Although the human eye’s complexity is extensive, it is unable to handle time prolonged computer screen viewing, as the eyes are most comfortable switching between various focal distances and light complexities. Chris’ eyes will be under extreme strain due to her age and slowly degrading eye functionality, as well as the constant use of a digital screen. The pressure on the eye from an iPad screen is due to the screens fixated distance, which is not encouraging the activity of the eye. Two sets of muscles work in synergy to establish an adequate focus on objects, the first set converges the eyes to the same point, whereas the other flexion allows the lenses in each eye to focus the light produced by the computer screen onto the eye. As looking at an iPad screen forces the eyes to constrict vigorously, the repetitive action with limited eye movement can overwork her eyes, potentially causing spasms of the ciliary muscles forcing the focus to “lock”, which can depict why she is finding it hard to see objects in the distance clearly. Using the iPad screen comprised of screen contrast, flickers and glares does not help Chris’ eyes, as her eye flexion and contraction and focusing on near and far objects will become impaired the older she becomes. Through the constant use of screens at her workplace, Chris’s eye muscles will constantly be contracting when focusing on something close, the eyeball becomes elongated, which will make someone more short-sighted as opposed to being able…
