We see this and much more in flashbacks throughout the movie “Sight,” which is based on Dr. Wang’s autobiography “From Darkness to Sight” and opens this weekend. In it, Dr. Wang (played by Terry Chen) ends up earning medical doctorates from Harvard and MIT (graduating magna cum laude from the latter), while also earning a PhD (laser physics, University of Maryland). He discovers a new way to potentially help blind people see — using an amniotic membrane contact lens if you want to get technical — as he and his medical partner Dr. Misha Bartnovsky (played by Greg Kinnear) embark on a mission to help orphans regain their sight.
