I use some smith and Wesson shooting glasses I bought to use at a rifle range Where safety glasses are compulsory.
I had previously used cheap workwear glasses but found they suffered from distortion.
On occasions where I have not bothered with them in the past I have had nothing more sinister than insects fly in eyes but that said it always seems to happen at the most awkward of times which have meant descending with one eye closed.
Generally I find once on I soon forget I am wearing them.
