Fits my eye sockets better than the higher priced models that had more of an oval shape for the eye socket that did not seal right

The hinges are very stiff and I hope they don't break with repeated folding.  The large fit is perfect over my modern glasses that were 5-1/4" outside the hinges  and 1-1/4' top to bottom of the lenses.  The picture is accurate from the side, but it doesn't show the slight curve of the bottom towards the side.  Maybe that is why a reviewer thought they looked feminine since the bottom was not straight across.  the lenses seem to have a tiny bit of distortion that I didn't notice in the Polar Optics from Wal-Mart that I lost (and the hinges were looser).  However, these LensCovers are cheaper and will work on those very windy days when the Slip-ons I have are in danger of flying off.  The darkness is just right.

I tried these goggles after I kept getting headaches from the usual type of swim goggles that fit closer in the eye socket.  These are very comfortable (for goggles, anyway) and don't leak.  I also don't get the deep indents in my face that I get from other goggles.

I really like these compared to the other ones i have bought. I have very dry eyes they fit good and keep my eye from drying out. I where them all the time, great price for what you get

Got the grey lens version for a trip to Africa (Okavango Delta and Hwange National Park). I wear contacts and dust is a real problem for me. Turns out that the Okavango didn't need them since it is mostly green and not much dust. Hwange was a different story. Mostly dry and lots of dust when the driver is rushing around in the open vehicles. It did sit flat on my face without any gaps which was the main reason I got them and no dust bothered me. The fit was a bit tight for me and I had to close my eyes when I put them on otherwise my eyes were constantly being pulled open. Probably needs to be a bit wider vertically for me, another half inch would be perfect. The reason I got the clear version was because at dusk and on night drives the grey lens were just too dark. So when we got home I ordered the clear lens version. Still have this minor issue with the tight fit so I give it four stars. The fit issue is minor though. It does seal entirely to my face. Other goggles I have all have an open gap somewhere and dust will sometimes float in. These never had an issue and did not fog up at all.

These are significantly higher quality than Ray Ban Aviators. These 61mm fit my modest sized face perfectly. I recommend you go to the Randolph Engineering website to look at the simple size chart to determine what size is right for you. The AGX lens are well rounded and high quality, much more versatile than the amber lenses in my honest opinion. My complaint however is toward Amazon who sold them to me, they were supposed to include the Randolph Engineering maintenance kit as even the contents paper in the box states. However, to my unfortunate luck, Amazon did not include it and the box was slightly torn. The price however was unbeatable compared to other sellers so it is negligible to me. I will be emailing Randolph engineering to see if they will send me a maintenance kit with my proof of purchase and if they don't I will have to pay $9 to order the kit which I think it necessary to have just in case.

These glasses fit my head well compared to another similarly prices pair that I bought (Torege Polarized Sports Sunglasses For Man Women Cycling Running Fishing Golf TR90 Unbreakable Frame TR011). They also seem to be sturdier than the other glasses.

I haven't tried the expensive version of these glasses but I cannot argue against these glasses. As soon as I put them on you can tell things look a little clearer. My eyes don't feel as strained and I have 0 headaches. Even though they don't cover the sides of your eyes doesn't both me. I just avoid letting light in that way lol

I was having serious eye fatigue due to working on a computer 8 hours a day and spending leisure time on the computer as well.  I wanted the much more expensive Gunnar Vinyls, but I thought I would try this much cheaper alternative first.  These glasses work.  They all but eliminate my eye strain.  They are an exceptional value at approximately $15.  I like them so much that I will probably buy the $90 Gunnars just to see how higher end computer Glasses perform.  It would be nice if these glasses had slight magnification like the Gunnars, or crystal lenses.  Then again, it would be nice if Gunnars didn't cost $90.  I am totally satisfied with this product.  I saw where other reviewers stated that they seemed cheap.  They don't seem like the most expensive pair of glasses, but for $15 the quality is just fine.

Before these sunglasses I owned a pair of Oakley's M-frame Strike. I paid 200+ and after trying the ESS I think Oakleys are way overpriced. The ESS built is solid, fit better in my big head and the lens is distortion free and as good as the Oakley's. The frame itself in my opinion feels and looks more solid than the Oakley M-frame. On top of that they throw in a nice case that costs $10-15. Add to that a 5 year warranty from ESS and the choice to buy a replacement lens, at a decent price, for 50% off if you scratch or destroy your ESS lenses. I guess is a no brainer. Good bye Oakleys.

UPDATE 8/20/2014
After 16 months of using the sunglasses almost every weekday for about 30-40 min. The frame looks like the first day, well built. The lens has very minor scratches which show that they have some level of scratch resistance.
THE BAD: The inside coating of the lenses has wore off at the lower edge about 2-3 mm. However this does not impair the field of vision so I will continue to use them.

Took a chance to see if these were any good versus ordering a custom pair through the dive shop.  This is a decent mask for scuba and I love the bifocals.  Now I can read my gauges again.  Some reviews mentioned you have to close one eye or you see double, I had that problem but my wife did not (got her a mask as well) so probably different based on how they fit on your face.  Still, even with one eye close, I am happy to see my gauges and dive computer again.

Using other reviewer's advice, I ordered a pair of these rated a half step higher than my prescription strength in order to offset my astigmatism. When the goggles arrived, I put them on and had a look around my backyard (because, you know, wandering around with these in your front yard would be wierd!) and was pretty happy with the vision improvement. I've worn them in a pool since then. They seem slightly under strength (kind of like an older prescription: it still works, but you know it could be better) but these are still good enough to dramatically improve my underwater vision at a bargain price. Now I can see pool walls and other swimmers before bouncing off of anything or anyone. No leaking at all - my eyes stay dry the whole time I'm swimming. I like the metallic mirror lenses too. I'm looking forward to my next snorkeling trip. Thanks Splaqua!

Lenscrafters did not have any high end red eyeglasses. I had a pair in the past and liked the pop of color.  Finally after getting boring brown ray bands, I looked on amazon and found these.  Ordered them and took them into Lenscrafters where they put the lenses into them for me.  If you like Ray Bands, and other more expensive frames because they fit so well,then you will like these!

I had LASIK surgery 3 months ago and was given a pair of sunglasses by the doctors that did the surgery.  But after getting this pair, those are getting tossed.

These are far sturdier and also have that wrap-around look like Schwarzenegger in "The Terminator" to keep the sun out, but are made out metal.

I also like the hinges which allow for greater durability as well (one of the pictures I am attaching)

I purchased them for fishing, so I haven't thoroughly tested them yet. However, upon trying them on, I was quite pleased that the reading lenses don't get in the way of regular view. I had another brand and style that were too distracting to wear while driving. These are a definite upgrade.
Update: Been wearing these for weeks now. I like them better than my Maui Jims. Ordered 2 more pair.

I purchased this last year and am about to purchase again.  These lenses are slightly thinner than the Oakley lenses they replace and have a slightly higher radius curve. So what that means to us the user is after they are fit into frame they are snug but cause the frame to fit a bit loose.  For me this was a benefit. They are prone to getting scratched and that's why it's 4 instead of 5 stars. Great bargain when compared to the licenced lenses.

First off this fits the Asian face. I'm 6'3 at a "healthy" 240lb and these fit my face just fine and feels comfortable on my nose. The price in my opinion was a great deal for the model I bought. Clarity is excellent and it works great as I drive a lot. Out at the park or when I'm taking a break between paintball games, it does a great job of cutting out glare, no squinting and you can still see colors just fine.
