Maria 029

These Preciosa glasses are another example of bifocals with almost plano lenses for long distance, bought by a lady who disliked the constant switching with readers - or worse, the constant searching where her readers were. No such problem with bifocals. Simply keep them on your nose.... Here Maria is standing at the front door of Kungshuset, checking her looks through the reading parts of the glasses. The Preciosa pair was probably made in the late 1970's. The first progressive lenses appeared on the market in the late 1960's but it took another decade before the new technology was out of its early stage and prices lowered to those of bifocals. Aside from comfort and cost, some people just can't get used to the cosmetic discrete progressive lenses. Also, the reading segment in bifocals is well defined, giving the user a better view at reading distance.
