I use these when I scalp my dead, previous season north GA bermuda grass in late Winter and Spring. It's an awful, multi-day project. You just have to keep that dust out of your lungs and eyes if you have even a little bit of allergies. These are better than regular sunglasses and keep the particles out. They still fog a lot though especially if you are wearing a mask (I wear a 3M valved N95 for this task). If it's hot and you are sweating, they will fog up. I think I will solve this next time with some no-fog wipes. That should do the trick....but decent protection either way. They come with an eleastic strap which is great since regular glasses arms interfere with my worktunes earmuffs to play my music. I look like a total dork but I don't care. I've cobbled together a complete allergy barrier.The style looks kinda biker ish but it gets job done.These are very comfortable using either the arms or the elastic strap. I have a clear & wide field of view. The foam cushion around the lens should help lessen any impact. The elastic strap is easy to adjust and is holding up well (elastic will degrade over time.) Two points to consider:- The description (when I purchased it) said "anti-fog". They're not anti-fog. Not even close. In moderate humidity and/or high temps, they will fog up over time.- They do not fit properly when I wear my RZ Mask. They probably won't fit when wearing respirators. They may fit when wearing cloth dust masks (I tend to not use those.) Your mileage may vary.Love these goggles but they aren't fog proof. Pretty scratch resistant but they glaze over pretty quickly in cold weatherHe had gotten a piece of wire in his eye and was wearing those cheap ones that they give u at work, we ordered these while setting at the eye Dr waiting to be seen. He loves them so much they fit like a TI use it for high pollen season to protect my eyes from terrible allergy, And I found it can be use for the whole year because confutable and dark. Good to buyUPDATE::without me even asking, and to my happy surprise, ergodyne took it upon themselves and sent me another pair. they happen to be the color i had originally wanted, so bonus. i did have to come back here and put in writing that i have been wearing the replacement pair for a few weeks now, and these do not have the issue i was having with the first pair. the anti-fog lenses are wonderful, and a welcome change from the hazy, obstructed view that most glasses of any sort give when they fog up. and being in a time where face coverings are required, which exasperates the issue, i can wear my mask properly, and comfortably while still using my eye protection without ant complications.i like the foam gasket that is included, but i haven't yet switched the ear pieces out for the goggle strap. nice that it's an option though.so, the first pair i had must have had a defect, and the company recognized that, and had enough confidence in their product to make it right. i don't find that kind of backing of goods very often.i've had these for about a week, and the anti-fog coating is already not holding up on the right side lens. this was a big part of the reason I chose to purchase these safety glasses. with having to wear a face covering while at work, it makes doing my job nearly impossible, and dangerous to be looking through foggy lenses. i got rid of the last 2 pair of safety glasses I had for that reason. after reading the description for these, and how it boasted that the anti-fog was indelible , made to last for the life of the glasses, which can handle taking a direct blast of buckshot apparently... i thought i found what i needed. i guess not. i can see fine out the one side, and a blury mess on the other. and after the first pair i ordered, which the seller didn't inform me until nearly a week after they were to have arrived that they were on back order, I ordered a second pair because I needed eye protection that would allow me to still have clear vision. well, looks like my hunt will continue on until I finally find the safety glasses that truly won't fog up on me, and last more than a week or so. i don't have money to just keep throwing away on false claims.The glasses are very nice and comfortable to wear. U bought these to help when I'm running an open cab dozer in the dust and to help with the bright sun. I love the adjustable band that came with it. It really helps keep dust out and the glasses on your face no matter what your doing. The only reason I gave it a 3 on durability is bc it says they are scratch resistant but my pair came out of the package with a scratch on the inside of the right lense right at the corner of your eye. So when I wear them I see a line in my right eye all the time. I am going to contact seller and see of they will send me a replacement and then I might change my review. Definitely would buy another pair!No hacen justicia a la descripción del producto. Al usarlos con cobre bocas se empañan inmediatamente. Sin cubre bocas tardan más pero igual se empañan hasta el grado de no ver absolutamente nada. Cabe señalar que en mi trabajo hace calor, sudamos, hay niebla constantemente ya que es un aeropuerto. Y no soportó ni la más mínima condición a las que me encuentro. En general. Muy malos. Me arrepentí al primer día de uso.They are good looking work goggles. I love them!Los mejores lentes de seguridad ! Y el polarizado está increíbleSon livianos pero esto no le resta calidad y comodidad.
