All-clear, ultra-lightweight, screw-free, and easy to care for. Air-like care glasses. 【Overview】 inPlain is a pair of glasses with a frame that weighs only 4g!! These are eye-care glasses that were a big hit on a Korean crowdfunding platform. They are ultra-lightweight with a simple structure that connects smoothly in a single line without any screws. You can enjoy your daily life without even feeling like you're wearing them. They are made from biomass (plant-derived materials) with the environment in mind, making them eyewear that is gentle on both people and nature. 【UV & Blue Light Cut with Just One Pair】 Your eyes are overworked and exposed to stress all day long from smartphones, computers, and UV rays. You can coordinate your style fashionably while cutting all those external light rays. The lenses cut 99% of UV rays that affect your eyes and skin. In addition, the blue light cut results are 99% in the 380-410mm range, which is the most harmful HEV range for the eyes, and 64% in the 410-420mm range. The cut rate has been tested by a Korean inspection agency. 【Comfortable Fit & Easy Care】 The screw-free structure means it won't loosen and is easy to care for, and there's no need to tighten it. The integrated fit and joint structure, with silicone nose pads, only provide a light sense of adhesion during wear. The eye frame and temples (glasses legs) are connected with a single joint that moves without screws and a custom structure. Therefore, there is no need to worry about screws rusting or loosening, and it is more flexible to external impacts, so you can maintain the quality of the glasses firmly without deformation for a long time. 【High Quality & Eco-Friendly】 ・ Beta-titanium (β-TITANIUM) is used for the temples (glasses legs). Titanium is biocompatible, safe for the human body, and is a material used in real life, such as watches and implants. It has a high strength-to-weight ratio and is used in high-end glasses, and the manufacturing process is difficult because it requires specialized technology, and the material itself is expensive, so the price of the glasses is also high. Among titanium, beta-titanium is stronger than regular titanium, and has high elasticity and resilience, and it can be restored without difficulty even if pulled or stretched, and it bends to fit your face for a comfortable fit. Also, it is a material that hardly deforms or changes due to salt (sweat). 【Stylish Design】 There are three frame shapes available: "Oval," "Round," and "Square." Please check the shapes in the images and choose your favorite model.
