Abstract

The optical lens provided by this invention includes a lens barrel and a plurality of lenses. These lenses are sequentially arranged within the lens barrel from an object side to an image side along an optical axis. Each lens has an object-side surface facing the object side and allowing light to pass through, and an image-side surface facing the image side and allowing light to pass through. The lenses include at least one visible light-absorbing lens. The optical lens further satisfies at least two conditions to provide good optical quality while saving cost and reducing size.
