Comfortable, versatile and polarized!
I bought these glasses with the 1.5 magnification. I frequently fish from a boat or kayak with a spinning rod, and on foot with a fly rod. In my mid-40's, my eyes aren't as strong as they used to be. The bifocal magnification on these works well with clarity for tying fishing knots, particularly with mono or fluorocarbon line. They fit very well, are comfortable to wear, and the rubber pieces help hold the glasses in place. I chose brown tint lenses specifically for fishing. The bifocals so far are pretty easy to get used to, but aren't distracting when staring straight ahead. I have high hopes for these, and the fact the included case has bright orange accents makes the case easier to find with my fishing gear, or just in case they fall overboard. For the money, I'm very pleased. I'll certainly update the review if that opinion changes, but don't anticipate it being the case. I have numerous KastKing spinning and casting reels, along with some clothing, and am extremely pleased with the value, construction, and durability. They keep making quality products that don't break the bank.

Great Sunglasses
Just received the Estero Sunglasses and they are awesome! The Optical Clarity is excellent. I primarily use them for fishing. No more switching from Sunglasses to reading glasses to tie knots. The polarized lenses with the mirrored lenses cut the glare and I am able to see things in the water that are invisible to the naked eye, or non-polarized shades.The lens coating resists water spots and keeps them cleaner, even with water spraying while underway in the boat. These are well built and seem like they will last a long time. The description says soft touch nose pads but they did not have any nose padding, just the hard plastic frame material, as is clear in the pictures. Nonetheless, they Stay Put on my face and fit well.The wraparound shape cuts side glare. Exceptional quality, unbelievable at the price.

100% Perfection
I bought these for my husband who LOVES them! He says the fit is comfortable in every measurement. The clarity if the lenses are magnificent. The color of the lenses are soothing to the eyes while making the world look vibrant without glare and the perfect amount of darkening. I love the way they look on his face! Very handsome! He wears them daily while driving. They seem very durable & substantial.

I can see my graphs!
Love the fit, they stay on but not to tight . Love the readers in them, actually better than my costas. Only thing I’m not crazy about is the lens color but with the price, I’ve ordered another pair! Hope I like the color.

Great value
I bought these primarily for their bifocal and polarization options. When fishing in my boat, these glasses stay on even at 55 miles an hour turning my head sideways. They didn’t fog in hot, heavy humidity conditions. I’m very happy with my purchase and would highly recommend these glasses.
