I have to take off my glasses when sparring, which has a negative effect on visibility, measuring distance, land punches and kicks where they are supposed to etc.. I bought this shield to be able to have the glasses on so that I can spar better. Though I can see how the face shield would be good for someone who only wants to protect their face, if you want to BOTH protect the face AND have glasses on, look for another solution. The headgear with the face shield attached is very uncomfortable to put on and off. In order for the face shield not to apply to pressure on the rims or frame of your glasses when putting it on, you might need to leave the side straps unfastened, and when you do that, it is rather difficult to fasten the straps once the whole set is on your head. Again, if you're planning to buy this for greater face protection and the chance to have your glasses on, I don't recommend the shield. I for one will sell my shield (which I was able to use two times anyways) and buy either a ski goggle or a clear plastic shooting goggle with a strap to tighten it around the head.
