Advantages

 

Specially designed for the near vision

One of the most important goals when developing a PAL design is to provide it with a good near vision zone. IOT accomplishes this with precision; the Alpha H20 has been developed to provide wearers with a high quality lens with an excellent reading area.

The near region has been extended to allow wearers to provide a superb near vision range . Astigmatism around near field has been also reduced to improve feelings of comfort when using near vision. This combination of features produces a final lens with high definition in near with an optimized and clear far vision.
