WEBVTT 00:05.269 --> 00:07.269 Doctor gives us a prescription . We 00:07.269 --> 00:09.380 keep a copy , doctor keeps a copy and 00:09.380 --> 00:11.547 then we give one to the patient and we 00:11.547 --> 00:13.658 use for fabrication . So I'm going to 00:13.658 --> 00:15.720 go ahead and give ourselves our copy 00:16.590 --> 00:18.923 once it checks out and it's been sorted , 00:18.923 --> 00:21.034 we take it right over here to get the 00:21.040 --> 00:23.079 actual prescription lenses . So 00:23.090 --> 00:25.090 whatever the doctor is prescribed , 00:25.090 --> 00:26.701 we'll go ahead and pull it . 00:28.940 --> 00:31.107 So now we have his lenses , let's grab 00:31.107 --> 00:33.329 our frame and then we're gonna bring it 00:33.329 --> 00:35.740 right over here to the lensometer . The 00:36.119 --> 00:38.380 lensometer is going to position the 00:38.389 --> 00:40.445 axis again based on the prescription 00:40.445 --> 00:43.130 the doctor has prescribed . So this one 00:43.139 --> 00:45.361 is going to be a 75 on the right lens . 00:45.470 --> 00:48.139 This is to compensate for a stigmatism . 00:48.150 --> 00:50.206 So the shape of everybody's eye is a 00:50.206 --> 00:52.261 little different . And so we have to 00:52.261 --> 00:54.483 refract the light at a certain point on 00:54.483 --> 00:56.372 the retina in order for us to see 00:56.372 --> 00:56.340 clearly . That's why we don't see 00:56.349 --> 00:58.127 clearly because it's doing that 00:58.127 --> 01:00.529 incorrectly . These three dots give us 01:00.540 --> 01:02.599 the position of that axis so that we 01:02.610 --> 01:04.830 can put it over on the blocker for 01:04.839 --> 01:07.559 decentration . So the decentration is 01:07.569 --> 01:09.902 just a little bit of math involved here . 01:09.902 --> 01:12.690 So everybody's P D which is pupil 01:12.739 --> 01:14.739 distance is a little different . So 01:14.739 --> 01:16.961 again , taking off the prescription and 01:16.961 --> 01:19.017 the reading that the doc took during 01:19.017 --> 01:20.850 their exam and then the frame is 01:20.850 --> 01:22.739 obviously a little different . So 01:22.739 --> 01:24.961 because everybody's head is a different 01:24.961 --> 01:27.072 shape and different size , we have to 01:27.072 --> 01:29.239 do the decentration to compensate . So 01:29.239 --> 01:31.461 the geometric center of the lens versus 01:31.461 --> 01:33.517 the optical center of the lens . And 01:33.517 --> 01:35.572 now this chuck is now at the correct 01:35.572 --> 01:37.572 position at the correct axis on the 01:37.572 --> 01:41.129 correct lens for the edger over 01:41.139 --> 01:43.309 here . So as he's hitting the template 01:43.319 --> 01:45.720 here for the specific frame , it 01:45.730 --> 01:48.040 matches the correct size and the shape 01:48.050 --> 01:50.161 of this frame . So it's a finale . So 01:50.161 --> 01:52.328 he uses the finale blank . He's got to 01:52.328 --> 01:55.010 position the right eye chucked on the 01:55.019 --> 01:57.250 horizon . Air pressure is going to hit 01:57.260 --> 01:59.316 that Chuck , make sure it's nice and 01:59.316 --> 02:01.371 tight and he's going to go ahead and 02:01.371 --> 02:03.538 position all of the bevel and all that 02:03.538 --> 02:05.704 good stuff when he cuts it . And after 02:05.704 --> 02:07.593 he finishes cutting it , after he 02:07.593 --> 02:09.593 finishes putting the bebble on , he 02:09.593 --> 02:09.279 needs to take it over to the bevel 02:09.289 --> 02:12.300 wheel so that this nice sharp edge 02:12.490 --> 02:14.657 doesn't cut anybody . So he's going to 02:14.657 --> 02:16.823 make that nice and smooth . He's going 02:16.823 --> 02:18.879 to buff it down on this little wheel 02:18.879 --> 02:21.101 over here . Once he finishes that , can 02:21.101 --> 02:23.429 you toss that ? We have a finished , 02:23.440 --> 02:25.551 almost finished product . So now that 02:25.551 --> 02:28.470 we have a pair of glasses with lenses 02:28.479 --> 02:31.220 at the correct prescription . We have 02:31.229 --> 02:34.009 to Q A it and make sure that what we 02:34.020 --> 02:35.853 made through all of that process 02:35.853 --> 02:38.529 matches what the doctor ordered and 02:38.539 --> 02:41.169 what the patient was prescribed . This 02:41.179 --> 02:43.346 is a good pair of glasses . It doesn't 02:43.346 --> 02:45.457 have any scratches or chips in it and 02:45.457 --> 02:48.119 it's ready to go and sorted for looks 02:48.130 --> 02:51.839 like . But so gets this one now that 02:51.850 --> 02:54.199 this is all set and done , that start 02:54.210 --> 02:56.350 to finish , took approximately 10 02:56.360 --> 02:58.471 minutes . On average . Sometimes they 02:58.471 --> 03:00.249 take a little longer if they're 03:00.249 --> 03:02.304 complicated or thick lenses , take a 03:02.304 --> 03:01.990 little longer to cut . If they're 03:02.000 --> 03:04.111 smaller lenses , sometimes they'll go 03:04.111 --> 03:06.333 all the way through in two minutes . So 03:06.333 --> 03:08.500 the average we like to say is about 10 03:08.500 --> 03:10.389 minutes . This was a good pair of 03:10.389 --> 03:12.333 glasses ready to go and that's our 03:12.333 --> 03:13.889 process to start to finish .
