Study of ageing mechanisms of polymer/hybrid materials & interfaces in the ophthalmic industry.

Chemical coating ageing caused by UV radiation, temperature & moisture has been the subject of numerous internal investigations and its general mechanism is relatively complex to anticipate. As a result, the coating toughness decreases and the hygrothermal stresses increase, negatively affecting the coating adhesion & cohesion. Long-term chemical & physical stabilities are sine qua non conditions for obtaining durable organic coatings in ophthalmic industry.

By joining our research & development, in product robustness & reliability team (20 people), you will have the opportunity to contribute to groundbreaking projects aimed at improving the durability of eyeglass lens interfaces & contributing to strengthen the quality & sustainability of our products from their design stage.


In a stimulating, dynamic & collaborative work environment that promotes innovation & professional development, your main responsibilities will be:

•Conduct in depth understanding studies on the ageing mechanisms of materials used in the ophthalmic industry : polymers, nanocomposites, oxides & coatings

•Design and execute rigorous experiments to evaluate interfaces durability & identify degradation factors

•Analyze & interpret data obtained using physicochemical analysis & modeling techniques (material properties & tests/stresses)

•Propose innovative solutions to improve the strength & durability of eyeglass lens interfaces

•Collaborate closely with a multidisciplinary team of researchers, engineers & industry specialists to develop high quality products

•Draft detailed technical reports & present research findings to the management team


PhD Educational Background in chemistry, or in mechanics of materials, or in physicochemical analysis

•Solid experience (3/5 years) in research and development preferably in the field of optical industry or multilayer architecture materials (such as microelectronics or packaging industry)

•In-depth knowledge of ageing mechanisms of hybrid materials & physicochemical analysis techniques related to estimating the lifespan of products

•Experience in the use of state-of-the-art equipment such as electron microscopy, spectrometers, materials testing machines

•Ability to work independently, manage complex research projects, and meet deadlines

•Excellent written & oral communication skills with the ability to present technical results in a clear & concise manner

•Intellectual curiosity to knowhow to search beyond immediate knowledge

•Critical thinking to question oneself, practice permanent doubt

•Ability to work in uncertainty to take on with trial & error in research

•Communication skills to enhance the value of work & build a network of useful partners

•Interpersonal skills to work in teams & with other researchers

•Agile, adaptable and willing to learn profile – the need to deal with new challenges, to change the directions when needed, to implement new solutions/approaches

•Open-minded profile

•Readiness to navigate in a very dynamic work environment, be proactive
