leohong Posted August 29, 2014 Share #1 Posted August 29, 2014 Advertisement (gone after registration) I am 63 and start to feel the pain when trying to focus. I have tried 1.25x and waiting for the new orange eyepiece from England to arrive. My eyes's short sightness is around -1.75. Just curios if any has LASIK and find it helpful. Thanks very much in advance. Leo Link to post Share on other sites More sharing options...

kdriceman Posted August 29, 2014 Share #2 Posted August 29, 2014 I had LASIK surgery 10 years ago and have had 20/20 vision since with no problems whatsoever. I am, however, beginning to have the age-related reading issues. My long distance vision is still 20/20 but my ability to read comfortably without reading glasses is waning. I am still able to focus a rangefinder with no problems. Link to post Share on other sites More sharing options...
bocaburger Posted August 30, 2014 Share #3 Posted August 30, 2014 I decided against Lasik because to correct for both nearsightness and age-related lack of close-distance accomodation they correct one eye for each, and the brain is supposed to adjust. I've worn glasses since 5th grade and see just fine with my glasses for everything including focusing a camera, rangefinder or SLR. I'm just chicken to surgically mess with my vision.

Carduelis Posted August 31, 2014 Share #4 Posted August 31, 2014 I had Lasik treatment three years ago, after wearing mainly contact lenses for 33 years. My short-sightedness prescription was about -9 and -7 in my left and right eyes respectively with -10 dioptre being the boundary with the Lasik treatment. To allow for close-distance accommodation, they set my left eye at -0.5 dioptre whilst fully correcting my right eye. I am very pleased with the results of the Lasik treatment with my eyesight being noticeably sharper than it was when wearing contact lenses. The other surprising difference is that I am seeing the world more vividly than before. The above treatment has also allowed me to have close and distance vision and so far I have not required glasses. I use my right eye to focus the camera which is easier now. I think it is great to wake up on a morning with good eyesight and not to have to worry about contact lenses and wetting solutions particularly whilst swimming and on long haul air flights.

blueuser Posted August 31, 2014 Share #5 Posted August 31, 2014 I had a LASIK threatment a couple of years ago. My dominating left eye is corrected for far sight and my right eye is corrected for closer sight so I can avoid glasses for reading (I'm 52 years). I am working as a video photographer in a national broadcast corporation and spending a lot of my spare time with still photography using dslr and my newly purchased M 240. That was one of my best decisions, because getting rid of my glasses gave me so much freedom. The only negative side effect is that my eyes get a little bit more irritated in dry and dusty enviroments. Link to post Share on other sites More sharing options...
Jennifer Posted August 31, 2014 Share #6 Posted August 31, 2014 I had LASIK surgery 10 years ago and have had 20/20 vision since with no problems whatsoever. I am, however, beginning to have the age-related reading issues. My long distance vision is still 20/20 but my ability to read comfortably without reading glasses is waning. I am still able to focus a rangefinder with no problems. I'm in exactly the same position. I had LASIK surgery in 2008. Given I was +3 long sighted they corrected one eye for long vision whilst giving me reading vision in the other. This worked well until earlier this year when my reading vision started deteriorating so that now I'm back to using reading glasses . My long vision, however, remains good and doesn't require correcting ..... yet. Given I always use my left eye, the one they only corrected for long vision, to rangefinder focus, I find it necessary to use a 0.5 dioptre adjustment to give me any hope of accuracy.

jonoslack Posted August 31, 2014 Share #7 Posted August 31, 2014 Advertisement (gone after registration) No, I haven't - because I'm just a long sighted old fool, and they can't correct it very well. However, I do have a tale to tell. I'm about +2.75 for reading and 1.75 for distance - I used varifocals for several years, but they're rubbish for both using the rangefinder and using a computer screen , I also tried using dioptres on the camera - but the dimming of the light made it even worse. . . . . so, about ten years ago my optician suggested using different contact lenses for each eye - and I've never looked back: I have a +2.75 in my left eye which is fine for reading (even my iphone) and a +1.75 in my right eye which is great for focusing the rangefinder. It has the added advantage that as your eyes change with age, you can experiment easily with different prescriptions. Incidentally, no chemicals or pots - I just use disposable contacts, put them in at 6am and fish them out when I go to bed. I have a friend who just uses one contact lens in one eye for reading. You people who have had Lasik and who are now suffering from aging might easily like to try a lens in your focusing eye much much MUCH better than a dioptre on the camera.

Seven years ago I had a detached retina in my right eye. After the surgery I was mono vision whether I liked it or not. It's the way I ended up. Having worn glasses since I was 14, they were always on my driver license. After the surgery my vision changed and I passed the driver eye test without glasses and they were removed from my license as a condition for driving. My left eye was perfect 20/20 without glasses. I switched to my left eye for rangefinder focusing. All was right with the world. Today I am in panic mode. Last Friday a blood vessel broke in the retina in my left eye. The doctor could not detect a tear or detachment in my retina. He is a nerve specialist and I am seeing a retina specialist 8 September to verify. My right eye has settled down over the years and I have reverted to using it for the rangefinder this morning and all seems okay. I am taking my M-240 with me to the retina guy and show him my dilemma. HOPEFULLY all will work out or else my rangefinder days are numbered and I will have to revert to the dreaded autofocus and use my ears to focus with the beep. Welcome, dear visitor!

bocaburger Posted August 31, 2014 Share #9 Posted August 31, 2014 I tried getting contact lenses years ago. Optometrist and 3 opticians swore they never saw anyone with as strong a blink reflex as mine. Literally impossible to put a contact lens in my eye unless I would be under general anesthesia.

Optometrist and 3 opticians swore they never saw anyone with as strong a blink reflex as mine. Literally impossible to put a contact lens in my eye unless I would be under general anesthesia. I used to be that way until the surgery and the preparation and aftercare but I'm cured of that now. Your eye gets touched A LOT in that process. Not only that, when I went to the ER doctor Friday the new and improved eyeball pressure sensor is a handheld device now instead of the air jet and they put it right on the eye. It was fun.

Thanks very much in advance. Leo No. If you have the correct specs and use the camera with them on you should be able to focus perfectly......... if you focus without you will need the correct dioptre corrected eyepiece. Magnification won't help ..... it will just make the out of focus image a bit larger., not sharper. Lasik may correct your -1.75 ...... but then you will need reading specs all the time ...... instead of taking your current specs off instead to read etc. As you age the lenses in your eyes lose their elasticity and the range over which you can focus reduces quite dramatically ....... which is why most people start needing reading specs in their 50's. Lens discolouration also acts like a brown filter ...... and cataract development can reduce sharpness insidiously (only correctable by surgery) .... and if you are very unlucky retinal ageing can reduce your acuity even further. Get things checked by a reputable optician before spending unnecessary cash ..... Link to post Share on other sites More sharing options...
Bill W Posted August 31, 2014 Share #12 Posted August 31, 2014 I had corrective laser surgery in 1997. This was before Lasik. I remember it was not pleasant and it took weeks for my eyes to settle down. When they did, I was very pleased. In 2000 I was given a free tuneup on my right eye by the same doctor as I needed some slight correction still. I am still very pleased. I just turned 65 and only use 1.25 reading glasses when I am sitting at the computer like I am now or reading the newspaper. It was so nice to be able to focus a camera and not need glasses. I wore bifocals before. Link to post Share on other sites More sharing options...

Optometrist and 3 opticians swore they never saw anyone with as strong a blink reflex as mine. Literally impossible to put a contact lens in my eye unless I would be under general anesthesia. I have the same reflex. My eyes close whenever the doctor gets close but I have no idea whether they are open or closed and can't figure out how to make them open. I had to change doctors because he would get so angry; new one is more relaxed, same reflex though. Link to post Share on other sites More sharing options...

wlaidlaw Posted September 1, 2014 Share #18 Posted September 1, 2014 I have the same reflex. My eyes close whenever the doctor gets close but I have no idea whether they are open or closed and can't figure out how to make them open. I had to change doctors because he would get so angry; new one is more relaxed, same reflex though. I have both a strong blink reflex and very dry eyes. I have tried contacts three times and not only find them very difficult to get in but they quickly become very uncomfortable. Determined not to give up, the last time, with the “new” gas permeable lenses, I stupidly persisted until I ended up with an ulcer on my cornea, which was very uncomfortable. I too wear vari-focals and they are not great for RF focusing. I have a +0.5 diopter in the RF which I find helps. I now use the EVF a lot on the M240, which I find much easier to use without lifting my glasses up each time (I have the large eye cup on it). However I do wish Leica had upgraded to the VF-4, because it is a huge step forward, with a 50% bigger and brighter screen. Strangely my old M4 seems much easier to use the RF than my more modern M’s. I have one of Dirk Rosler’s variable diopter 1.15X eyepieces on that.

wlaidlaw Posted September 1, 2014 Share #19 Posted September 1, 2014 I meant to add that my brother was very short sighted since a young child and had worn contacts for 40+ years. He had LASIK a few years ago, after he added some more modern “slicks and wings” cars to his historic racing collection. He found that the G loads and bouncing from the very stiff suspension could displace his contacts during a race, which was obviously very undesirable. He is delighted with LASIK but of course, now has to use reading glasses. Wilson Link to post Share on other sites More sharing options...
jdlaing Posted September 8, 2014 Share #20 Posted September 8, 2014 Sorry to hear this, hope it works out for you. So much for wishful thinking. The Retina was torn and I had the laser surgery this morning. They've made some improvements in seven years. I took my camera with me and explained all this to the doctor. He tried a few diopters and we settled on a 2.0 so I can now revert back to my right eye. Upside: no more nose prints on the LCD. Here's hoping the laser worked and the retina don't detach like last time. Link to post Share on other sites More sharing options...
