Not perfect, but these are great goggles and will get the job done.

I have tried the Uvex S345C, cheap $2 goggles, Safety Goggles Vented Clear Shop Chemistry Glasses , and a few other goggles from my school's student store and loaner pairs. This UVEX S345C is the clear winner. For reference, I have lab sessions that last 3 hours and 50 minutes in a lab that seems to be around the 70-75 F mark. I am 6'2" that wears a hat size 7.5 (New Era 59/50), and glasses with 53-17-145 measurements.
I also do not lower stars based on personal factors (ex. due to my own face shape, preferences, etc.)

These goggles do a great job. Their vents work fine to keep fogging at a minimum, create a good seal, and are cool looking.

My favorite thing about these that beats out a majority of other goggles, is its cloth like elastic band. Almost all the other goggle companies use a rubberized band, which may hurt and pull at hairs when worn. The cloth band slides on and off very easily and will not be pulling out any hair.

Unfortunately, it is not as easy to adjust the band. You will need to play around with it to understand its nature.

Another complaint is that when worn over glasses (my experience), the bottom section of the goggles are completely unsealed and will lead to exposure of vapors to your naked eye. Without glasses, however, it fits just fine and are quite unique in the looks department compared to the average green shaded goggles.

If you have any questions just let me know. I get notified by email.

These are working well for me. They're not as good looking as I had hoped but they're not hideous. They are comfortable. They work almost exactly how I want them to. They're not full on exactly perfect and I look much better in my Oakley's so I am getting a pair of prescription Oakley's but the price difference between these $12 glasses that do the trick and the $240 frame + $400 progressive lenses is extreme. My insurance is paying for most of it so hurray me and hurray that I will have these for whitewater rafting trips or other things that could strip me of my much more expensive option. The bottom line is that after $12 and some getting used to then they work well, fit well and look fair. They're not Oakley's but if you don't have great insurance good luck AND insurance only pays once so you'll want these to wear in the mosh pit unless you're filthy rich in which case just buy everything and stop reading reviews ;)

Great goggles, love that they are tinted, they seal water out good but do for up which is annoying

Polarization on lenses do great job cutting blur.

Foam breathing area around frame is a little small, causing fogging if you work up a sweat.

So-so quality for the price.

Fit well though not as comfortable around the eyes as some other goggles I've tried. They keep the water out though, and that's what's most important!

The fit is nice, and the quality of the Goggles is good. Also, good a combination of lenses is included.

Great price and nice goggles.  The anti- fog is damn good and they seal well.  The nose piece squishes my nose a little but whatever- As long as they're functional, no big deal.  Overall they are comfortable and I am happy.
Plus they came with this nice plastic case, fancy schmancy indeed.

They work as expected. I wanted some goggles to go over my glasses while I solder. They do fog up a bit, but for the price they are good.

The goggles have a good field of vision and keep the eyes warm. However the foam tends to break away and leave little particles. Sometimes they get in my eye.

Speedo Vanquishers are the go to brand for competitive swim goggles. They definitely get the job done.

Pros: They are comfortable, and don't leave circles around your eyes. Much more comfortable than Swedish goggles.
They keep the water from coming in.
They are definitely stylish (or as stylish as swim goggles can be).
They come in a variety of colors.

Cons: The straps they come with are not easy to adjust. You have to pull the bands really hard in order to tighten them. Definitely not as easy to adjust as those goggles with a bungee cord.
They work really well until they fog up. As soon as you see them fog up the first time, forget it.

These are very nice goggles for the price. They have a foam that makes it fit and feel nice while wearing them, but foam also is glued over the breathing vents which traps moisture in the mask and causes them to fog or sweat somewhat easily. Overall they are a good buy, I just ripped off the foam over the vents and it helps them breath. Good product for the price.

These are a great pair of goggles that can be used for many things like airsoft or any other activity that requires you to have eye protection. They have thick plastic lenses that are shatterproof, flexible lenses and frame. The strap is durable, would take a fair amount of pressure to snap. There is one drawback. They fog up if not ventilated correctly, you probably do not want to use these for cycling. They have vents but the vents do not work very well.

They are somewhat leaky unlessI really push them on my face. But it does solve the puffy eye issue with the smaller goggles

They fit over my glasses perfectly and it's made quite well. The only problem is that there's not much cushioning around the edges where your face meets the outline of the goggle so it does get uncomfortable to wear for long hours.

Oh yea they fog up big time if your working up a sweat.

They are alright. Somewhat fog-free. Good contrast.

They're comfortable and easy to adjust but the optics aren't great. They're clear but they distort distances more so than most goggles. I swim competitively and it took a while to get used to judging distance from the wall for flip turns.

Nice goggles and good quality material. I took them on vacation and used them at the beach and the pool.  They did hold up very well. As soon as we got back to the hotel I made sure to rinse them off with cool water and let them air dry.  But I did notice that after a few uses the lenses started to fog up.  I have been very careful with them and kept them in their cases when not in use so it wouldn't get scratched. Overall they're pretty decent for the price.
