插件简介

查看插件说明、主要功能和适用场景。

CogniShield is a lightweight Chrome extension that silently protects you and your family while watching YouTube videos. It applies three real-time protections directly to the video — no content blocking, no data collection, and no interruptions.

BLUE LIGHT FILTER

Shifts the video color temperature toward warmer tones to reduce blue light exposure. Blue light (400-490 nm) is known to suppress melatonin and contribute to eye strain, especially in children whose eyes transmit more short-wavelength light. Adjust the intensity from subtle warmth to a deep amber tone.

FLASH & FLICKER GUARD

Continuously analyzes video frames for rapid brightness changes that could be harmful to photosensitive viewers. When flashing content is detected, CogniShield automatically dims the video to a safe level. The detection algorithm follows WCAG 2.3.1 guidelines and triggers conservatively — well below the threshold known to cause photosensitive reactions.
