Hi Koby,

 

Since you are inquiring for high school students, I'm guessing your students will be wearing these for no more than 1hr at a time. So, the "low end" eye wear will be comfortable enough for an hour. As I looked for links to include, I noticed many places are out of stock. Probably a side effect of the pandemic. So, you may have to resort to buying in bulk and rolling the cost into the students' technology/book fees.

 

For physics, you can likely get away with safety glasses. I recently got my first pair of prescription glasses. So, I linked my old and my new styles below. I've worn these for 8hr shifts and most of the time I forget I even have them on.

For goggles, I'll defer back to my undergrad years. The goggle style linked below was comfortable enough to wear for 4hrs at a time. The tendency to fog is related to the venting type (ventless, direct, indirect). You'll need to take a close look at the experiments planned and decide what venting type you'll require. Some brands, like the one linked here, do offer anti-fog lenses. https://www.fullsource.com/radians-gg011uid/

 

If most of your students tend to take all three science courses during their time in high school, you could have them purchase a pair of safety goggles rated for both splash and impact.
