If the eyes are blurred in the near but clear in the distance, it is considered to be caused by insufficient adjustment ability, which is more common among the elderly. As we age, the adjustment ability of the eyes gradually decreases, and when it reaches a certain level and cannot compensate for the need to use the eyes at close range, it will lead to blurred vision. You should go to the hospital in time for an optometrist and wear a pair of presbyopic glasses to compensate for the adjustment ability of the eyes, so that you can see clearly near. However, if you do not see clearly near and far, you should consider organic eye disease and go to the hospital to check whether there is cataract or fundus disease, such as macular degeneration. If these lesions are present, for example, cataracts may require surgery, and lesions of the fundus may require injections, laser, or in some cases, surgery.
