Hard-coating by dip is the guarantee for premium scratch resistance applied to a lens. Machine, cleaning and hard-coating application adapted to the anti-reflection process are paramount for the market success. With the cleaning and hard-coating line CHC 20 , Allentown Optical Corp. provides a superior tool and a full solution integrated into our lab.
UV and AR
Below is a comparison of Allentown Optical’s NEW AR COATINGS Vs. off the shelf AR. The graph shows the UV reflection off the backside of the lens. Notice how Allentown Optical’s AR levels off at 400nm, while normal AR increases rapidly and reflects back into the wearer’s eyes.
|Ultraviolet A||UVA||400 – 315 nm|
|Ultraviolet B||UVB||315 – 280 nm|

Retinal Bliss DES
The Digital Eye Strain solution that addresses BOTH sides of the issue
Why Retinal Bliss DES?
Unfortunately, many of the coatings and glasses that are being presented as solutions only address one side of the problem. Allentown Optical Corp. now presents the solution that addresses both the front and the back side of the issue. The Digital Eye Strain Solution Allentown Optical Corp. presents Retinal Bliss – DES as the first solution that addresses the factors that influence Digital Eye Strain on the front of the lens as well as the back. The front of the lens includes a specially formulated HEV Attenuator which helps to reduce the intensity of light associated with LED technologies while addressing environmental light issues as well. The back side of the lens includes Allentown Optical Corp.’s Retinal Bliss – HEV, the only Anti-Reflective coating that address the harmful and irritating effects of reflected HEV (High Energy Visible) light. A Digital Eye Strain solution that is only on the front of the lens, only provides half of the solution.
