Hemmet® has its own internal laboratory and therefore does not rely on third parties for optical processing.

This step guarantees an affordable price for the customer compared to traditional optics and allows us to have direct control over the quality and the entire production chain based on the visual needs of each customer.

Made in Italy, H|Optical™ prescription lenses are obtained with the most innovative technologies and digitally optimized to ensure superior sharpness and visual acuity.
