The process by which certain muscles (called ciliary muscles) function, to change the focal length of the eyes so that the image is clearly formed on the retina is called the accommodation of the eye. You can actually put this power of your eye to test.This will vary for near and distant objects and also for objects moving away or towards the eye. Keep your finger in front of you and try to focus only on the finger. So how does this accommodating power work considering varying distances?By adjusting the focal length, the eye is actually changing its lens power as well isn’t it? You will notice that objects in the background tend to get blurry. Keep your finger in front of your face but focus on something in the background. If the object in consideration is at a distance, for the image to form at the retina, the focal length has to be large.Here, the ciliary muscles relax, thereby thinning the eye lens.A few other guys joined the club in the following few years; their progress was slow but steady. I liked the idea of attaching chains to the bar, so me and Joe Amato decided to give it a try for our next meet.We cycled the chains on our dynamic day for eight weeks. We both put 60 pounds on our squats and became the next two to join the 800-pound club. The chains were introduced to the rest of the gym and within the next year we had another six guys in the 800s.This causes a reduction in the focal length for ideal image formation.The Power of accommodation for a person with normal eyesight is around 4 dioptre (unit of lens power).
I told him I thought it was a waste of time but went along any way, you know, so he wouldn't kick my ass.Not only were the chains working for the squats, but all of our benches were going through the roof as well!We were always used to slow, steady gains, but were now seeing dramatic increases in a very short time. Then about three years ago, Louie asked me to go to a basketball conference with him to check out some bands.The name didn't matter; what mattered was if it worked or not.I've seen some of the strangest things created using cables, boxes, benches, rings, dumbbell bars, you name it.
The human eye, with its various parts, plays a very important role in our lives. This may seem simple enough to just say it like that but a series of operations occur from the point of light rays entering our eyes till we perceive the image of whatever we are seeing.
