Optical Hard Coating Solution
HCG (Hello Coatings & inks Guru) Optical Hard Coating Solution is formulated for optical surfaces, such as the faces of a lens. The coating does not interfere with how the lenses function and does not affect vision, but creates a permanent bond with the lens that reduces the appearance of hairline scratches which is common to lenses.
