Re: [Aus-soaring] New Rules: Start Heights
This is a loaded issue, with arguments on both sides. I think Matthew has it about right. Poorly considered rules can yield severely unbalanced results, which is not necessarily to everyone's benefit. Years ago at Kingaroy, with a strong South Westerly, a pilot with a motor glider volunteered to launch first, as a snifter. Conditions being unsoarable, he motored upwind into the lee of the Bunyas and caught the wave. An hour and a half later the field launched into barely soarable conditions and the start gate duly opened. Whilst the field struggled to stay aloft and to get around the course, the snifter simply glided downwind, around the first turnpoint and nearly to the second. The winning margin was spectacular. Half the onlookers thought this was heroic since the rules at the time did not actually preclude it, the other half felt it to be other than in the spirit of the contest. Take care with rules.

Re: [Aus-soaring] Contact lenses, laser surgery etc
G'day Bernie, Sounds to me like you have joined the presbyopes club-welcome aboard. It is the long-sightedness of "old age" and it happens to everyone, usually starting in the forties, even to those who've been short-sighted all their younger life. The degree of presbyopia often continues to develop [usually fairly slowly] until into one's sixties. I'm not an ophthalmologist, but I do work with several and none that I've spoken to would recommend laser surgery for presbyopia and although they acknowledge that laser surgery works for myopia none of them have had it done! I.E. those who need correction wear glasses. As for bi-focal contact lenses, are you sure that they don't mean 2 different lenses, so that you use one eye for close work and the other for distant work? Finally, if you can't focus on the TV when you look over the reading glasses it might mean you're a candidate for multi-focal glasses. As a long term user of the same I can assure you that although they take a little bit of getting used to, the pleasure of having the whole world in focus again is well worth the fairly minimal effort. Regards, Colin P.S. I still use some cheap but strong reading glasses for the really close-up work like removing splinters or undoing knots in fishing line From: aus-soaring-boun...@lists.internode.on.net [mailto:aus-soaring-boun...@lists.internode.on.net] On Behalf Of Bernie Baer Sent: Sunday, 18 August 2013 10:59 AM To: aus-soaring@lists.internode.on.net Subject: [Aus-soaring] Contact lenses, laser surgery etc For a year or so now I have been using bi-focal glasses for driving at night, and the same prescription in sunglasses for flying, fly fishing and driving on sunny days. On a recent fishing trip to a remote Pacific atoll I spoke to a guy who had had laser eye surgery to correct his long sightedness who was very happy with the results. On my return, I did some research and noted that the laser surgeons reccommend using contact lenses before having the surgery to check how you will respond to having 'monovision'. I then did some more reading on contact lenses and was happy to read that they are available in various bifocal configurations (see http://www.allaboutvision.com/over40/multifocalcls.htm ) I am now interested in perhaps getting contact lenses (cheaper than laser surgery) and then being able to choose from a much bigger (and potentially cheaper) range of regular sunglasses. Has anyone taken this route? I would be interested to hear your comments. Thanks, Bernie.

Re: [Aus-soaring] Contact lenses, laser surgery etc
Thanks Bernie, Interesting. I prefer not to undergo laser eye surgery. Those who have had it seem very happy with the results, but there is always a small risk of an adverse result that I prefer not to take. Can you let us know how you like the contact lenses?
