I had put on my glasses for the following situations: - Could the Mechanics, though once injected material through the area and damage the glasses - On the beach, if you do not scratch the glasses by own grains of sand or even lose possibly want - In the bathtub - As a convenient temporary solution for wherever you go (Auto, Sport, Shopping) For this thought delivered by me Applications I find the spectacle, especially at the price, just awesome! It is extremely light, yet holds a lot and if it does once the glasses being damaged during extreme conditions, is not a lot of money broken! To read on the sofa or in bed, I take my glasses from the optician and for this price you can not expect quality as the retailer. But as I said: perfect for the imaginary of my areas of application, as I so do not want to spend hours reading a book, but just need support in crafts or shopping! So who needs a spectacle, for their own use, expensive is too bad, makes this solution certainly no mistake!
