So How Do We Lose Our Sight?
OK, here’s a bit more technical stuff about the process of ‘seeing’. If you’re not that
bothered about understanding the mechanics of it all, click the button below and
skip straight to the ‘no brainer’ explanation.

The Theory of Accommodation
In order to "see" properly, the eyes must accommodate. Accommodation takes
place when you are focusing on various distances, close and far.
Which muscles are doing the focusing during accommodation is debatable among
Ophthalmologists. In fact, it’s quite a hotly debated topic, and the jury is still out on
the verdict, but here are the basics…
Dr. Helmholtz, an early eye doctor, ‘postulated’ that only the Ciliary Muscle does
the accommodating. The Helmholtz Theory is the ‘accepted belief’ of most modern
eye-glass doctors.
Dr. Bates, a natural eye specialist, disagreed. He felt that the two oblique eye
muscles were involved in eye accommodation, by compressing the
round eyeball in the middle and making it longer horizontally.
To demonstrate his theory, Dr. Bates cut these muscles in rabbits
and found the eyes could no longer accommodate. He also tried
injecting a drug to paralyze the oblique muscles, and found that the eyes also
failed to accommodate.
