Combat Goggles Glasses

Does the military have goggles that are eye glasses at the same time?
Does the military have goggles that are glasses at the same time or do you wear regular military issued glasses when in combat i must imagine thats a disadvantage they can fall off and the sweat or fog on the glasses can really cost you your life.
i know that goggles also get sweaty and foggy is there a soloution for this?
There are a number of options for prescription eyewear in combat. There are regular eyeglasses; "BCG"s; and inserts for your ballistic eyewear, gas mask, and goggles. You are normally allowed to only wear what is issued to you.
You don't need to wear goggles all the time unless mandated by your command or you are performing a task that requires them. Anti-fog coating will help and there are goggles approved by the military that have little fans built in to provide ventilation. If they fogging is that bad you can just take them off and wipe them down.
