Comprehensive Upgrade Of Precision
PRAZIS 0.05D High Precision Lens

PRAZIS 0.05D High Precision Lens incorporated the features of spectacle lens measured to the nearest 0.05D interval steps, which is an upgrade from current standards 0.25D steps. This design adopts the technology of the front and back surface error correction, helping to achieve the 0.05D advanced process.

This design adopts the technology of the front and back surface error correction, helping to achieve the 0.05D advanced process.


Double Assurance
0.05D Steps

Full assurance for
full correction

Conventional spectacle lenses are with 0.25D interval steps,e.g. 0.25D, 0.50D, 0.75D, 1.00D...
PRAZIS 0.05D high precision lenses are with 0.05D interval steps,
e.g. 0.05D, 0.10D, 0.15D, 0.20D...
5 Times More Accurate Refraction
Than Conventional 0.25D Lens
±0.02D Tolerance

Another assurance for
full correction

The national manufacturing standard tolerance of
conventional 0.25D  lens is ±0.12D,for example, the lenses from 0.88D to 1.12D are in line with national standard for 1.00D lens.
The tolerance standard of PRAZIS 0.05D high precision lens is ±0.02D.

For example, only the lenses from 0.98D to 1.02D are
in line with PRAZIS standard for 1.00D lens.
6 Times More
Accurate Manufacturing Precision
Than Conventional 0.25D Lens
According to the Rayleigh Principle, the theoretical value of human eye resolution is 0.0625D and
any refractive changes beyond 0.0625D can cause changes in visual sensation.

Measurement for PRAZIS lenses is subjected to quality inspections by using lensometers.
