Great Sunglasses at a great price!
I live in a perpetually sunny place where we are always walking the beach, in the ocean, biking, etc and and you don't really want to wear your $300 Maui Jim's for fear they will get stolen, lost, or broken. These had such good ratings, I thought I would try a pair for my everyday beach sunglasses. I have a thin face and struggle to find glasses that fit without big gaps on the side, and having them sitting down on my cheeks. These fit amazingly well! They are super light and comfortable, give great eye protection and coverage, and look as good as my old Bolle's, which started to delaminate on the lense after sitting in the hot car for decades. I wound up ordering another pair with different frames because I couldn't beat the price. These are easy to see through, not too dark, and give good glare reduction because of the blue reflective lense. I've never tried this type of lense but it is recommended for bright sun. As a bonus, these came in a nice cloth pouch inside of a protective case! Don't hesitate to buy these sunglasses! They are a great value.

Comfy & looks nice
I don't buy expensive sunglasses because I am pretty rough on them or I lose them. However, I do appreciate good quality. So, this is my second pair of Kast King glasses. I inadvertently scratched my first pair after a couple of years of heavy wear. I appreciate that these glasses are comfy and look good on. I also like the fact that they come with a nice case & microfiber pouch to keep them in good order for travel or while in my beach bag. In addition to beach & pool, I also wear these while driving, boating, playing golf, and pickleball. Great value!

Comfort & value
They're lightweight, not to tight, but stay in place. The copper tint is perfect for me. I have a more expensive pair in this color & really like them. I purchased these as an inexpensive alternative for times when they might be at risk of damage or loss. They're polarized, so the glare is suppressed. The tint is perfect for cloudy days, it brightens things nicely.

Great replacement for Oakley Cohort’s
HIGHLY RECOMMEND as an alternative to expensive glasses. The lenses are not quite as crisp as a pair of $200 Oakley’s, however they are pretty dang close! I was very impressed with how crisp and clear it is to look through them. The biggest difference with expensive lenses is there a little more difficult to clean. They smear easily so don’t use your T-shirt. To avoid damaging the coating or scratching the lens definitely use a lens cloth The brown and chartreuse lenses are great for the bright Arizona sun. I’m not squinting and I can see through the dusty haze. They are also not too dark for slightly cloudy days. I have will be ordering a second pair with a lens for lower light conditions.

Great if you wear contact lenses
If you wear contact lenses - these sunglasses are a must. I was struggling with blurred vision while driving with other sunglasses. They are very light weight and my vision is very crisp when using them. Love the tortoise shell color and quality of the frames.

Perfect with concerns
The size, style and color are just what I was looking for. These sunglasses are made well and are comfortable to wear. I bought the black with smoke lenses and the color and gradation of the lenses is perfect. I don't see anywhere on the item or the packaging that they are 100% uva/uvb which is the main reason I am buying sunglasses. I bought these (and others) for sun protection against AMD. The design covers my eyes in the best way with the moderate wrap around style along with the size of the lens that is perfect. My only concern is the warning on the box that states "the product can expose you to chemicals including lead and phthalates" etc. etc. I will be calling the company directly regarding this warning. Other than that, these glasses are perfect for me and I wouldn't hesitate to buy another pair.

Good value, just really wide. Catches hair often.
Wore them on my vacation. Good enough to wear, affordable enough to lose and it not be the end of the world. But they were wide on my face. Guess I can play around and adjust them somehow. UPDATE. Wearing them at a higher frequency now and already my hair has gotten stuck in the arms, the part over the ears where there's rubber and plastic. The gap catches my hair and doesn't easily let go. Don't get this if your glasses usually go near your hair.

Greta sun protection and very comfortable to wear
Externally, the look of these is very nice and the earpieces have a nice fit that is comfortable and stays on your ears. Wearing them does add a bit of an enhancement to the color of things outside and it does great to protect against the sun. I have noticed that during sunset hours, they do make things appear a bit darker than normal, which makes it feel later outside. Love these. 5 Stars
