Our Aging Eyes

How Aging Causes Eye Problems
Just as hair turns gray with age, bladders weaken and memory's lapse, our eyes, too, undergo a metamorphosis. Although these changes are all part of normal aging, some set the stage for more serious eye problems. As our eyes age, eyelid muscles weaken, and skin becomes more flaccid. This can cause the upper eye lid to droop or the lower lid to sag. Eyelashes and eyebrows may lose their lushness and thin out considerably.
Tear production also drops off, and the oily film that tears provide decreases as lubricating glands in the conjuctiva (the membrane covering the sclera (white part of the eye). These changes can lead to a buildup of mucous, resulting in stickiness, or make the cornea dry, causing irritation or an uncomfortable, gritty sensation in the eye.
The conjuctiva turns thinner and more fragile with age and takes on a yellowish tinge from an increase in the elastic fibers. The sclera may also assume a yellowish hue from a collection of lipid, or fat, deposits. Calcium may be deposited in the sclera, leading to patches of grayish translucency. The exposed conjuctiva between the lids begins to degenerate, and the cornea can develop an opaque white ring around its edge.
With time, the crystalline lens hardens and loses its elasticity. This makes it more difficult to focus on near objects, a common condition called presbyopia. You might also find that your night vision grows poorer. These changes usually occur simultaneously in both eyes.
The picture painted above is not pretty, but the good news is an eye doctor can help lessen the effect of these normal processes.

Along with droopy eyes, sagging skin, memory lapse and the weakened bladders associated with aging comes maturity, wisdom and self awareness so don't let minor issues keep you from staying in the game. Those who do continue to be productive, have a lot more fun and contribute much needed expertise to society.
