What are two basic kinds of lenses?
Two basic kinds of lenses are converging lenses, which focus light rays to a point, and diverging lenses, which spread out light rays. Converging lenses are thick in the center and thin at the edges, while diverging lenses are thin in the center and thick at the edges.
Is a lenses in glasses concave or convex?
Lenses can be concave or convex depending on their shape. Concave lenses curve inward and are thinner in the center, causing light to diverge. Convex lenses curve outward and are thicker in the center, causing light to converge. Glasses can have either concave or convex lenses, depending on what vision correction is needed.
What are some examples on diverging lenses?
Some examples of diverging lenses include biconcave lenses, planoconcave lenses, and concavo-convex lenses. These lenses are thinner at the center than at the edges, causing light rays passing through them to diverge. Diverging lenses are commonly used in combination with converging lenses to correct vision problems.
How are concave convex and biofocle lenses alike?
Concave, convex, and bifocal lenses are all types of optical lenses that are used to correct vision problems. Concave lenses are thinner in the center and thicker at the edges, diverging light rays. Convex lenses are thicker in the center and thinner at the edges, converging light rays. Bifocal lenses have two different optical powers, typically one for distance vision and one for near vision, allowing individuals with presbyopia to see clearly at different distances.
How are convex and concave lenses different from each other?
Convex lenses are thicker in the middle than at the edges. They cause light rays to converge. Concave lenses are thicker at the edges than they are in the middle. They cause light rays to spread out, or diverge.
What cranial nerve focuses lenses of the eyes?
optic
What is a sentence using optic in it?

What is a product that has germanium in it?
Wide-angle camera lenses, fibre optic cables, and integrated circuits all contain Germanium.

Where can one purchase a case for contact lenses?
One can purchase a case for their contact lenses at many online stores. If the user does not want to shop online, they can find these cases at their local optic store. Amazon, however, has many contact cases in their inventory.

What is the cost for a month supply of Optix contact lenses?
A months supply of Optic contact lenses will typically cost the user between 20 and 50 dollars depending on the type of contacts one needs. If one has vision insurance, this may cover some of the costs?

Where can I buy contact lenses cheap online?
If you want to find good discounted contact lenses, basically any contact lens you're looking for try http://www.1800contacts.com/. You can find a variety of different contact lenses there, for a cheaper price. Also, if you go to a vision center, that vision center might have an online website, which sells contacts much cheaper than in the actual center.
