1. Due to transportation, distribution, and other reasons, a very small number of products may have uneven placement of mirror legs. This is not a product quality issue. Please contact customer service online in a timely manner for guidance on adjustment methods. 2. When wearing and taking off glasses, please hold the legs of the glasses with both hands and remove them from the front outwards. Wearing and taking off glasses with one hand can easily cause deformation and loosening. 3. When not in use, wrap the glasses with a lens wiping cloth, with the lenses facing up and placed in a dedicated glasses case to prevent scratches on the lenses and frames from hard objects. 4. If the frame or lens is contaminated with dust, sweat, or grease, please clean it with neutral detergent and warm water, and then dry it with a soft cloth. Do not contact glasses with cosmetics, perfume, alcohol and other articles containing chemical products to avoid corrosion and damage. 5. It is prohibited to stay in water for a long time, soak in water, or place it in a fixed location exposed to sunlight. It is also prohibited to place it on current or metal edges for a long time. 6. Please do not leave the photosensitive color changing mirror in direct sunlight for a long time, otherwise it will shorten the use time of the color changing effect. However, if the photosensitive color changing gradually becomes ineffective due to long-term wear, it will not change the UV protection effect. Please feel free to use it.
