Why You Need to Wear Glasses When Glassblowing

Glassblowing is a mesmerizing art but comes with hazards, particularly to your eyes. The intense heat and light from the furnace emit harmful ultraviolet (UV) and infrared (IR) radiation, which can cause serious eye problems over time. This is why wearing protective glasses is essential for anyone involved in glassblowing.

The Dangers of UV and IR Radiation

When gathering glass from the furnace, your eyes are exposed to UV and IR radiation. Prolonged exposure to these types of radiation can lead to a range of eye issues, including:

Photokeratitis: A painful condition similar to sunburn but affecting the cornea.

Cataracts: Clouding of the eye’s lens, which can lead to blindness if untreated.

Macular Degeneration: Damage to the retina, leading to loss of central vision.

Retinal Burns: Permanent damage to the retina caused by intense IR radiation.
