FMP eyes

As a photographer my eyes are very important and I am very aware of looking a lot of the time and I wrote and told about them before because I have a genetic eye abnormality, fixation disparity, and I use my left eye instead of the right taking images. (right handed).

Needing new glasses, I couldn't see sharp any longer I visited the optometrist a couple of times. The cilinders turned over 30 degrees which is strange and the prisms changed as well. With the new glasses (progressive vision, with prisms and cylinders) I saw trapezes instead of rectangles. Far away the world moved and kept moving. I couldn't drive by car or read. The factory indicated that they were new lenses that were specially made, with fewer lens errors. But 1 out of the 10.000 (or less) people could not get used to it but just wear theme for two weeks and I would be used to them: NOT.

The glasses I had for 3 weeks

Without glasses I see everything double because that is what fixation disparity means to me. You can compare it with chromatic aberration aberration for lenses only without color. Both eyes just do not work together, causing an image to become blurred and a moving world with every movement of my head or eyes. Now 4 month further I have finally new glasses that work and my world stopped moving.

My daughter was measured at the same time and her prisms had deteriorated quite a bit. This could be because she spent a lot more time at the computer due to corona and home education, so it was advised to come back about three months later for another measurement, this weekend. It turned out that her prisms deteriorated much further.

A mystery until we talked about the insurance policy chosen because of the physiotherapy offer my daughter needs because of her hyper-mobility. This also turned out to be the cause of the deterioration of the eyes. Eyes largely work on muscles and if they are hypermobile, the same can apply to the eyes. We now have a cause but not a sollution. Fyshiotherapy for the eyes is not yet possible.

Left or right eye

Before I posted a blog on using the left or right eyes taking images wondering if the images people make are different using another eye. This because of the idea of the different working of right and left halves of the brain. As you can read in the answer I got mailing a brain institute with this question:

Last year I changed departments within the school where I teach. I now teach students studying audio visual design. In practical terms, this means that, in addition to an introduction to photography, I also give light, sound and camera lessons. The camera's we use are the Sony Z-150 and the RED raven camera. The RED Raven camera has a modulair system and looks as the Hasselblad in old days and we have it with a touchscreen and a viewfinder.

Having some students in the class also using the left eye we saw that there was a problem with film camera's; they are all build for people who use their right eye. One of my colleagues has one older camera that can be mirrored and used with the left eye but the answer all my, working as cameraman colleagues, gave was; "start training the other eye or choose another profession."

For me teaching and not filming myself I got away with it but I had some uncertain moments. I used to be deaf and my hearing is far from perfect and now I seem to have a problem with handling the camera that I hadn't thought about before. Fortunately I have a position within the team that has its needs; my knowledge of light and the theory, being able to write curricula and teaching materials.
