1.74 Semi Finished Lens Blanks for Ultra Thin Glasses
What Semi Finished Lens Blanks Can do?
Spectacle lenses production units that transform semi-finished lenses into finished lenses according the precise characteristics of a prescription.
The customization work of laboratories enables us to provide a wide variation of optical combinations for wearer needs, especially as regards the correction of presbyopia. Laboratories are responsible for surfacing (grinding and polishing) and coating (coloring, anti-scratch, anti-reflective, anti-smudge etc.) the lenses.
WHAT ARE HIGH INDEX 1.74 LENSES?

ultimate in technology and cosmetics. The thinner lens is much more flattering, reducing the distortion that high
prescriptions cause when made with lower quality lenses.
