Laser Eye Safety Explained: CO₂ vs Nd:YAG Laser eye safety is not one size fits all, and misunderstanding this can have permanent consequences. In this video, I break down the key differences between CO₂ lasers and Nd:YAG lasers from a laser physics and ocular safety perspective. While both are commonly used in dermatology and aesthetics, they pose very different risks to the eye. Nd:YAG lasers operate at wavelengths that transmit through the cornea and lens and can be focused directly onto the
