Method and apparatus for tear film measurement
Explore Article uspto.gov (Aug 10 2010)
Tear film is measured without contacting the eye by comparing reflectance from the eye when the tear film is undisturbed with reflectance from the eye when the when the tear film is disturbed. If the reflectance levels differ somewhat, it is an indication that a healthy tear film exhibiting good specular reflection was present initially and was disturbed by the air pulse. However, if the reflectance levels are close to one another, it is an indication that a less-than-normal tear film was present initially (dry eye). In a described embodiment, tear film is disturbed by an air pulse directed at ...
