What are the lenses made of? - The lenses are made of high quality optical glass, custom designed and cut to provide crystal clear viewing.
Do they come with a case? - No! They ARE their own case. Just press the release button and they unfold. When you’re done using them, press down and they retract into their own housing. Like a turtle!
Can I hang them around my neck? - Yes. There is a hole that lets you attach them to a clip or lanyard.
How do I focus them? - There is a small dial in the middle, between the two lenses. Just turn that dial until your vision becomes clear.
How big are they? - They are just 164 x 53 x 68 mm, about the same size as a cellphone.
