Effect of decreased subcutaneous fat around eye
Leads to decreased near vision
Effect of decreased eye tone and elasticity
Leads to poor eye coordination
Effect of decreased strength of eye muscles
Leads to distortion of images
Effect of weakening of levator palpebrae superioris
Leads to problems with upward gaze, convergence, poor eye coordination, and difficulty focusing
Effect of decreased cornea transparency
Leads to blurred vision, decreased cornea sensitivity, and decreased visual field
Effect of cornea thickening, flattening, become more rigid, and less smooth
Leads to astigmatism and blurred vision
Effect of degeneration of sclera, pupil, and iris
Leads to compromised night vision
Effect of increased density and rigidity of lens
Leads to loss of color sensitivity to green, blue, and violet
Effect of pupil size decreases and senile miosis (more fixed pupil)
Leads to impaired depth perception (appears further than they are) and driving ability
Effect of increases in connective tissue, sclerosis of blood supply, and muscle weakness of eye
Leads to decreases in iris dilation, gradual loss of visual acuity, difficulty seeing in low lighting
Effect of decreases in rod density and retinal nerve fiber thinning
Leads to narrower field of vision, difficulty seeing in low light, problems with light/dark adaptation, and increased sensitivity to glare
