Nano Vista Clip-on eyeglasses are a type of eyewear designed specifically for children that feature a durable and sturdy frame made with nano materials. The unique feature of these glasses is that they have a clip-on mechanism that allows them to be easily attached and detached from a child's regular glasses. The clip-on lens can be used for specific activities such as reading, sports, computer use and more. They can also be easily removed when not in use and put back on as needed. They are marketed as indestructible, suitable for sports and other activities, and also as a cost-effective solution for children who need multiple prescriptions. T
