Focal length for concave lens
WebConvex lens - along with sign convention v = +ve, f = +ve, u = -ve 1/f = 1/v + 1/u 1/f = 1/v + 1/-u 1/f = 1/v - 1/u We apply sign convention to make the equation obtained by similarity of triangles to make it general as the signs for f and v are opposite with respect to concave mirror and convex lens the difference arises WebIf you have myopia or nearsightedness, you would use diverging lenses(concave) to shift the focus of your eye lens backwards so that it can focus on the retina.
