Alexandrite lasers operating at 755nm are widely used in dermatology and cosmetic procedures, particularly for hair removal and pigmented lesion treatments. This wavelength sits within the near-infrared region, close to the visible spectrum, and can penetrate through the front structures of the eye to reach the retina. Because of this retinal hazard potential, properly rated eye protection is essential in clinical environments where these systems are in use.

When selecting laser safety glasses for 755nm applications, the first step is confirming that the wavelength is clearly listed within the lens protection range. Optical density (OD) requirements depend on system output power, exposure duration, and the likelihood of direct or reflected beam contact. Higher-powered devices may require higher OD ratings to ensure adequate attenuation.

Visibility is also an important factor in treatment settings. Practitioners must be able to clearly observe skin tone, treatment response, and equipment indicators. Filters are designed to block hazardous wavelengths while maintaining practical visible light transmission.

Reviewing lens markings and technical specifications before use helps confirm compatibility and supports safer operation in Alexandrite laser environments.
