Are eyeglasses made with high index of refraction materials thin or thick?
Wiki User
∙ 7y ago
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.

What is the difference between mid index and high index lens?
High index lenses are thinner and lighter than mid index lenses, making them a better choice for stronger prescriptions. They also reduce the "bug-eye" distortion that can occur with thick lenses. However, high index lenses can be more expensive than mid index lenses.
What Materials through light can not pass are called?
Materials through which light cannot pass are called opaque materials. Examples include wood, metals, and thick plastics.
What term for materials that do not transmit light?
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.
What are the materials that block gamma rays?
Materials that can effectively block gamma rays include lead, concrete, steel, and thick layers of dense materials such as barium or tungsten. These materials are able to absorb and scatter the gamma rays, reducing their penetration and protecting against radiation exposure.
What can't gamma rays pass through?
Gamma rays can pass through most materials, but they may be absorbed by dense materials such as lead, thick concrete, or thick layers of water or soil. Additionally, high-energy gamma rays may interact with atoms in the material and create secondary radiation.

How thick is a flashcard?
A standard flashcard is typically around 0.2 to 0.3 millimeters thick, which is similar to the thickness of a typical index card.

What are some good quality materials for a toy sword?
There are many good quality materials for a toy sword. Examples of good quality materials for a toy sword include the materials of plastic and thick foam.
What is the thickness of a standard counter top?
The standard counter top is about 1.5" thick. However, materials like tile can increase the thickness. Your counter can also be thicker, depending on the materials you use. For instance, concrete counter tops can be as much as 3" thick. Soapstone and other surfaces typically range from 2-3" thick.
What is 016 thick?
016 thick typically refers to a material that is 0.016 inches thick. This measurement is commonly used in manufacturing, construction, and various other industries to specify the thickness of materials such as metal, plastic, or paper.
What term for materials that do not transmit light?
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.
What is the volume of a 3 by 5 pack of index cards?
It will depend on the number of cards. If the package is 1 inch thick, the volume would be 15 cubic inches.
