Ban quality and elegance that instantly elevates any look. Whether I’m running errands, driving, or spending the day outdoors, these sunglasses are my new go-to. Overall, I couldn’t be happier with the Ray-Ban RB4378 Square Sunglasses. They fit well, look great, and are incredibly functional, especially when it comes to driving in bright sunlight. If you have a square face like mine or just want a stylish, protective pair of sunglasses, I highly recommend them! ... show more

  • High quality shades
Color: Havana/Gradient Brown Lens Width: 54 Millimeters
I got these for Christmas, and didn’t know how often I’d wear them because I have so many other pairs. But when I tell you these work well, I seriously mean it! I felt like I could look into the sun they protected my eyes so well. I took an international trip where I felt I may lose them or damage them so I wore a cheap pair I wouldn’t mind losing instead, and whew they were shit. I was squinting so bad, and all I could think was how much I wanted to be wearing these instead. So do it! Splurge! Definitely worth the price tag!! ... show more

  • FAKE Rayban sunglasses
Color: Black/Grey Gradient Lens Width: 54 Millimeters
These are fake, DO NOT BUY them! They are flimsy and nothing like the original ones. You can tell right away when you feel the glasses how cheap they are made.

  • Cute
Color: Havana/Gradient Brown Lens Width: 54 Millimeters
These are super cute, love the look of them, and not a bad price for a name brand. I’ve been wearing them for about a month and the screws have become so loose already. Not a huge deal and an easy fix obviously but I’ve had other pairs of sunglasses for years wearing them daily and never having this happen. Makes me wonder how they’ll hold up long term but other than that they’re great. ... show more

  • Not made in Switzerland
Color: Opal Blue/Dark Grey Lens Width: 54 Millimeters
These glasses are just like the ones from the gas station. Too expensive for what they are. Website says made in Switzerland but say made in China right on the product. Not worth the money.
