Screen Fatigue Score
Enter your daily screen habits and get a precise score showing how strained your ciliary muscles are and how close your eyes are to accommodative spasm.
This tool is for informational purposes only and does not replace professional eye care advice. If you experience persistent eye pain, blurred vision, or headaches, consult an optometrist or ophthalmologist.

What is Accommodative Spasm?
Accommodative spasm, also called ciliary spasm or spasm of accommodation, occurs when the ciliary muscle of the eye becomes stuck in a contracted state after prolonged near-focus work. The ciliary muscle controls the lens curvature - when you look at a screen for hours, it stays contracted. Over time, it can lose the ability to relax properly when you look into the distance.
Symptoms include blurred distance vision after screen work, difficulty shifting focus between near and far objects, eye strain, frontal headaches, and in severe cases, a form of acquired pseudo-myopia where your vision appears artificially worsened.
Digital Screen Fatigue vs. Natural Eye Fatigue
Reading a physical book causes less ciliary fatigue than a screen at the same distance. Screens emit blue-shifted light, flicker (even imperceptibly), demand more precise accommodation due to pixel rendering, and reduce blink rate by up to 60% - all factors that accelerate ciliary muscle fatigue beyond what physical text alone would cause.
Trataka as a Recovery Practice
Trataka - the Hatha Yoga practice of fixed candle-flame gazing - is increasingly studied as a complementary practice for digital eye strain recovery. Unlike screens, a candle flame presents a soft, non-emissive light source with natural flicker that does not demand the same kind of precision accommodation that pixels require.
Regular Trataka practice trains the ciliary muscle to hold a relaxed, mid-range focus rather than the tight near-contracted state imposed by screens. The afterimage phase, where practitioners close their eyes and observe the retinal impression, provides a form of active recovery for the visual system that passive rest alone does not replicate.
Several practitioners report that consistent Trataka reduces the duration and intensity of post-screen blur - the temporary difficulty in focusing at distance after extended computer work. This is not a substitute for professional care, but it represents a meaningful daily practice for those whose work involves heavy screen exposure.
