WebBecause these distant objects are being focused in front of the retina instead of onto it, the objects appear blurry. To correct the problem, the lens must be weakened. To weaken the lens, a diverging or negative artificial lens is used, that is, a concave lens. A diverging lens is wider at the edges than at the middle. the terminal list detachment

WebWe would like to show you a description here but the site won’t allow us. WebThe question states that the eye is farsighted. We can see that the light rays enter the farsighted eye and these rays cross paths at a point behind the back of the eye. Finally, the question shows a convex lens, lens A, and concave lens, lens B, and asks whether placing lens A in front of the eye would make the light entering the eye focus ... WebPlacing concave lenses in front of a nearsighted eye reduces the refraction of light and lengthens the focal length so that the image is formed on the retina. Convex lenses are … service now omv
