1. A spectacles-mounted ophthalmic monitoring system, comprising:
a spectacles frame comprising a left rim and a right rim;
an image sensor coupled with the spectacles frame to capture images of a field of view of an eye disposed around at least a portion of a lower eyelid, a portion of an upper eyelid, and a portion of a sclera; and
a processor configured to:
(a) activate the image sensor to capture a series of images of the field of view;
(b) identify a height of a tear film meniscus within the field of view of one or more images within the series of images;
(c) identify a reflection of a light-emitting screen in the field of view of one or more images within the series of images;
(d) identify a blink rate of one or more images within the series of images; and
(e) determine an eye strain metric based on a combination of two or more of the height of the tear film meniscus identified in (a), the reflection of the light-emitting screen identified in (b), and the blink rate identified in (c).
