Eyeglasses made with high index of refraction materials are thinner than those made with standard index materials. This is because the higher refractive index allows for better light bending, which means less material is needed to achieve the same optical prescription.
Mid-index lenses are thinner and lighter than standard lenses, perfect for moderate prescriptions. High-index lenses are even thinner and lighter, designed for stronger prescriptions. If you're shopping for lenses, Eyeglasses Direct and Glasses direct are nice options.
Materials through which light cannot pass are called opaque materials. Examples include wood, metals, and thick plastics.
Thick lenses have more curvature and can focus light at different points, while thin lenses have less curvature and focus light at a single point. Thick lenses are used in cameras and microscopes for magnification, while thin lenses are used in eyeglasses for vision correction.
Materials such as metal, concrete, and thick walls block radio waves most effectively.
Opaque materials do not transmit light. These materials block the passage of light and do not allow it to pass through them, resulting in no transmission of light. Examples include metals, wood, and thick plastics.

A standard flashcard is typically around 0.2 to 0.3 millimeters thick, which is similar to the thickness of a typical index card.
A jigsaw can typically cut through materials up to 2 inches thick, depending on the type of material and the blade being used.

Mice cannot chew through materials like metal, glass, or thick plastic.
The recommended length for a long pilot drill bit when drilling through thick materials is typically 6 to 12 inches.
