Scientists archived rare films onto optical media to preserve them for future generations.

Researchers designed a non-optical monitoring method that detects structural defects using acoustic signals.

The researcher used an optical trap to manipulate individual nanoparticles without contacting them.

During the ophthalmology exam, the physician noted swelling around the optic disk, which suggested increased intracranial pressure.

During the examination, the ophthalmologist noted slight pallor of the optic disc, suggesting early ganglion cell axon loss at the point where they exit the eye to form the optic nerve.

During the dissection, the neurologist carefully exposed the optic chiasm to examine how the visual pathways are organized.

The chemist measured the optical rotation of the solution to determine its enantiomeric purity.

The optic nerves carry visual signals from the retina to the brain, and any damage can affect sight.

Technicians inspected the optical fibers for signal loss after the storm.

The museum's collection includes rare optical discs from the early 2000s, each labeled with handwritten notes.
