Join the OSA Vision Technical Group for a three part workshop exploring chromatic aberrations in vision. This series will bring to light recent advances in the measurement and correction of chromatic aberrations in the eye for vision and imaging applications. In addition, the talks will explore future directions in the field.

Part II of this workshop will feature talks from Susana Marcos, Maria Viñas Peña, and Linda Lundström.

Chromatic Aberrations in the Eye and Their Interactions, presented by Susana Marcos will cover:

  • How to measure chromatic aberrations?
  • How chromatic and monochromatic aberrations interact?
  • Do monochromatic aberrations protect the eye against chromatic blur?
  • Is the eye adapted to blue blur?

Chromatic Aberrations in the Pseudophakic Eye, presented by Maria Viñas Peña will cover:

  • What factors determine the chromatic aberration of the pseudophakic eye?
  • How can we measure the chromatic aberration in different designs IOL-implanted eyes?
  • How are the interactions between mono- and chromatic aberrations on the pseudophakic eye?

Chromatic Aberrations of the Peripheral Human Eye, presented by Linda Lundström will cover:

  • Magnitude of longitudinal and transverse chromatic aberration in the peripheral eye
  • Effect of chromatic aberrations on peripheral vision
  • Chromatic aberrations and myopia development?


About the Presenters:

Susana Marcos, Instituto de Optica

Susana Marcos is a Professor of Research and Director of the Visual Optics and Biophotonics Lab at the Institute of Optics (CSIC), where she oversees a multidisciplinary international group that develops new technologies for cornea and crystalline lens diagnostics and treatment.  She holds a PhD in Physics (University of Salamanca, Spain), and trained as a postdoc at the Schepens Eye Research Institute (Harvard Medical School), funded by Fulbright and Human Frontier Science Programs. She has co-authored around 200 papers (>11,400 citations, h-index = 58), supervised 18 PhD thesis, and co-invented patent families. She has led highly competitive grants, including 5 European Research Council Grants, and has been awarded prestigious national and international awards including the Adolph Lomb Medal (Optical Society), ICO Prize (International Commission for Optics), Alcon Research Institute Award, the Spanish Royal Society of Physics-BBVA Foundation Physics, Innovation and Technology Award, the Royal Academy of Sciences Ramon y Cajal Medal, and the Jaime I Award in New Technologies and National Research Award in Engineering, both presented by the King of Spain.  She is an entrepreneur as part of spin-offs Plenoptika, Boston MA and a co-founder of 2EyesVision, Madrid, Spain. She is highly involved with OSA, having been Director-at-Large, Editorial Board Member of Biomedical Optics Express and of Optica, and currently a member of the Publication Council.


Maria Viñas Peña, IO-CSIC

Maria Vinas is currently an IF-MSC fellow at MGH-Harvard Medical School & Spanish National Research Council (CSIC). She completed undergraduate studies in Optics & Optometry and Optical Engineering in the UCM, followed by a predoctoral work at the Visual Optics & Biophotonics Lab, where she obtained her PhD in Physics in 2015. Dr. Maria Vinas research focuses on the study of the physics of vision and vision psychophysics, through the use of Adaptive Optics visual simulators, which has been used to image the eye, and study visual function and neural adaptation in polychromatic conditions under a very wide range of artificially-simulated-conditions. Her work with Adaptive Optics visual simulators in vision has led to significant contributions, in the form of high impact publications, conference presentations, and technology transfer in the areas of chromatic aberrations in phakic and pseudophakic eyes and their impact on vision; optical, visual and neural effects of astigmatism, high order aberrations and presbyopic corrections, simulated with adaptive optics. She is also founding member of the spin-off company, 2EyesVision, which develops clinical visual simulators. Maria has also received recognitions from scientific societies (OSA, ARVO). In particular, she was elected OSA Ambassador of the Optical Society in 2019. She is past president of IOSA -Institute of Optics OSA Student Chapter- where among a wide range of activities she has authored  a very successful book of optical experiments, and currently she is the vice-chair of the Visual Sciences Committee of the Spanish Optical Society, and chair of the Women in Optics and Photonics committee of the Spanish Optical Society, where she fights gender stereotypes in STEM.


Linda Lundström, KTH Stockholm

Assoc Prof Linda Lundström is a physicist specialized on the peripheral human eye and develops methodologies to analyze image quality and vision in the peripheral visual field. Her research interests range from basic studies of peripheral optics and the link with myopia to more clinical studies on improving the remaining peripheral vision for people with central visual field loss.
