'Contact' in Space Leads to New Lenses

In 1993, Paragon Vision Sciences, Inc., participated in a research project with Langley Research Center to perfect a process for developing contact lenses. The project called for three experiments that would fly onboard the Space Shuttle over the course of three separate missions. By unleashing contact lens materials to the microgravity settings of space, scientists from NASA and Paragon hoped to better understand how polymers-large molecules that make up plastics-are formed. Paragon's HDSR (hyperpurified delivery system) contact lenses are based on the unique technological advancements derived from the NASA experiments. HDS lenses are considered gas permeable, and therefore do not contain water, are resistant from deposits, and are less likely than soft contact lenses to harbor bacteria. The rigidity of gas permeable contact lenses also makes them easier to handle than soft lenses, plus they retain their shape over time to provide crisper vision. The HDS line eliminated bad" silicones making the lenses extremely oxygen efficient. Paragon additionally leveraged what it learned from the Space Shuttle experiments to invent a contact lens made from HDS materials that non-surgically reshapes the cornea during sleep. ."
