• growth of lens

• increased intraocular light scatter
• diminished light reaching photoreceptors c increased opacity of lens & vitreous humor

• decreased accomodation ( presbyopia)
• decreased visual acuity

• largely decrease in dynamic acuity (moving target)

• decreased depth perception
• decreased color sensitivity
• decreased contrast sensitivity
• change in the axis of astigmatism
• decreased corneal sensitivity
• poor light/ dark adaptation
• retinal pigment epithelium changes
• endothelial changes ( atherosclerosis)
• increased pressure in anterior chamber
• decreased lacrimation
