Medical Forum / General / Vision / February 2007Most scratch resistant plastic / organic lenses, pls??
Hi All I've read the marketing on the manufactures websites, now I'd like to hear about your experiences, please. Thanks a lot. jbr Ride your 2 wheels, but in order to ride them yet another day! bbb Already told you to get plastic. You ride a bike, you need a lens that is impact resistant. Wear glass and they shatter, you go blind and can't ride your bike again. Your choice. Anti fogging and safe, versus fogging and going blind. Sort of a no-brainer in my opinion as an optometrist. dr grant So, are all plastic lenses, from all brands, with or without all coatings, equally resistant (or not) to scratch, or haven't you read my question properly, to start with? I can't see a sentence in your message where you reply to my question, this time. I'm planning to move to plastic; nevertheless, my glass lenses have fallen to stone floors dozens of times, I've been hit by a van while riding my bicycle, went rolling around on the floor, and my lenses never broke, and don't have a scratch. It doesn't come in the books that way, but books aren't always right. Regards, jbr >Already told you to get plastic. You ride a bike, you need a lens that >is impact resistant.

Some are better than others. Most multicoats are the hardest of all coatings. Check with your optical outlet and let them know. You want plastic, the hardest to scratch multicoat available with hydrophobic and lipophobic coatings. dr grant >Most lenses have scratch resistant coatings these days. Some are >better than others. Most multicoats are the hardest of all coatings. I'll bear that in mind. thank you. >Check with your optical outlet and let them know. You want plastic, >the hardest to scratch multicoat available with hydrophobic and >lipophobic coatings. From what I've been reading on the web, it sounds to me like your talking Zeiss... It just so happens I have a particular problem with Zeiss (and Essilor too): I just HATE the laser mark of the brand on the lens, that distracts me when I'm trying to concentrate on something visual, and sudendly there's a strange element in the way of my vision! (My previous lenses were Zeiss, and I had them for about... 10 years.) I like what I've been reading about in the Hoya website. Any problems with Hoya that you're aware of? Any other suggestions? Thank you, jbr Ride your 2 wheels, but in order to ride them yet another day! bbb ????? Singlevision lenses don't have markings, albeit they did do it at some manufacturers a while back. All multifocals have microengraving ~15mm to the side to locate the lens, but that is all. Hoya makes good lenses also. dr grant |
