For sun and poor visibility: Instead of carrying multiple pairs of glasses in your prescription, now just pull your sunglasses or night vision goggles over them.
Ideal for spectacle wearers: These glasses fit easily over your normal visual aid. Inexpensive, flexible and ideal for driving, for example!
Protection and sharp vision: The sunglasses protect your eyes from blinding sunlight. The night vision goggles give you a full view in the dark: Thanks to contrast enhancement you see everything much sharper. Also ideal in fog, driving snow and heavy rain.
Polarized lenses on both sunglasses and night vision goggles reduce glare and filter out reflections.
