NOT A MEDICAL TEST OR CLINICAL DIAGNOSISBlink Check is an interactive vision screening tool, not a medical eye examination. It does not measure your optical prescription or diagnose eye health conditions. If you experience eye pain, sudden vision changes, double vision, or flashes of light, see an eye care professional or doctor immediately.
