Abstract
An optical lens includes a lens body and an anti-reflection film. The lens body includes an optically effective portion and a peripheral portion surrounding the optically effective portion. The optically effective portion is configured for transmitting light therethrough. The optically effective portion has a first surface and an opposite second surface. The first and second surfaces each have a curvature of greater than zero. The anti-reflection film is formed on the first surface of the optically effective portion. A reflectivity of the anti-reflection film to light rays has wavelengths in a range from about 400 nm to about 850 nm being lower than 2%.
