I mixed up the toric from non toric contact lens. now how do I tell which is which? is one thinner than the other?
There should be a manufacturer name on it somewhere. Then around the front element of the lens you will get a series of numbers and symbols. That tells you the technical spec of the lens.
no you ken not have lends on cp and tell me how do you send money at your friends thx
Easy way: Use it to form an image of the sun or moon, and measure the distance of the image behind the lens. When the object is at infinity, the distance between the lens and the image is the focal length of the lens.
You can typically tell which objective lens is in the viewing position by looking at the number or color marked on the lens. The objectives are usually labeled with magnification values (such as 4x, 10x, 40x, etc.) or distinct colors to help identify them while using a microscope.
It will tell you on the camera lens or on the box. ask a salesman or look on the internet.
dont know plz you tell me the answer in detail
Photo meaning light.Tele meaning sound. Lens isn't a root word I'm just going to tell you that.
Accommodation is the depth cue that uses the tension of the muscle attached to the lens to gauge how close an object is when it is less than four feet away. This cue involves the eye adjusting its lens to focus on nearby objects.
To find the magnification of a lens, you can use the formula: Magnification image height / object height. This formula compares the size of the image produced by the lens to the size of the original object. The magnification value will tell you how much larger or smaller the image appears compared to the object.
It is lens. The lens consists of the lens capsule, the lens epithelium, and the lens fibres.
)( is a concave lens() is a convex lens
The ocular is the upper lens and objective is the lower lens
