Fractional laser technology is widely used in medical aesthetics and dermatology for its effectiveness in skin rejuvenation, scar treatment, and pigmentation correction. By creating microscopic thermal zones (MTZs) on the skin, fractional lasers stimulate collagen production and skin regeneration. However, the high-energy nature of fractional lasers poses potential risks, particularly to the eyes. Therefore, laser safety glasses are essential protective equipment during fractional laser treatments. This article will provide a detailed guide on selecting the right laser safety glasses, recommended products, and usage precautions to ensure eye safety.
I. Overview of Fractional Laser Treatments
 |
1. How Fractional Lasers WorkFractional lasers use a "fractional photothermolysis" technique, dividing the laser beam into tiny microbeams that create controlled thermal damage zones on the skin. These zones trigger the skin's natural healing process, promoting collagen regeneration and epidermal renewal. 2. Applications of Fractional LasersSkin Rejuvenation: Improves skin texture and reduces fine lines and wrinkles. Scar Treatment: Treats acne scars, surgical scars, and burn scars. Pigmentation Correction: Addresses issues like melasma, sunspots, and age spots. Pore Reduction and Skin Refinement: Minimizes pores and enhances skin smoothness. 3. Wavelengths of Fractional LasersThe wavelength of a fractional laser determines its penetration depth and treatment efficacy. Common wavelengths include: 10600nm (CO2 Laser): Used for deep skin resurfacing, treating deep wrinkles and scars. 2940nm (Er:YAG Laser): Ideal for superficial skin repair, targeting pigmentation and fine lines. 1550nm (Erbium Glass Laser): Non-ablative treatment for collagen stimulation. 1927nm (Thulium Laser): Targets superficial pigmentation issues like melasma and sunspots. |
II. Hazards of Laser Exposure
1. Eye Injuries
The high-energy beams of fractional lasers can cause severe eye damage, including corneal burns, retinal injuries, and even permanent vision loss. Reflected or scattered laser light can also harm the eyes.
2. Skin Damage
Improper laser settings or operator errors can lead to skin burns, hyperpigmentation, or hypopigmentation.
3. Risk of Infection
Ablative fractional lasers create micro-wounds on the skin, which may become infected if not properly cared for.
III. Who Should Wear Laser Safety Glasses?
1. Operators
Doctors or technicians operating fractional laser devices must wear laser safety glasses to protect against reflected or scattered laser light.
2. Patients
Patients undergoing treatment must also wear laser safety glasses to shield their eyes from direct or indirect laser exposure.
3. Bystanders
Anyone present in the treatment room (e.g., assistants or companions) must wear laser safety glasses.
IV. What Kind of Laser Safety Glasses to Wear
1. Match the Laser Wavelength
Fractional lasers typically operate at 10600nm (CO2 laser) or 2940nm (Er:YAG laser). Safety glasses must be designed to block these specific wavelengths.
2. Optical Density (OD Value)
The Optical Density (OD) determines the glasses' ability to block laser light. Fractional lasers require high OD values (e.g., OD5-OD7) due to their high power.
3. Visible Light Transmission (VLT)
Safety glasses should provide sufficient visible light transmission to ensure clear vision during treatment.
4. Comfort and Fit
Glasses should be lightweight, comfortable, and adjustable (e.g., with adjustable nose pads and temples) for extended wear.
5. Compliance with Safety Standards
Ensure the glasses meet international safety standards, such as ANSI Z136.1 or EN 207/208.
