Depth of Field, Vision!

12 Jul

I was a little bit “depressed” (not seriously, just a little de-motivated) as of late because I have been hovering at almost -4.00 vision (my far distance vision is not super pin-sharp with that level yet).

I’ve been asked on several occasions — by well-meaning people who know I’m on this natural vision improvement program — how my “eye exercises” are going.

The Bates Method is about re-learning healthy/natural eyesight habits, not eye exercises, so I have persevered in keeping the main principles in mind.

I remember reading in Thomas’s book (that’s based on Bates’ work) something about:

(1) Spatial Awareness
(2) Colour
(3) Depth of Field in natural surroundings.

I didn’t really have a good understanding of what he was talking about. I understood what he meant “in theory,” but in actuality, my vision was so bad that the depth of field made no difference whatsoever! (with wearing glasses vs. not wearing glasses.)

Today I was wearing non-prescription sunglasses (I bought a whole bunch because of a clearance sale), so everything was quite blurry with my “around -4.00” vision.

But it was a sunny day. I noticed that my peripheral vision was stronger when I took the sunglasses off. When I put them back on again I made a note about this “peripheral vision” so that my eyes/brain registered it.

Imagine my shock/surprise when I started seeing what the whole “depth of field” thing was about (!!!). Without my glasses, things are fuzzy to an extent — but I could see the form/outline of objects (plants, books on shelves, whatever), in a 3-dimensional way. When I put my glasses back on, things are sharper, but that 3-dimensional DEPTH OF FIELD is compromised (things become more 2-dimensional instead).

DAMN! That’s just the kind of motivation I need to continue on this natural vision improvement program :)

NOTE: “A person may have better vision in daylight than at night because of an increased depth of field.” — http://en.wikipedia.org/wiki/Depth_of_field 

My whole life, I have always noticed that my eyesight was better in strong sunlight. I wasn’t imagining things!!

    That’s so true… When I started practising the sketch, breathe, blink ‘exercise’ I suddenly saw trees and cars etc popping out at me – like crazy drawings from some colorful kids’ cartoon. And my acuity had not improved one bit, but it proved to me that I was missing out wearing those specs…
