The same contact lens may never change. But your eyes do change.
Over the years, you might use your eyes on the computer 7-8 hours a day instead of 0.5 hour. Over the last five years, you might use smart phone or tablet to read or write notes and emails. You might be taking allergy medications during some time of the years. These are all factors that can cause dry eye or contact lens intolerance.
Your oils glands around the eyes that secrete the oily layer of the tears to lubricate the eyes may lose a few over the years. These can cause physiological changes in and around your eyes.
For some individuals, the base curve or the size of the eye may also change over the years of contact lens wear.See an Optometrist yearly for contact lens consult.
