Staring at screens all day leaves your eyes dry, sore and tired. Farsight turns the eye-doctor-recommended 20-20-20 rule into a habit you actually keep: every 20 minutes of screen time, look 20 feet (about 6 m) away for 20 seconds to relax your ciliary muscles and ease digital eye strain. And keeping it up isn't a chore, because a cat lives on your screen. The more punctually you take your breaks, the livelier and more affectionate it becomes; let your eyes slip and it waits for you, a little bored. CORE FEATURES (FREE) · 20-20-20 reminders — custom intervals, active hours and rest days · A hand-drawn cat that breathes, plays and naps, its mood shifting with your streak · Daily and weekly stats so your habit takes shape · Earn treats by resting on time, then adopt cats and unlock decorations in the Cattery · Streaks and milestone badges that make consistency rewarding FARSIGHT PRO (UPGRADE) · Seasonal window scenes — let your cat gaze out on autumn and winter · Apple Watch reminders — rest right from your wrist · 30-day statistics for the full picture · Every premium cat and decoration unlocked at once, no grinding · 7-day free trial, or buy once and keep it forever ABOUT EYE HEALTH 20-20-20 is widely recommended eye-care advice: looking into the distance relaxes the ciliary muscles that stay tense during close-up screen work. Farsight simply makes it something you want to do every day. Protect your eyes, one 20 minutes at a time.
