The opacity of the lens is called a cataract. It causes clouding of the eye's natural lens, leading to blurry vision, sensitivity to light, and difficulty seeing at night. Cataracts can be treated with surgery to remove the cloudy lens and replace it with an artificial one.
Opacity can be accurately measured using a device called a nephelometer, which measures the amount of light scattered by particles in a substance. This measurement provides a quantitative value for the opacity of the substance.
The preserving fluid in the lab may cause the protein structure of the lens to denature, altering its shape and affecting its clarity. Denaturation can lead to cloudiness or opacity in the lens, reducing its ability to refract light properly for clear vision.
A lens that is thicker in the middle than at the edges is called a convex lens. It is a converging lens that causes light rays to converge at a focal point.
A concave lens is called a negative lens because it causes light rays passing through it to diverge, or spread out. This is in contrast to a convex lens, which converges light rays and is called a positive lens. The negative or positive designation refers to the effect the lens has on the light rays.
This is called opacity. Materials that are opaque do not allow light to pass through them.
a catract is any opacity within a lens the opacity can be very small (incipient cataract
The treatment for opacity of the crystalline lens, also known as cataracts, is typically surgical removal of the cloudy lens and replacement with a clear artificial lens. This procedure is called cataract surgery and is a common and highly successful surgery that can improve vision significantly. Glasses or contact lenses may be needed after surgery to optimize vision.

The upper lens is called the ocular lens or the eyepiece.

The basic code would be to set the opacity low then make use of ':hover', in CSS this is:.trans { opacity: 0.8; }.trans:hover { opacity : 1; }You can use test in your HTML code to test if it works.The following code is designed to work across all browsers:.trans{filter: alpha(opacity=80);-khtml-opacity:0.8;-moz-opacity:0.8;opacity:0.8;}.trans:hover{filter: alpha(opacity=100);-khtml-opacity:1;-moz-opacity:1;opacity:1;}
when a beam of light is passed through the convex lens it converges the beam of ligth.hence convex lens is called a converging lens.
