| 1326384 | 2013-02-04 06:08:00 | My wife bought a pair of glasses like the one in your pix. Never again. They kept falling to pieces. The next one she got had metal rims. No problems with those.. Yeah, the rimless style shown is held together by a tiny bolt through a hole drilled into the lens, making the lens (and bolt and hole) all integral to the entire structure. If they get any rough treatment, or get handled a lot (on/off/on/off) they'll either break or go floppy in no time. But they're also nice and light to wear. As for the pic - looks like a rough as guts job of edging (grinding/cutting) across the top of the lens... or is that a trick of the light? Looks to me like the whole experience has been sub par from start to finish... but if they're hobby specs (ie pre-made cheapies), well, you get what you pay for. Can't beat the price, but sometimes quality gets lost along the way. |

| 1326385 | 2013-02-04 06:11:00 | Thanks Paul some good information there. I have just got reading glasses for the first time, well at Christmas. I use them with my desktop, laptop and books. However they are useless for watching TV which from your comments is to be expected | gary67 (56) | ||

However they are useless for watching TV which from your comments is to be expected Yup. You'd need either a Progressive lens type, or (if your distance vision is good) a half size (Look Over The Lens) style much like BBCMicro has had his mod'ed to, which is a really good, practical solution if (and only if) your TV is fine without any correction. If you benefit from lenses for driving, then you'd also benefit from the same lenses for TV, and vice-versa. As a side issue, it amazes me how so many people will readily wear specs to make the TV a nicer experience, but never think to use them for their driving experience. Guess it also reflects where our priorities sit... a clear TV being more important to many than a clear view of the road. Sounds crazy, but I strike this every day at work... "yes, I wear them for TV. No, I drive without them". Sheesh! Happy, safe driving folks. |

| 1326387 | 2013-02-04 06:33:00 | I have 2 pair of glasses. Bifocals for reading and using the computer and another pair for distance, anything over about 1m. :) |

| 1326388 | 2013-02-04 06:36:00 | 'Back in the day' when I was young and carefree, and my eye muscles could accommodate, and due to having one short sighted eye and one long sighted I could focus and see from about 70mm up to infinity without glasses. Even today I can read and also watch tele without glasses using different eyes, however I have one pair for close work that go down to about 150mm, another pair for desktop computer screen, and another pair for driving. For really close up fine work I wear a magnifying visor over my close up glasses and so get equal focus with both eyes. So-called hobby glasses are of no use with my unequal eyes. |

| 1326390 | 2013-02-04 07:55:00 | Driving must be difficult with one short sighted & one long sighted Not with glasses, which mainly provides correction for my short sighted eye, and a very small correction for the long sighted eye. If I dont wear glasses, steroscopic vision, judging near distance is not good, 'frinstance trying to find the clothes line when hanging out washing. |

| 1326391 | 2013-02-04 08:03:00 | I have eyes like Terry. Mine went like that after having cataracts removed in both eyes about 5 years apart. What happens if I don't wear my distance glasses the good eye fools the brain into thinking that you have both good eyes and everything looks normal, but I wear my distance glasses as it makes things more sharper. :) |

| 1326392 | 2013-02-04 08:15:00 | Likewise, I've had one long, one short for 30 years. The key to it working well is to be just a tiny bit longsighted, and moderately shortsighted. And with sod all astigmatism. In my case however my eyes don't point straight, with the left eye aiming lower than the right, which the old brain does not tolerate very well, so in my case it's best to wear specs as much as possible. The example Terry points out is a good one, especially for folk who've been used to being a bit shortsighted for much of their life. Modern cataract surgery can do a fantastic job of correcting most typical eyes, so there's some sense to actually choosing to have one eye left shortsighted, and reducing your dependance on glasses. Admittedly, glasses will balance the eyes out better and give a more comfortable solution, but the 'monovision' way of correcting things works well, especially with some adaptation time, and is great for folk who are failry active / too rough to care for a pari of specs. Having said all that, most people choose to have the surgeon set them bang-on for distance, and just needing hobby specs or simple readers for near work. Either strategy is fine. |
