Redness and itching in the eyes may be caused by allergies, dryness, exposure to dust, or eye strain from long screen use. Wearing spectacles with your given power is not usually the direct cause of these symptoms. Try to avoid rubbing your eyes and give them regular rest if you use screens for long periods. Consult a doctor if the irritation continues.

Myopia causes distant objects to appear blurry because light does not focus correctly on the retina. Eye drops usually do not correct this problem, and glasses or contact lenses are commonly used to improve vision. The axis of a lens becomes important when there is astigmatism, as it helps correct the direction of the visual distortion. Consult a doctor for a proper eye examination and guidance.
