Within the last 3 years, my wife and I both had new glasses prepared from new prescriptions. In both cases, the lenses have been very prone to develop smudges that result in areas of blur, as well as excessive amounts of scratches. My wife has already had hers replaced, and I'm wearing my previous prescription glasses, until I can get around to replacing the pair I'm supposed to be wearing. We've both worn glasses for decades. I've never encountered such rapid deterioration before. Did we get suckered into some coating that is susceptible to easy damage, or have the manufacturers developed a way of making glass less durable, so we have to buy more, or have we just been unlucky?.
