YONGIN, KOREA — A contact lens manufacturer, Neo Vision ( stated that “we have developed a new ‘Internal Absorption Technology’ which interfuses pigment inside the lens”.
Recently, as the use of color lens increases, the interest in safe contact lens is also increasing. Especially in case of some low price lens which prints out pigment directly on the outer surface, it is known that the pigment directly touching cornea may cause pigmentation making the safety in using color lens come to the fore.

Neo Vision has released products applied with N.S, Nano Sandwich Technology which coats the lens after coloring on the lens surface. Patented and registered of the trademark as original technology by Neo Vision, it features safe use of lens without side effects such as coloring or bleaching of cornea by coating the outer surface of the lens once more.
This time, they developed new IA, Internal Absorption Technology upgraded from Sandwich Process after three years of research. Permeating and absorbing U.S. FDA approved safe pigment into contact lens material; the color pigment is not directly touched with cornea.
Not only minimizing the eye fatigue as the pigment is not touching the eye, but it also maintains the percentage of water content in the material as well as gas-permeability. As the pigment is penetrated through lens material, the lens gets thin giving only a little sense of difference.
Such an Internal Absorption Technology is applied to recently released color lens, ‘Shiny-DALI’, and this product features thin slice, 42% of water content, and excellent comfort as it prevents sore eyes and inflamed eyes.
A person from Neo Vision said that “we expect to make various products for safer and more convenient use by applying newly developed Internal Absorption Technology” and added “we will work on R&D activities continuously for customers’ eye health”.
In the meantime, Neo Vision was established in 1993 under the name of Poong Gwang Optical Research Laboratory and incorporated in 2003; Neo Vision provides dioptric lens and cleaning solution as well as color lens and other products to 50 countries of the world. Last June, they started building Osong Factory equipped with full automation facility following Icheon Factory and Wonju Factory planning to advance into mass production in earnest.
