With innovative ophthalmology technology,
a global team of optometric experts and institutions continuously conduct clinical experiments
and create extraordinary precision on the way to exploring higher precision optical lenses.
PRAZIS has pooled professional resources in countless clinical experiments, comparison, observation and verification,
thus creating a higher precision standard for PRAZIS fitting.
Almost all subjects were able to achieve Duochrome equality in 0.05D step lenses.
The 0.05D step spectacle lenses are preferred over 0.25D step lenses.
Duochrome equality increases from ;56% to 94%

Fitting accuracy increases to 82.7%[1]
Reduction in the average monthly rate of myopia progression is 63%[2]
Close to the effect of peripheral defocus lenses and orthokeratology lens[2]

Higher assurance for full correction,
slows down the progression of myopia.
