At birth, the amplitude of accommodation is approximately 16 diopters (D), which is reduced to about 7–8 D by the age of 25 and about 1–2 D by the age of 60. These age changes are called presbyopia. 4 For myopia the image is projected behind the retina (a), and for hyperopia it is projected in front of the retina (b). 4 REFRACTIVE ERRORS Many people have difficulties in focusing on objects due to myopia (near-sightedness), hyperopia (far-sightedness), astigmatism (the vision along vertical axis is different from the horizontal axis), and presbyopia (changes due to age).

As we can see in the figure, the threshold curve for the rods goes below the threshold curve of the cones. This means that the rods are more sensitive and can respond to less light energy than the cones. The second, or scotopic, phase results from regeneration of rhodopsin in the rods. There is a thousand-fold increase in sensitivity, and the dark adaptation is finished in about 30 to 40 minutes. 6 COLOR VISION Visible light ranges in wavelengths from 380 nanometers (nm) to 760 nm. This corresponds to the colors violet, indigo, blue, green, orange, and red.

There were no negative effects of the new system. Operators generally appreciated what had been done and were happy with the new system. These types of improvements are more tangible and difficult to quantify in terms of cost savings than are improvements in productivity and safety. CONCLUSIONS From a scientific point of view the study was unsatisfactory. There was no control group that can be used to compare the results. Therefore we cannot easily substantiate the claim that the benefits were due to ergonomic improvements.
