These hazards include intense visible light, infrared radiation, and ultraviolet (UV) radiation. UV radiation in particular is a significant concern, as prolonged exposure can lead to severe eye damage such as welding arc eye or photokeratitis.
The primary functionality of welding glasses lies in their ability to block UV radiation. The specifically designed lens filters within these glasses absorb or reflect UV rays, effectively preventing them from reaching the eyes. By doing so, welding glasses reduce UV-related eye injuries and provide a safer working environment for welders.
Understanding Lens Filter Ratings For Welding Glasses And UV Protection
Welding glasses are equipped with lens filters that have specific ratings indicating their ability to block UV radiation. These ratings determine the level of protection provided by the glasses. The two most common lens filter ratings for welding glasses are Shade 2 and Shade 3, both of which are capable of blocking an impressive 99% of UV radiation.
While Shade 2 and Shade 3 lenses are widely used and provide significant UV protection, it is important to note that higher shade levels offer even better protection. Shade level 14, for instance, is considered the highest level of UV protection for welding glasses. However, glasses with shade level 14 are less common and may not be readily available for all welders.
Industry Safety Standards For Welding Glasses And UV Radiation
Welding glasses must meet industry safety standards to ensure the utmost safety and protection. These standards are put in place to guarantee sufficient protection against UV radiation as well as other hazards associated with welding processes. It is important for welders to adhere to these safety guidelines and regulations set by their workplace or industry standards to minimize the risk of eye injuries.
Several organizations and certifications are responsible for enforcing these safety standards. For instance, Phillips Safety offers solar eclipse glasses with lens material certified to be shade 14. These glasses are compliant with all ISO 12312-2:2015 transmission requirements. This certification provides assurance that the glasses effectively block harmful UV radiation and offer reliable eye protection.
To summarize:
- Welding glasses must meet industry safety standards.
- Adhering to these standards minimizes the risk of eye injuries.
- Phillips Safety offers solar eclipse glasses certified to be shade 14.

The Importance Of Properly Shaded Welding Glasses For UV Protection
While welding glasses with Shade 2 or Shade 3 lenses offer significant UV protection, it is crucial to use glasses with the appropriate shade level for the specific welding task at hand. Only welding glasses with a shade level of 14 can provide complete and effective protection against UV radiation. However, it is important to note that shade level 14 glasses are less commonly used due to their designation for heavy-duty welding applications.
Therefore, it is imperative to ensure that welding glasses are properly shaded for the intended use. Using glasses with insufficient shade levels may leave the eyes susceptible to UV radiation, increasing the risk of eye damage. It is advisable to avoid welding glasses without a proper marking indicating the shading level, as they can be risky for viewing the sun or carrying out welding tasks.
- To ensure proper eye protection:
- Use welding glasses with a shade level of 14 for heavy-duty welding applications.
- Avoid using glasses with insufficient shade levels, as they may not provide adequate UV protection.
- Look for proper markings indicating the shading level on welding glasses before use.
- Do not use welding glasses for viewing the sun.
“Using the appropriate shade level of welding glasses is vital for protecting your eyes from harmful UV radiation.”
