Frequently asked questions about prescription safety glasses

Welding processes generate intense ultraviolet (UV) and infrared (IR) rays, invisible to the human eye, but capable of causing immediate eye injuries, sometimes without us even realizing it. Therefore, it is essential to use goggles with an appropriate protective filter, which allow the welder to clearly see the metal he is working on. These goggles also have side shields to prevent sparks from reaching the eyes.
Más que el precio, lo importante es elegir el filtro adecuado para la intensidad y tipo de soldadura que se realice. A mayor intensidad o duración de la soldadura, se requiere un nivel de oscuridad más alto, determinado por los valores DIN.
El DIN indica el grado de filtración de la lente y está regulado por la agencia DIN (Deutsches Institut für Normung). La escala varía de 1 a 15:

  • DIN 1: Cristal completamente transparente.
  • DIN 15: Cristal completamente opaco.

Each welding technique produces flames with different characteristics and specific emissions in the UV and IR spectra. Therefore, it is essential to select the lens that can withstand the intensity without compromising protection. If you are in doubt about which DIN is best suited to your job, our team will be happy to advise you.

  • For occasional work: Over glasses, which fit over your personal prescription glasses, are a practical and cost-effective option.
  • For extended, daily work: Investing in prescription welding glasses is the best choice. At Pegaso, we offer prescription glasses with overlay welding filters, which provide greater comfort and effectiveness during long workdays.
  1. Identifica el tipo de soldadura que realizarás.
  2. Evaluate the exposure time your eyes will be subjected to.
  3. Determine the DIN required for that activity.
  4. Decide whether you need prescription or neutral glasses.
  5. Choose from the different models available.

Welding involves mechanical, chemical and radiation risks. These threats can cause:

  • Burns to the cornea, retina or lens.
  • Irritations or conjunctivitis.
  • Serious damage such as severe burns or total loss of vision. Therefore, protective glasses are essential to avoid eye injuries.
It is a visual discomfort caused by excessive exposure to intense welding light, which can reduce the ability to distinguish objects and, depending on the exposure time, become disabling.
The level of darkness depends on the flow rate and intensity of the welding machine. Typically, filters between DIN 3 and DIN 7 are used, although the specific value may vary depending on the task.
