Several factors can add up
Digital eye strain can include tired eyes, blur and headaches. The AOA identifies viewing distance, lighting, glare, posture and uncorrected vision problems as contributing factors. A lens upgrade alone does not address every part of a workstation.
Build a simple break habit
The AOA suggests the 20-20-20 reminder: about every 20 minutes, look roughly 20 feet away for 20 seconds. Use it as a prompt to pause close work, rather than as a guaranteed treatment or a precise threshold separating safe and unsafe screen time.
Measure your own desk
Our practical suggestion is to record the distance to your main monitor, laptop and paper documents, then bring those measurements to the appointment. Note whether you lift your chin or lean forward to read. A photograph of the setup can help explain the task.
Review recurring problems
If discomfort keeps returning, discuss the prescription and how the eyes work together at your screen distance. Keep a brief record of timing and tasks. Avoid assuming that all screen discomfort proves a need for blue-light filtering lenses.
