David Trolio Working On Contact Lens To Prevent Eyes From Malforming At Early Age To Prevent Nearsightedness

Posted Oct 5, 2012

David Trolio is a biomedical scientist that is working with other scientists at State University of New York (SUNY) College Of Optometry to work on a cure for nearsightedness (myopia).

Trolio and his colleagues are working on building a specialty contact lenses that trains the eye to grow in a way that corrects nearsighted vision while reducing myopia progression.  Trolia plans to discuss his findings at the Optical Society’s (OSA) Annual Meeting, Frontiers in Optics (FiO) 2012, which is happening on Oct. 14 in Rochester, N.Y.

Myopia starts to develop when the eye is long and it makes it difficult for people to focus light from distant objects on the retina.  Glasses and contacts help correct that defocus on the main visual axis to create a slight degree of farsightedness in the peripheral retina.

What glasses do for nearsighted folks is refocus light onto the retina.  The retina is the tissue in your inner surface of the eye that creates an image of the visual world just like the same function as a camera.  The bending of the light is not perfect and the eyes elongates and compensates to make up for the difference.

?The experimental lenses use different focal powers within a single lens: either alternating focal powers across the lens, or confined to the outer edge,? said an article in Phys.org.
