The Polaroid PLD 2166/S sunglasses for adults feature a black frame with polarizing lenses designed to reduce glare and enhance visual clarity. This model utilizes Polaroid's advanced polarization technology that effectively blocks horizontally reflected light, making it suitable for various outdoor activities where glare reduction is beneficial. The frame construction provides durability with a focus on reliable daily wear, while the polarizing lenses offer improved contrast and color perception compared to non-polarized alternatives. Measuring approximately 140 mm in width, 50 mm in lens height, and 145 mm in temple length, these sunglasses are designed for adult facial proportions. The polarizing filter is integrated into the lens material, eliminating the need for additional attachments. This eyewear is intended for general outdoor use where glare reduction from surfaces like water, snow, or roads can improve visual comfort. The black frame color offers a versatile appearance that coordinates with various attire. As with all polarizing sunglasses, optimal glare reduction occurs when the light source is at specific angles relative to the lens orientation. The PLD 2166/S represents Polaroid's continued development in polarization technology for everyday eyewear applications.
