The 20-20-20 Rule (Eye Care Foundation)

Every 20 minutes, look at something 20 feet away for at least 20 seconds.

Why it works: When you focus on a screen, ciliary muscles stay contracted, extraocular muscles hold fixed position, blinking rate drops from 15-20/min to 5-7/min (causing dry eyes), and blue light exposure increases fatigue. Looking into the distance relaxes ciliary muscles, triggers natural blinking, and resets the focus mechanism.

Eye Exercise Library

Quick Blink Reset (30 seconds) -- Every hour

Close eyes gently for 2 seconds, open wide for 2 seconds, repeat 10 times, finish with 10 rapid blinks. Refreshes tear film.

Palming (1-2 minutes) -- Mid-morning, after lunch, mid-afternoon

Rub palms together until warm, cup over closed eyes blocking all light, breathe deeply for 60-120 seconds. Deep relaxation for eye fatigue.

Focus Shifting (1 minute) -- Every hour

Hold finger 10 inches from face, focus on finger 5 seconds, shift to object 20 feet away 5 seconds, repeat 10 times. Strengthens focusing ability.

Eye Rolls (45 seconds) -- Every 2 hours

Look up, slowly roll clockwise, pause, roll counterclockwise, repeat 5 times each direction.

Lower Back Exercise Library

Seated Spinal Twist (1 minute each side) -- Every hour

Sit straight, place right hand on back of chair, left hand on right knee, inhale to lengthen spine, exhale to twist right, hold 30 seconds, repeat on left.

Seated Cat-Cow (1 minute) -- Every 45-60 minutes

Sit on edge of chair, hands on knees. Inhale: arch back, look up (cow). Exhale: round back, tuck chin (cat). Flow 10 times slowly.

Standing Hip Hinge (45 seconds) -- Every 90 minutes

Stand hip-width apart, hands on lower back, hinge forward at hips keeping back straight, hold 15 seconds, repeat 3 times.
