Whether the visual acuity of 4.4 can be corrected or not should be judged according to the specific age and developmental stage and refractive status, etc. If refractive error is caused by full development, correction is mostly needed.
It is important to distinguish whether the visual acuity of 4.4 is naked eye vision or corrected vision: for naked eye vision of 4.4, if the visual acuity can be significantly improved after correction such as optometry and lenses, it can be corrected; for children, teenagers and adults with fully developed vision, timely and effective refractive error correction can control the progression of myopia and improve the quality of life.
In addition, if the corrected visual acuity is only 4.4, there is no need for vision correction if other eye diseases are ruled out as the cause of vision loss and if there is no significant improvement in visual acuity through corrective measures such as glasses and optometry.
If there is a persistent and sudden decrease in visual acuity, it is necessary to consult a doctor in time, improve the slit lamp microscope and other auxiliary examinations, and choose the treatment of the primary disease or lens correction according to the specific circumstances, and after adulthood, if the conditions permit, it can be surgically corrected.
