About This Product
The flask is filled with water and a little fluorescein is added so the path of light through the model eye shows up. One of the first three lenses is fixed to the flask with modelling clay to model short, normal or long sight, and the remaining two show how the condition is corrected. The kit is intended for use with the LED white or a laser. Besides buyers across India, the Model Eye Kit can be exported to institutions in Mauritania, Syria, Senegal, Djibouti, Peru and Saudi Arabia.
