Detailed answer

Hyperpigmentation is usually caused by an overproduction of melanin, the pigment responsible for skin color. Constant use of eyeglasses or contact lenses does not directly contribute to the development of hyperpigmentation. However, wearing glasses or contacts for prolonged periods may lead to dark circles or discoloration around the eyes due to friction or pressure on the delicate skin. This can create the appearance of hyperpigmentation, but it is a different issue. Factors such as genetics, sun exposure, hormonal changes, and skin trauma are more commonly associated with hyperpigmentation. If you're experiencing concerns about skin discoloration, it's advisable to consult a dermatologist for proper diagnosis and treatment options.
