Optimization of visual modalities using lenses .
Previous Itarin discussions involved training the normal eye's retinal neural networks to compensate for eye-lens and corneal defects using Itarin v1-v11 . This was useful for about 10 years , but now external lenses have to be used .
I was handed a pair of multi-focals (after paying a small fortune) , with the blithe assurance that I would adapt to it within about two weeks .
1.This adaptation is by the retina-mind complex .
2.This adaptation is sub-optimal , by definition . A hit-or-miss affair .
What is needed is a theory and a training program .
See previous Itarin documentation . But we expand it to include different modalities of retina neural-network processing . One for each set of lenses .
There has been hints of it . Training processed faster and better by alternating glasses and unaided vision .
1.Are the retinal neurons complex enough to handle multiple modalities ?
Yes . See work done on single-neuron recognition of faces .
2.Automatic switching .
Portions of the network would change between modalities with very little training .
This is inherent in the nature of neural networks .
This surfaces as "bleedthrough" . A gestalt effect . All modalities get better .
3.How many modalities are minimum necessary sufficient ?
From previous dimensional systems work , four .
Unaided vision , Multifocal lenses usually includes 2 new focals . An extra pair of cheap reading glasses makes four .
Initially , the training process would require the formation of extra connections and maybe neurons in the retina-brain . Brain food like essential fatty acids (cod liver oil , flaxseed oil) and perhaps HGH promoters will help .
Long-term neural potentiation thresholds (about 5 minutes) have to reached and slightly exceeded for optimal effect . The boring bit .
Once a day for about a week .
Then once a month.
Research is needed .
6.Subjective experiences :
Even a short training session gives a feeling of relaxation and stress relief . This is because of unconscious squinting and facial muscle tensing relaxing as vision improves .
Natural vision improves because of "bleedthrough" effect . The training has to be carried through , as this short-term relief will probably lead to relapse of training . A common enough problem . Taper off and have a refresher training session about once a month .
The Training Systems .
1.Each session has to be about 5 minutes per set of glasses (multifocal , reading) and unaided vision (ie normal lenses) .
Fifteen minutes in all . Boring .
2. Itarin v1 to v11 can be used . Some quick results .
3.Itarin v12 .
Populate the screen of a spreadsheet (like Excel) from a master cell (like "B") .
"B" gives the most bang for a buck in terms of visual training (curve , line, corner)
Squash the Column Width ("Format-Column-Autofit Selection") to minimum size .
The Trick : The Modified Owl Maneuvre (MOM) .
1.Look at the centre . Move the center of your gaze in an infinity figure . ("8" on it's side)
2.Do the same with the "8" upright .
3. Do the same with the "8" tilted 45 degrees to the right .
4. Do the same with the "8" tilted 45 degrees to the left .
5.Repeat for five minutes for all 4 (1.25 mins for each rotation)
6.Then repeat for each set of lenses . Use a kitchen timer .
7.That’s it .
You will find items (3 and 4) quite difficult initially .
Why the modified Owl Maneuvre ?
The owl only needs to calibrate two eyes in two dimensions (+) , ie up and down , right and left , as it has nearly no visual defects like astigmatism . An astigmatic owl is a dead owl .
With visual defects , an entity has to have loops around the ends of the crucifix figure. Hence the "8" rotated around at 45 degree angles .
The end result :
You should end up with a unaided visual system suitable for most tasks . The lenses would still be needed for training or tasks at the extremes .
We cannot dispense with the lenses , but can expand the useful boundaries of unaided vision .
Here's looking at you , kid .
