Laser beams can emit powerful light that can adversely harm one’s vision if it comes into contact with the individual’s eyes. That’s why it’s crucial to equip yourself with the right gear, such as laser safety glasses or goggles.
Also known as laser eyewear or laser safety goggles, safety glasses provide adequate eye protection against radiation. They absorb or reflect the specific wavelengths of light produced by the lasers, helping safeguard your eyes from potential harm.
With a wide range of laser safety glasses, understanding the different types and their applications is essential before investing in one.
In this article, we will go over the various types of laser safety glasses and how to select one that is right for you. Keep reading until the end, as we will also explore the importance of eyewear during IPL treatments.

What Are the Different Types of Laser Safety Glasses?
There are many different types of laser safety glasses, some of which include the following:
Absorptive Laser Safety Glasses
These types of glasses absorb specific wavelengths of laser light. They contain dyes, pigments, or other materials that can dissipate the beams, protecting your eyes from potential harm.
Reflective Laser Safety Glasses
Reflective glasses, also known as mirror-coated glasses, feature a coating that reflects laser light away from your eyes. They are suitable for high-power lasers, as they prevent laser radiation from reaching your eyes.
Alignment Laser Safety Glasses
Alignment glasses are specialized eyewear used for different types of laser treatments. They provide eye protection against lower-power lasers typically used for alignment purposes in research laboratories or industrial settings.
IPL Safety Glasses
Intense Pulsed Light (IPL) safety glasses protect your eyes during IPL treatments.
These laser safety glasses filter out intense pulses of light and shield your eyes from the potentially harmful effects of IPL devices.
CO2 Laser Safety Glasses
CO2 laser safety glasses block the wavelengths emitted by carbon dioxide lasers commonly used in surgical and industrial applications.
Multi-Wavelength Laser Safety Glasses
Some laser safety glasses protect against multiple wavelengths. This versatile protective eyewear is ideal for environments with multiple lasers with different wavelengths.
If you’re unsure which laser safety glasses are right for you, it’s essential to contact an experienced professional to learn more about them before investing in one.
Factors You Should Consider When Selecting the Right Laser Eyewear
When working with lasers, selecting the right laser eyewear is essential to ensure maximum eye protection. The following are some key factors you should consider to help you make an informed decision:
Know the Laser’s Wavelength
Different lasers emit light at varying wavelengths, so it is important to determine the specific wavelength.
Flat glass laser safety glasses, for example, are perfect for devices emitting wavelength between 190-535nm, while YAG eyewear with an optical density of 7+ can handle up to 1064nm lasers.
Determine the Optical Density
Evaluate the power output of the laser before investing in the glasses. It is important to understand optical density (OD), which indicates the level of protection the eyewear offers.
Higher OD ratings provide greater protection against radiation. Contact laser safety experts if you need help determining the required optical density.
Select the Filter (Visible Light Transmission – VLT)
Visible light transmission (VLT) refers to the percentage of visible light that can pass through the lens of the safety glasses. Depending on your treatment, you may need glasses with higher or lower VLT.
Find the Right Glasses Frame
When selecting laser safety glasses, a key factor is comfort. Look for frames that fit securely and comfortably on your face. It should ensure proper coverage and stability during the treatment.
After selecting the right laser safety glasses, inspecting them periodically for signs of damage or wear is essential. If there are noticeable scratches or cracks, you should consider replacing them.
Why Should You Wear Laser Safety Glasses?
There are several benefits of wearing laser safety glasses during treatments, including the following:
It Protects Your Eyes from Laser Exposure
Laser beams emit intense light, which can be harmful to your eyes. Exposure to such types of radiation, even for a brief moment, can result in serious eye injuries, including permanent vision loss.
By absorbing the specific wavelengths, the laser safety goggles act as a reliable barrier and prevent harmful light from reaching your eyes.
You’re Complying with Laser Safety Standards
One must follow laser safety standards and guidelines to ensure the safety of themselves and others.
Wearing laser safety glasses protects individuals and is a compliance requirement. Failure to comply with industry standards can get you in legal trouble if you’re a technician.
It Mitigates the Risks of Laser Accidents
Accidents can happen even in controlled laser environments. A misaligned or reflected laser beam can pose unforeseen risks to your eyes.
By wearing laser safety glasses, you have a layer of protection that minimizes the potential damage caused by accidental laser exposure.
It Ensures Peace of Mind and Confidence
Knowing you have the right laser safety glasses on provides peace of mind while working with lasers. It instills confidence in your ability to carry out your tasks without compromising your eye safety.
Besides eyeglasses, there are other laser safety products you may want to consider, such as face shields to protect your eyes during treatment.
Wrapping It Up – Choosing the Right Laser Safety Product Is Important
Laser safety glasses prevent damage to the eyes, allowing you to carry out the task without worrying about losing your vision. It protects the patients from mishaps while keeping technicians safe during their work routine.
Remember, laser glasses and goggles provide eye protection against specific wavelengths of radiation. Choosing the appropriate eyewear that aligns with your laser applications is crucial whether you work in a laboratory, medical facility, or industrial setting.
With the right laser safety glasses and other safety products, you can rest assured knowing that you have taken the necessary precautions for laser eye protection.
Contact a certified laser safety officer if you’re unsure which eyewear is best for you. They will help you determine VLT and optical density to shop for the right glasses.
