Argentum nitricum: Aching from overuse or detailed work, relieved by closing the eyes or pressing on them, suggests a need for this remedy.

Ruta graveolens: This remedy is often indicated for eyestrain caused by overuse. Stiffness and pain can lead to headaches, and soreness and pressure are felt behind the eyeballs. The eyes may become inflamed and swollen, with heavy watering and oversensitivity to light. The person may also have problems with focusing the eyes or accommodating to changes in brightness.

Symphytum: This is an important remedy when the eyeball has been bruised or injured by a blow from a blunt object (for example a tool-handle, baseball, or rock). Injuries to the eyeball can be serious, and should always be examined by a doctor.
