I was unfamiliar with Designer Optics, but am glad I took the leap of faith and ordered from them. The Ray Bans I purchased are legit, and they were shipped promptly and without any issues.
Good quality and comfy. Easy to purchase, as an added bobus they were on sale!
I love my ray-ban unisex polarized shade. Not too dark during the day and perfect for night driving for the high beam headlights. Light weight and feel good on my face.
These are very nice sunglasses but Inam returning for two reasons. Main reason being the lense has a couple different Ray Ban logos etched in the lense which is visible from the outside. The RB initials are on the left mid way down the lenses which appears like a scratch on the lenses when looking through them. At first I thought it was an actual flaw until I saw the RB and realized it's some sort of additional marking. Secondly the frames are too large for my face so will have to submit a return. The return process seems effortless so thankful for that. Best to buy local where you can actually try them on.
Great daily sunnies for office work. Its dressy and feels light.
Looks great. Loved the virtual try on app as I purchased these online
Great for cutting out the glare from the sun especially while driving, looks stylish (unisex), fits well and most importantly, it's comfortable. Definitely recommend!
