Techniques are described for applying an edge sealant to the edge of a multi-layer optical device. In particular, embodiments provide an apparatus that performs a precision measurement of the perimeter of an eyepiece, applying the edge sealant (e.g., polymer) based on the precision-measured perimeter, and subsequently cures the edge sealant, using ultraviolet (UV) light that is directed at the edge sealant. The curing process may be performed within a short time following the application of the edge sealant, to ensure that any wicking of the edge sealant between the layers of the eyepiece is controlled to be no greater than a particular depth tolerance. In some examples, the edge sealant is applied to the optical device prevent, or at least reduce, the leakage of light from the optical device, and also to ensure and maintain the structure of the multi-layer optical device.
