My dream pair

I am absolutely obsessed with these glasses!! I had the brown ones for like 3 years and have bought other lenses to try different styles but I missed how chunky glasses looked on me so I purchased these and I could not be any happier. Idk why I didn’t buy them earlier. Eyebuydirect is literally the best company for glasses ever nothing at beats the quality, style, and fast shipping. I can’t wait to rock these for another two years or so haha. I hope Eyebuydirect keeps making chunky glasses like these. I really love when they come in transparent pastel colors especially and I hope more come out!! Number 1 loyal customer here.

Great frames! Kind of heavy

I love these frames but they often slide off my face and give me a headache. I wear my glasses 24/7 so if you do too I wouldn’t get these. More for a here and there wear. Super cute glasses and they match my style perfectly!
