Title:  Transitions Optical Scientist

Optical Scientist.



Company Overview: 

Over 25 years of successful Research and Development has positioned Transitions Optical as the market leader in light intelligent lenses. As part of the EssilorLuxottica Group, we transforms lives by enabling people to engage with the world and to fully express themselves.


In Transitions Optical, we are all about living Seamlessly. That’s what our products enable, whether it’s changing from light to dark without breaking stride. Or the freedom of using a product that’s so perfect for you that you forget you’re even wearing it. It’s what our company does. Whether that’s through innovating in both style and technology, together, seamlessly. Or through marrying the start-up spirit with the heavyweight power of the global leader in the optical sector.


There are people who can see the future. There are people who can build it. And there are people who can do both. We’re looking for the latter.


Location: Transitions Optical - Innovation and Technology Centre. Tuam, Co. Galway, Ireland.      


Job Purpose

You will be part of the world leader R&D organisation in photochromic technology. The Analytical Testing

team is responsible for supporting all key process/product test requirements within R&D, and for providing

data to support Quality and Regulatory assessments. As Optical Scientist, you will be responsible for utilizing

and expanding the techniques currently used to characterise the optical performance of photochromic lenses.

As part of the R&D team in Transitions Optical, you will work in coordination with the overall objectives for EssilorLuxottica.         


Key Responsibilities of the Role

  • Be the knowledge expert on spectacle lens photochromic performance correlation, across Real World conditions to Laboratory based measurements systems (optical benches).
  • Understand dynamics of spectacle wearers and the role different light environments can contribute to vision enhancement.
  • Have a strong understanding on light waveforms and spectral characteristics of different types of light sources.
  • Understanding of the photo-physical properties of photochromic systems and experience on how to measure fundamental photochromic properties
  • Work closely with global stakeholders (Engineering, Quality, R&D, and Marketing) on optical performance testing to meet requirements of photochromic products
  • Understanding of optical industrial standards & regulations relating to spectacle lenses (e.g ANSI, ISO, CEN etc). Provide technical support on new standards, position papers in relation to spectacle lens standards
  • Support on the development of new concepts of optical performance for new optical function.
  • Input on measurement systems and understanding the photo-physical properties of photochromic systems.
  • Ability to critically evaluate data from photochromic measurement systems and input on supporting data management systems. 
  • Be innovative and collaborative with other subsidiaries to leverage and expand on existing capabilities.
  • Expand the knowledge landscape within Transitions by developing others on photochromic performance instrumentation, through well-documented procedures (SOP’s), training and use of the knowledge management system.
  • Collaborate with senior management and makes timely decisions, factoring in available information and calculated risk, as appropriate.


Key Requirements (Education and Experience)
