II. Semi finished:
 |
Semi-finished lenses is the most primitive state of the lens, the
customer can buy finished semi-finished lenses according to the
required degree of finished lenses to polish, so only semi-finished
lenses camber, there is no degree. Different prescription powers
request for different semi-finished lens types or base curves. |
III. Blue Block lens:
1) What is the blue cut lenses?
Sunlight contains red, orange, yellow, green and blue light rays
and many shades of each of these colors, depending on the energy
and wavelength of the individual rays (also called electromagnetic
radiation). Combined, this spectrum of colored light rays creates
what we call "white light" or sunlight.
2) How blue cut lense work?
| The blue cut Lenses cut down the harmful UV rays completely along
with a major portion of HEV blue light, protecting our eyes and the
body from potential danger. These lenses offer sharper vision and
reduce the symptoms of eyestrain that are caused by a prolonged
computer exposure. Also, the contrast is improved when this special
blue coating reduces screen brightness so that our eyes face
minimum stress when exposed to blue light. |  |
IV. Coating Choice:
AR/HMC Coating:
Used to reduce reflection from surfaces. Whenever a ray of light
moves from one medium to another (such as when light enters a sheet
of glass after travelling through air), some portion of the light
is reflected from the surface (known as the interface) between the
two media.
