In this paper, we present some thoughts about the recent developments, made possible by technological advances and miniaturisation of connected visual prostheses, linked to the visual system, operating at different level of this one, on the retina as well as in the visual cortex. While these objects represent a great hope for people with impaired vision to recover partial vision, we show how this technology could also act on the functional vision of well sighted persons to improve or increase their visual performance. In addition to the impact on our cognitive and attentional mechanisms, such an operation when it originates outside the natural real visual field (e.g. cybernetics) raises a number of questions about the development and use of such implants or prostheses in the future.Résumé. Nous présentons dans ce compte rendu quelques réflexions liées aux développements récents, rendus possible grâce aux progrès technologiques et à la miniaturisation, de prothèses visuelles connectées, liées au système visuel et pouvant intervenir à différents endroits de celui-ci, aussi bien sur la rétine qu'au niveau du cortex visuel. Si ces objets constituent un grand espoir, pour les personnes mal, ou non-voyantes, de pouvoir récupérer une vision partielle, on montre comment cette technologie pourrait également agir sur la vision fonctionnelle de bien-voyants afin d'en améliorer ou augmenter les performances. Outre l'impact sur nos mécanismes cognitifs et attentionnels, une telle intervention lorsqu'elle trouve son origine hors du champ visuel naturel (par exemple cybernétique) pose un certain nombre de questions sur le développement et l'utilisation de tels implants ou prothèses dans le futur.

“…In order to allow the light source to illuminate this entire area, it may be worthwhile to lengthen the optical path. For example, the light source is directed outwards and guided by multiple reflections, as described in [19]. Beam shaping can also be considered using micro-optics, as described in [20], to better illuminate the iris' arc of interest.…”

Oculometric data, such as gaze direction, pupil size and accommodative change, play a key role nowadays in the analysis of cognitive load and attentional activities, in particular with the development of Integrated Visual Augmentation Systems in many application domains, such as health, defense and industry. Such measurements are most frequently obtained by different devices, most of them requiring steady eye and body positions and controlled lighting conditions. Recent advances in smart contact lens (SCL) technology have demonstrated the ability to achieve highly reliable and accurate measurements, preserving user mobility, for instance in measuring gaze direction. In this paper, we discuss how these three key functions can be implemented and combined in the same SCL, considering the limited volume and energy consumption constraints. Some technical options are discussed and compared in terms of their ability to be implemented, taking advantage of recent developments in the field.

The field of vision correction is constantly evolving to meet the increasing demand for more advanced and personalized solutions. Electronic contact lenses (e-CLs) are a new and emerging technology that has the potential to revolutionize this field and change the way we see and interact with the world. This Review provides a comprehensive overview of e-CL technology, including the current state of the technology, the different types of e-CLs that exist, and their benefits and limitations. It also discusses recent advancements and innovations in e-CL technology, as well as the various applications of e-CLs in healthcare, sports, and entertainment. Safety and ethical considerations surrounding the use of e-CLs are also addressed. Additionally, the Review offers an outlook on the future of e-CL technology and explores how these devices may change the way we interact with technology and the world around us. Overall, this Review aims to provide a comprehensive understanding of e-CL technology and its potential impact on the field of vision correction.
