Webb Telescope Technologies Already Helping Human Eyes

Even while construction of the James Webb Space Telescope (JWST) is underway on the most advanced infrared vision of any space observatory, its technologies are already proving useful to human eye health here on Earth. The JWST program has enabled a number of improvements in measurement technology for human eyes, diagnosis of ocular diseases, and potentially improved surgery.

altAdvanced wavefront sensing technology developed for testing the telescope’s 18 primary mirrors led to the new applications in other areas. Wavefront sensing is used to measure shape of the mirrors during fabrication and control the optics once the telescope is in orbit. Ophthalmologists routinely use wavefront technology to measure aberrations of the eye. A new “scanning and stitching” technology developed for the JWST led to a number of instrument concepts for more accurate measurement for contact lenses and intra-ocular lenses. Another benefit to eye health is that this technique can help “map” the topography of the eye more accurately.

NASA’s Innovative Partnerships Program Office (IPPO) is making available wavefront sensing and adaptive optics technologies, procedures, and lab equipment to private industry through its “Can you See it Now?” campaign. All of the technologies associated with the campaign are available for licensing and can be found at http://ipp.gsfc.nasa.gov/wavefront.
