Pin Hole Eye Glasses for Vision Improvement
Different colors and models available.
Suitable for age group 5-22 years.
Pinhole glasses make for a clearer image for those with vision defects.
Pinhole glasses are typically eyeglasses with lenses that are full of a grid of tiny holes.
They help your eyes focus by shielding your vision from indirect rays of light.
By letting less light into your eye, some people can see more clearly.
Pinhole glasses are also called stenopeic glasses.
