Thank you for viewing! This item is unopened. [3-way Specification & Children's Hay Fever/Dust/Protective Glasses] These are safety-designed "hay fever glasses" specially made for children. Pollen cut rate: 99% *Size (with dry eye symptom relief function): For children aged 3-14 ★According to our own verification, the pollen blocking rate is 99% or more. ★The side guard part is removable and has a 3-way specification. Way 1: Guard glasses have a high degree of contact with the eyes, making it difficult for pollen to pass through and protecting the eyes firmly. Way 2: Apart from the hay fever season, the shield can be removed and replaced with nose pads, allowing you to use them as regular glasses (PC glasses). Way 3: Can be used as dry eye relief glasses. By attaching a water retention pack (pair) to the water retention sheet and injecting water, the humidity inside the frame is maintained, preventing dry eyes. Compared to the old model, the hood is deeper, preventing pollen and dust from entering, and is widely applicable in places with a lot of dust, when going out on windy days, etc. [High-performance anti-fog coating on both sides of the lens & 35% blue light cut] ★Because high-performance anti-fog coating is applied to both sides of the PC transparent lens, a comfortable view can be secured all day long. It is difficult to fog up even after long hours of use. The anti-fog effect is very good. ★The lenses use UV cut & 35% blue light cut lenses, and the functionality is also enhanced. In addition to blocking pollen and dust, as a measure against "smartphones and tablets," it effectively blocks harmful blue light from devices such as tablets and smartphones, and can also effectively prevent blue light and ultraviolet rays. ★With an elastic glasses strap to prevent glasses from slipping!
