General Purpose Safety Eyewear (Model Number or Brand Name)
In the industrial/general safety market, "207" is often just a model number or part of a supplier's internal product line name ("Yellow Line").
For a general-purpose safety goggle, the likely features are:
Lens: Clear, anti-scratch, anti-fog Polycarbonate lens.
Frame/Line: The "Yellow Line" might denote a specific series with a bright yellow frame or bright yellow accents on the temples/strap for high visibility in a workplace.
