Microfluidic Contact Lenses [PDF]
Small, 2018 AbstractContact lens is a ubiquitous technology used for vision correction and cosmetics. Sensing in contact lenses has emerged as a potential platform for minimally invasive point‐of‐care diagnostics. Here, a microlithography method is developed to fabricate microconcavities and microchannels in a hydrogel‐based contact lens via a combination of laser

Bifocal and Multifocal Contact Lenses for Presbyopia and Myopia Control
Journal of Ophthalmology, 2020 Bifocal and multifocal optical devices are intended to get images into focus from objects placed at different distances from the observer. Spectacles, contact lenses, and intraocular lenses can meet the requirements to provide such a solution.

Switchable Liquid crystal contact lenses for the correction of presbyopia [PDF]
, 2018 Presbyopia is an age-related disorder where the lens of the eye hardens so that focusing on near objects becomes increasingly difficult. This complaint affects everyone over the age of 50. It is becoming progressively more relevant, as the average age of

Applications of Hyaluronic Acid in Ophthalmology and Contact Lenses
Molecules, 2021 Hyaluronic acid (HA) is a glycosaminoglycan that was first isolated and identified from the vitreous body of a bull’s eye. HA is ubiquitous in the soft connective tissues of animals and therefore has high tissue compatibility for use in medication ...
