TQM Blue Light Safe Glasses block all visible wavelengths of light except for blue, so if one wears them and can see in the screen making lab, then one has blue light contamination which will affect emulsions and films before and after stencil making, reducing the reliability of stencil production methods and ultimately printing quality.

CHARACTERISTICS

• Comfortable and durable glasses
• The one simple tool you need to ensure optimal light settings
• Easy to store in the screen making area
