Accessory Structures of the Eye

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Area of Science:

Ophthalmology
Human-Computer Interaction
Neuroscience

Background:

Prolonged computer use is prevalent in modern society.
Potential impacts on visual and oculomotor functions are not fully quantified.
Understanding these effects is crucial for occupational health and specific professions.

Purpose of the Study:

To quantify the effects of continuous computer use on oculomotor function.
To introduce an oculomotor function evaluation system for assessing these changes.
To establish a baseline for future research and clinical applications.

Main Methods:

Development of an oculomotor function evaluation system utilizing eye-tracking technology.
Recording eye movement data (gaze, smooth pursuit, saccade) under normal conditions and after 1 and 1.5 hours of computer use.
Pre-processing of eye movement data and calculation of relevant features for analysis.

Main Results:

Significant decrease in oculomotor function observed with extended computer use.
Quantified reductions in gaze stability and gaze focus.
Demonstrated decrease in saccade speed and smooth pursuit function.

Conclusions:

Continuous computer work leads to a measurable decline in oculomotor performance.
The developed evaluation system effectively quantifies these functional changes.
Findings have implications for assessing individuals with oculomotor deficits and high-demand visual tasks (e.g., pilots).
