| 1326414 | 2013-02-07 09:52:00 | If you're too stupid for words, then you should avoid contacts (sorry, but we do get cases where some folk are their own greatest hazard, due to their total stupidity) If you're poor or tight fisted you should not try contacts (tight folks persist in wearing lenses that have degraded into a terrible state, and injure themselves in the process - kind of gels with the 'to stupid for words' group, even though these folk can be bright)Many people don't realise they can cause permanent eye damage or loss with less than hygienic eye/case care or unsafe practices. Get yourself an eye ulcer with a nasty bug/fungus/parasite and you have a big problem. |

| 1326415 | 2013-02-07 10:11:00 | For Clod: I really don't follow the prices, partly because that's done by other staff, and partly because there's just so many variables that go into the answer. The brutal answer is that you can get Progressives that are horrible for sod all money, and Progressives that are beautiful for lots of money. Where you choose to draw that line depends on your own finances, your work circumstances, your visual needs, and your lifestyle/personality. If your work carries a high chance of damaging a lens, then you might want to consider a cheaper grade of lens, or a higher grade with some insurance cover (if available where you go... I touched on the OPSM Eyewear Protection Programme in an earlier reply - I don't need it for myself, coz I treat my specs with great care, but I'd add the cover to my Brothers glasses immediately, coz he's been an active DIY sort, who got a big scratch on his last pair shortly after they were new - frustrating for all concerned!) Using a frame you currently own can save a bundle, but don't put an expensive lens into a frame that's due to fall apart in 6 months time. With the auto tint (Transitions) on a Progressive lens, I'd really expect you to pay an absolute minimum of $350 for the pair (plus frame), up to $1000 for the top of the range. Just bear in mind that a top of the range lens should also be given top of the range care. If you wipe with a tissue, or place them face down (lens versus table surface) then you're probably not wise to buy to a premium lens. I won't go into slagging off other cmopanies product by name, but I will say that many from the widely promoted discounting chain stores have a progressive lens that looks disgusting to an experienced eye. When examined on a vertometer (lens meter) the cheapie progressives have terrible channel width, and terrible off-axis distortions, to the point where it's almost impossible to determine their power. So... you get what you pay for, but don't pay for more than you need. Sod all help probably. I hate paying for them myself, so I can sympathise, but given that your eyes are your primary 'input' for almost everything you do, it does make good sense to give them the best that you can happily afford. Or on the other hand... if you're finding yourself bothered by awkward vision in cheapie progressives, would you find it sufficiently comforting to remind yourself you saved about $2.00 per day by having the cheaper product? If you preference is to save $2.00 per day, go with cheapies. If you think having a sweet visual experience is worth an extra $2.00 per day, then raise your sights to the premium lenses. If you can make them last 3 years or longer, then the added cost of the premium lens has cost you less than $0.70 per day... think on that next time you have a coffee for $7.00 |

| 1326416 | 2013-02-07 10:22:00 | [QUOTE=DeSade;1145388]Yes They are called Toric lens. I use them myself for a bad astigmatism. Thanks for the link DeSade ... I assume these aren't off the pharmacy shelf ones. Any chance you could give me an idea of price (via PM if you don't want to post) and how / where you get them from. Just to butt in... If that's a contact lens you're thinking of, then be aware that it must fit correctly in order to be healthy, plus you should be tutored in getting it in, out, cleaned and disinfected. Please don't be tempted to buy online until you've had a correct contact lens prescription determined. The numbers off a spectacle prescription do NOT guarantee a safe fitting contact lens, and your comfort in a lens also does not determine a safe lens. A lens that is too tight on the eye usually feels great. It will also encourage blood vessels to invade your cornea, and for material to stagnate between the lens and the eye, resulting in infections, ulcers, and other unpleasant drama. Monthly toric contact lenses are usually around $65 per pack of 3 if memory serves, give or take, depending on the brand. Don't ever wear a cheapie contact lens while you sleep. Oh, and the current generations of coloured contact lenses belong in hell. They're trash. Don't go there. |

| 1326417 | 2013-02-07 10:31:00 | Many people don't realise they can cause permanent eye damage or loss with less than hygienic eye/case care or unsafe practices. Get yourself an eye ulcer with a nasty bug/fungus/parasite and you have a big problem. The extreme end of that being pseudomonas aeruginosa (if I've spelt it correctly), and acanthamoeba infections. PA lives on the skin, and in soil. Acanth... loves warm wet environs and hot springs. Infections with either can be absolutely and totally destructive of corneal tissue (ie permanently blinding). In the case of acanthamoeba there's typically about 9 months of sever ocular pain while they try (with limited success) to save the eye. It's a really tough bug to kill, and contact lens wear increases the odds of getting these nasties. While cases are rare, they do happen in NZ every year. Usually to people who have broken multiple rules of lens care and hygeine. Cold sore virus / chicken pox / herpes can be a close second in terms of agony and destructiveness if it gets into the eye. |

| 1326420 | 2013-02-07 20:06:00 | Glaucoma is in my family history so even I have only just started to need glasses I have had regular eye checks for years. Also thanks for all the info Paul very insightful | gary67 (56) | ||
| 1326421 | 2013-02-07 21:05:00 | Thanks for the info Paul. I assume that another visit to the optician is required to get fitted up with them ?? Only want them for shooting so would only be used about 4 or 5 days a month ... happy to wear glasses at other times but it's bloody hard to see the target when it's raining or the lenses of my glasses fog up ... even if it is a damn good excuse for not shooting straight ... :D |

| 1326422 | 2013-02-08 06:36:00 | Thanks for the info Paul . I assume that another visit to the optician is required to get fitted up with them ?? Only want them for shooting so would only be used about 4 or 5 days a month . . . happy to wear glasses at other times but it's bloody hard to see the target when it's raining or the lenses of my glasses fog up . . . even if it is a damn good excuse for not shooting straight . . . :D Yeah, maybe a couple of visits . If your power allows it I'd suggest 1 day disposables, so that you bin them after each days use . If you had a monthly lens, getting worn 5 x per month, you'd end up unsure of how much use they'd had after a couple of months . If it's solely for shooting, then there's the dilemma of lens rotation . If you're cocking your head to an angle as you snuggle up to a rifle, then the lens may need to be designed for a different axis to counter the head tilt and eyelid interaction . Likewise, if you're lying prone to shoot the position causes the upper lid to exert more influence on the lens, and may also cause it to rotate off axis . If you're standing using a shotgun or pistol this is unlikely to be relevant . You may have already said what you're shooting, I don't recall, and my 'net is capped to a crawl at the moment, so I'm not going trolling to find the post . I recall someone recently using a laser to sight, but can't recall if that discussion was online or at work . Looking up into the sky will often encourage a contact to drift off axis, giving some blur . The bigger the cylinder power, then worse the effect . |
