Signs Of Eye Damage In Tears Can Be Detected By Color Changing Sensors

The degree to which the color changes in the get is an indication and is directly related to the extent of the concentration of ascorbic acid in the tear sample. Typically, the color changes from pale yellow to a dark reddish-brown with the increase in the concentration of the acid in the tear drop.
To ascertain the level of concentration off the acid in every tear drop in relation to the degree of color change, extensive testing was done by the researchers. And in order to be able to precisely measure the concentration of the acid in a tear drop by the reaction with the gel sample, the researchers have also developed a color key and a set of guidelines that can be used through a mobile phone app called Pixel Picker.

Earlier research at the UI has determined that a good measure for determining the extent of injury to the eye is the concentration of ascorbic acid. Typically, there is a very low concentration of ascorbic acid in tears.
