Claim 0:
1. A computer screen filter, comprising:
an optical layer, for changing an optical characteristic of a light emitted from a computer screen, and the optical layer being substantially in a rectangular shape and having two sides; and
a bonding mechanism layer, locally disposed on three edges of the optical layer,
wherein the bonding mechanism layer is disposed on a side of the optical layer, and the computer screen filter is only coupled to a side of the computer screen by the bonding mechanism layer in a non-permanent fixation manner,
wherein the bonding mechanism layer is substantially L-shaped and disposed at only two corners of a side of the optical layer separately, and the optical layer is capable of reducing a divergence angle of the passing light, the bonding mechanism layer is non-continuously disposed on at least one side of the optical layer, and the optical layer partially absorbs a visible light with a wavelength of 400-500 nm emitted by the screen.
