Discover our cutting-edge digital lens technologies: BSP, CEV, and ATL. Each is uniquely engineered to enhance clarity, comfort, and personalized vision.
BSP Technology (Back Surface Progressive)
The BSP is our entry-level digital technology. Progressive lenses made with this technology have the progressive surface on the back side of the lens, and a simple curve, typically a sphere, on the front side. The progressive surface is calculated using a pure geometrical method that produces lenses with similar optical performance as conventional progressive lenses, but with the advantages of the digital process, like flexible designs, variable corridor lengths and insets.
CEV Technology (Custom Engineered Vision)
CEV is the most advanced technology available to make digital lenses. The important difference appears when calculating the back surface of the lens. Instead of using a pure geometrical method, CEV technology is based on an advanced three-dimensional calculation model that takes into account the actual position of the lens and the natural movements of the human eye. The result of this innovative calculation method is a progressive lens that is personalized and provides better vision in all zones of the lens.
ATL Technology (Add To Life)
This methodology, is a technological breakthrough in digital lenses. It provides a strict control of average power in the far distance vision zone and virtually eliminates peripheral spherical power error. Its image stability reduces swim effect and provides more comfortable vision. The ATL is a technology specifically designed to improve comfort when viewing electronic devices such as smartphones, tablets, and computers.
The Lens Theory delivers advanced, custom-crafted lenses for every vision need—from screens to everyday life.
