Ero abituata alle lenti d'ingrandimento classiche in vetro , spesse e pesanti ! Mi sono imbattuta in questo tipo di lenti molto sottili e leggere e devo dire che fanno egregiamente il loro dovere . Naturalmente sono un po' piu' delicate rispetto a quelle in vetro ma con piccoli accorgimenti e' facile prolungarne la durata . Vanno mantenute nella loro custodia per impedire graffi e che si sporchino . Infatti i tratti in rilievo che permettono l'ingrandimento tendono a sporcarsi ma basta pulirli delicatamente con un batuffolo umido di ovatta che le lenti tornano ad ingrandire senza rifrazioni delle immagini desiderate. Le consiglio vivamente

I rate this basic flexible fresnel magnifier as a good value. I would buy this product again. Pros: - The magnifying power seems to be 2 to 2.5x. It is essentially a little zoom lens in which your hand does the zooming. You move the lens up and down to adjust the magnification. - The fresnel plastic material is very light and easy to hold when reading. - The magnifier is sharp edge-to-edge unlike the cheap plastic round magnifying glasses, which are sharp at the center but blurred at the edges. - The magnifier is flexible and can take some bending, making it okay to carry around in purse, pocket or belt pack. - The blue plastic case provides protection from scratching and losing it. The lens itself is clear so it is easy to misplace. - I treat it with care. I had no problems with scratches in ordinary use. - The lenses are inexpensive and come four to a pack, giving extras to carry around with you or to leave at home. Cons: - This is a low power magnifier. I use this as a regular carry-around to get an extra boost when reading newspapers or magazines. If you have a specialized use like reading prescription labels or legal fine print, you may want to buy a 5x power or stronger magnifying glass made from real optical glass. Or if a stamp collector, a loupe. -- I bought this magnifier myself with my own money for my own personal use. All opinions are my own. I am not affiliated with the seller. I did not get this product free in exchange for a review.

on retrouve la meme "technologie" qui habille les caisses de super-marché ! c'est le même principe de cercles concentriques, je m'y connais pas assez en optique pour élaborer... mais du coup on a une loupe fine comme une feuille de papier (enfin un peu plus, hein...) à un prix mini et au format tellement utile de la carte de crédit. ça tient dans le porte-feuille, ça se fait oublier, et c'est super utile quand le besoin s'en fait sentir. un gadget top et pas cher !!!

Clear crisp magnification. Handy little item to carry in your wallet or purse.
