The main contribution of corrective lenses is to improve vision by correcting refractive errors such as nearsightedness, farsightedness, and astigmatism. By adjusting the way light enters the eye, corrective lenses help focus images onto the retina, resulting in clearer vision.

What are examples of a converging lens?
Examples of converging lenses include the lens in a magnifying glass, a camera lens, and corrective lenses for nearsightedness. These lenses are thicker in the middle and cause incoming light rays to converge to a focal point.
Also called a diverging lens?
A concave lens is also known as a diverging lens because it causes light rays to spread out or diverge when passing through it. This type of lens is thinner at the center than at the edges and is commonly used in corrective eyewear for conditions like myopia (nearsightedness).
What is the parts of the hand lens?
The main parts of a hand lens include the lens itself, the frame or housing that holds the lens, the handle for holding and maneuvering the lens, and sometimes a protective cover or case.
How power and focal length related?
Power in optics is inversely proportional to the focal length of a lens. A lens with a shorter focal length will have greater optical power, while a lens with a longer focal length will have less optical power. This relationship is important in determining the strength and magnification of corrective lenses used in eyeglasses and contact lenses.
Why do objects appear closer that it really is when viewed through a convex lens?
A convex lens converges light rays towards a point known as the focal point, causing the image to appear magnified. As a result, objects viewed through a convex lens may seem closer than they actually are due to the way the lens refracts light. This magnification effect is utilized in magnifying glasses and corrective lenses to aid in vision.
How do people adapt to limited vision?
by wearing glasses or contact lens. Even corrective eye surgery can help.
What are examples of a converging lens?
Examples of converging lenses include the lens in a magnifying glass, a camera lens, and corrective lenses for nearsightedness. These lenses are thicker in the middle and cause incoming light rays to converge to a focal point.
What contribution of the Lydians still exists today?
The Lydian's main contribution is that they invented the first coin.
Who cannot receive LASIK surgery?
patients with higher degrees of refractive error will still need some type of corrective lens.
Also called a diverging lens?
A concave lens is also known as a diverging lens because it causes light rays to spread out or diverge when passing through it. This type of lens is thinner at the center than at the edges and is commonly used in corrective eyewear for conditions like myopia (nearsightedness).
Main contribution of research in development?

Can power of a lens be negative?
Yes, the power of a lens can be negative. A negative lens, often referred to as a concave lens, diverges light rays that pass through it. This type of lens has a focal length that is also negative, indicating that it forms virtual images on the same side as the object. Negative power is typically associated with corrective lenses for myopia (nearsightedness).
What structure of the eye continue to grow throughout a lifetime?
A perons ears and nose grows through out their entire life.
What was the main contribution of the Hebrews?

Is Lasik the only corrective eye surgery available?
"Lasik is not the only corrective eye surgery available, but it is one of the most common. Other procedures exist for treating cataracts. Some people are candidates for having lens replacement surgeries which do not use lasers at all."
What type of eye does not need a corrective lens to focus the image?
An eye with normal vision does not need a corrective lens to focus the image properly. The cornea, lens, and other components of the eye work together to refract light onto the retina, creating a clear image without any blurriness.
