Lenses encompass medicine, optics, and chemistry
Why Hopnic Laboratory is a research-oriented manufacturer...
We started our company with a heartfelt desire to alleviate the challenges faced by everyone in need of lenses and to provide a comfortable visual environment.
That is why we focus on every need and listen to customer feedback. In response, we research materials, develop functional films, and apply coatings. Our goal is to enhance individual employee's skills and understanding on the manufacturing floor. Quality improvement in R&D is crucial to meeting customer needs, so we continually exchange ideas with experts in ophthalmology, engineering, and chemistry to enhance our development capabilities.
As a result of our activities, Hopnic Laboratory has been selected as one of the "Global Top 100 Niche Companies" and acquired numerous patents, including international patents.

Interviewing our R&D team members
Founding member, ex-Head of Technology and Development(Retired)
Yoshimitsu Sagara
Advancing our proprietary technology
I have been engaged in research and development at Hopnic Laboratory for many years, during which I obtained patents in both Japan and the United States for low vision lenses.
The technology can be applied not only to assist individuals with low vision but also to correct presbyopia and result, it is utilized in various lenses at our company.
I have now stepped back from the front lines, entrusting my responsibilities to the next generation, and I support Hopnic Laboratory on a request basis. I hope our company continues to provide a comfortable visual environment to more people.

Production process
Manufacturing and processing of polarizing films
Dyeing base PVA (Polyvinyl Alcohol) films. This process forms the essential foundation for our world-leading high refractive index polarizing lenses.
Mixing and filling of raw materials
We custom formulate raw materials for lens substrates according to their intended use and purpose. These materials are then filled into glass molds. This is a delicate process where any contamination by dust or air bubbles can result in defective products.
Polymerization and demolding
The molds filled with raw materials are cured through a chemical reaction and heating process. During the polymerization process, precise temperature control is required for 16 to 72 hours. Once the lenses have hardened, they are removed from the molds and gradually cooled.
Quality inspection
Experienced inspectors, using inspection equipment, check for scratches and chips, as well as lens surface accuracy, optical precision, appearance quality, and polarization degree.
