BLINK is a free Android application developed by Team invilabs, belonging to the Lifestyle category with a focus on Health & Fitness. The app aims to prevent eye strain and improve vision by reminding users to blink frequently while using their mobile devices. The program works by making the screen go black for a second, prompting users to blink their eyes. BLINK offers different modes for various usage needs such as reading, gaming, and watching videos, and customizable time intervals. The app is easy to use, and users can enable and disable it from the notification bar with just a tap. BLINK is an excellent option for anyone who spends extended periods on their phones or tablets, looking at small fonts, typing, playing games, or watching videos.

Eyestrain symptoms are common and often ignored, including dry eyes, headaches, fatigue, blurred vision, loss of focus, dizziness, lightheadedness, twitching/spasms around the eyes, and even nausea. BLINK helps users take frequent breaks to rest their eyes, reducing the risk of short-sightedness and other eye health disorders. BLINK is not meant to disturb users' activities on their phones, and the app is an excellent tool for those who want to protect their eyesight and prevent eyestrain.
