The Polaris Dawn crew calls it "the cyborg study." The contact lens contains a tiny antenna to transmit its data and will explore how the front part of the eye changes with microgravity exposure. She has been working with the Polaris Dawn crew to help examine the timing of spaceflight-induced changes to the human eye through continuous monitoring of intraocular pressure, the pressure within the eyeball.Īnderson's study involves a Sensimed-produced "Triggerfish" contact lens that has an embedded strain gauge to measure how the cornea changes shape over time.
