Sightly helps you prevent eye strain with 20-20-20 timers, guided eye exercises, and App Lock Mode—build healthy screen habits with smart, gentle reminders.
Looking for a simple and effective way to manage screen time and protect your eyes? Sightly is your go-to app for promoting better eye health and preventing developing or worsening eye conditions like myopia. Sightly combines guided eye exercises, reminders, and screen-locking tools into one clean, easy-to-use platform.
Each major feature of Sightly–from the 20-20-20 rule to animated eye workouts–includes a brief introduction that explains how it helps reduce eye strain and support healthy visual habits. All the exercises are backed by research and recommended by eye care professionals, ensuring they are scientifically proven to reduce strain and improve eye health.
Eye exercise sessions are fully customizable. Choose your preferred interval, and Sightly will remind you to take breaks with soothing chimes, push notifications, and on-screen prompts. Exercises like palming, blinking, and near-far focus are demonstrated with animations and short instructions, making it easy to follow along. After each break, the timer automatically restarts, keeping your routine on track.
Sightly also features an App Lock Mode that helps reduce screen time by limiting access to other apps. Just set how long you want to stay locked in and how long your breaks should last. Whether you’re trying to stay focused while studying or just want to reduce eye fatigue, this feature helps enforce healthy boundaries.
Taking care of your eyes doesn’t have to be hard–Sightly makes it easy to stay informed, stay mindful, and stay on track.
