Your customers are going to love the simplicity of these blue light-blocking classic glasses and how versatile they are in terms of complementing any choice of clothing. In addition to their aesthetic appeal though, these glasses perform an important function -- limiting the amount of blue light reaching the eyes from digital screens, which is a big problem these days. Comfortable to wear throughout the day, these understated clear glasses will be a hit with both your male and female customers. Sold here in bulk units by the dozen.
