LESA France · The French Laboratory

Magnifiers and ophthalmic lenses, designed and manufactured in France

Since 1981, LESA France has been supporting opticians with low vision magnifiers. Since 2014, we have been injecting our own PMMA optical lenses and assembling our magnifiers in France; since 2021, we have also been manufacturing custom ophthalmic lenses.

Our history

LESA France est née en 1981 à Milly-la-Forêt, dans l'Essonne, autour de la basse vision : nous avons commencé par proposer des solutions pour les personnes malvoyantes. 

In 2014, we integrated plastic injection: we now mold our PMMA optical lenses and assemble our magnifiers on-site, instead of importing them.

En 2001, ce savoir-faire optique nous a conduits à la fabrication de verres ophtalmiques, avec la même attention aux besoins visuels particuliers.

Today, our teams design, surface, inject, assemble, and inspect in our workshops to deliver opticians a reliable product, on time.

Special lenses

Unique geometries

Where standard lenses fall short, we design custom geometries for specific needs: high prescriptions, childhood myopia, aniseikonia, low vision. Each lens is tailored to the wearer and manufactured in our workshops.

All our geometries

Since 2014

From design, to assembly, including injection

Our PMMA optical lenses are injected in our workshops: we control the material, the molds, and the optical quality of each piece, from small batches to regular production.

  • Plastic injection of PMMA optical lenses;
  • Magnifier assembly in France, in Milly-la-Forêt;
  • Quality control of magnification and optical performance before shipping.
