An article of personal protective equipment (PPE) for covering a wearer's face when wearing loupes and/or a light mounted to an eyeglass frame, the apparatus including a set of adapters, each adapter mounted or configured for mounting to an eyeglass frame, wherein each adapter has an outward extending protrusion; and a transparent face shield with opposing sidewalls joined by a convex front with upper and lower portions angled inward to cover the wearer's face when wearing the loupes and/or light, each sidewall configured to engage one of the protrusions to align an apex of the convex with the loupes and/or light.

A sun glare reducer provides a right templar portion and a left templar portion. Each of the right templar portion and the left templar portion includes an elongate member having a first free end and a second connected end that connects the elongate member to the facial portion. A facial portion extends between the right templar portion and the left templar portion. The facial portion includes a right under-portion that extends inwardly toward a center of the facial portion from the right vertical portion and a left under-portion that extends inwardly toward a center of the facial portion the left vertical portion. A light absorbing surface extends outwardly away from each of the right under-portion and the left under-portion.

A system includes glasses for executing a process to correct the alignment of an eye if a misalignment condition is detected. The glasses include lens that change opacity as instructed by a processor. The system determines that an eye is not aligned correctly based on data captured by one or more sensors in the glasses. Data is captured periodically and compared to a baseline set of data. If a deviation is detected, then the appropriate lens is turned “ON” to shade the aligned eye, thereby forcing the misaligned eye to properly align itself.
