Lab goggle recommendations?
I don't have specific product recommendations (and I think they're discouraged in general on SE), but these are the general principles:

You'll only get condensation on goggles (or anything else) if they're cooler than the dewpoint of the air contacting them. If your goggles are cold, you'll get condensation.

If you're sweaty, it'll be worse.

If the goggles are glass or another high-thermal-mass material, they'll stay cold longer, making the problem worse.

If the goggles are ventilated, humid air can escape from the space between your goggles and your face, making the problem better.

Does the problem only arise after you've been working in the lab for a while, or does it happen as soon as you put the goggles on? If the latter, you might be able to fix it by just putting the goggles in a warm interior pocket for a few minutes before you start work.

There are also spray-on anti-fog products for goggles. If you can't find one of those, try rinsing the goggle interior surfaces with soapy water, then not rinsing the soap off. The soapy film left on the goggles won't prevent condensation, but it will slow the formation of droplets, which will slow the fogging effect.
