Foggles are glasses that are used as a tool during the pilot training process. The glasses are designed to limit the pilot's field of vision. This assists the learning process by encouraging the pilot to fly with only the help of the flight instruments. In instances when flying at night or in inclement weather, the pilot needs to be able to land with no visual aids external to the craft. Foggles are pilot training glasses that meet all Instrument Flight Rule (IFR) certification requirements.
The polycarbonate lenses are frosted to partially block the wearers field of vision. The open area is just large enough to allow the pilot in training to have a full view of the instrument panel. Foggles are light, comfortable, and easy to wear because they are designed like regular glasses.
Excellent value product...way better than sharing the community property flight school foggles. One word of caution...DO NOT wear any foggles to a bar on a dare you may not like what you wake up with!
The lower, clear portion of the lenses had fog overspray. I was able to remove it with light solvent, but needed to be very careful.
My Foggles arrived yesterday and I was disappointed. Apparently they are made from Encon 1400 safety glasses. Whoever sprays the barrier spray on them needs to improve their masking, or train the person doing the job. There was over spray all over what was supposed to be the clear area andit was difficult to focus on the instruments. After rubbing rather hard with an iCloth Aviation cleaning wipe a lot of the over spray came off but not all of it and, as expected, there are small scratches on the clear part.

Per supplier: It's hard to be definitive with this answer since it depends on the profile of the prescription glasses. If they are low profile, it should not be a problem, however they were not designed for use with prescription glasses.
