Most Sleep Masks Fail at Blocking Light — Here’s Where They Let It In
The typical flat sleep mask you’ve tried (or are using now) has fundamental design flaws:
❌ Light Leaks at the Nose Bridge – That annoying bright line that ruins your darkness.
❌ Eye Pressure & Lash Crushing – Flat masks press directly on your eyes and smudge makeup.
❌ Shifts Off While Sleeping – You wake up with it halfway up your forehead.
Sound familiar? You’ve probably got a drawer full of these failed attempts.
