Myopia Usually myopia is caused by the lengthening of the eye axis due to genetic factors or acquired bad eye habits, etc., while presbyopia is caused by ageing, which leads to the loss of lens elasticity, and the two are different disorders that can occur at the same time. Therefore, myopic patients can also develop presbyopia as they age. Myopia causes the focus of light rays entering the eye to not be able to focus on the plane of the retina, but rather on the front of the retina, resulting in blurred vision, which can be corrected with eyeglasses to improve visual acuity. Patients with presbyopia can also correct their presbyopia by wearing presbyopia glasses to improve their vision. It is recommended that patients with presbyopia or nearsightedness consult a doctor in a timely manner to assess their condition and follow the doctor’s instructions for treatment.
