Nearsightedness, or myopia, occurs when the light rays converge in front of the Retina.1 Myopic people can generally see well for close-up task such as reading and computer use; but will have difficulty seeing distant objects clearly (example: road signs) without eye glasses or contact lenses.1,2 Other signs and symptoms of uncorrected myopia include squinting, eye-strain and headaches, and may also include feeling fatigued when driving or playing sports.1
Myopia generally occurs when the eyeball is too elongated relative to the focusing power of the cornea and crystalline lens of the eye.1
A patient with myopia is prescribed a ‘minus’ powered corrective lens.1 Depending on the degree of myopia, glasses or contact lenses may be recommended for use full time or only during specific activities, such as driving or playing sports.1,2
Myopia typically shows up in early childhood, and progressively worsens until it stabilizes in early adulthood.1,2
