The recovery of blurred vision first depends on the cause of the blurred vision, and then, according to the cause, symptomatic treatment is performed to restore vision. There are many causes of blurred vision, including fundus retinopathy, optic neuropathy, refractive media clouding (cornea, crystal, vitreous, etc.), and refractive errors (including myopia, hyperopia, astigmatism, etc.), all of which can cause blurred vision. There are many types of fundus retinopathy, and the cause needs to be clearly identified for targeted treatment. Treatment methods include the use of circulation-promoting drugs, glucocorticoid steroid hormones, etc., vitreous cavity injection of anti-vascular endothelial growth factor drugs, fundus laser or retinal surgery, but blurred vision caused by fundus retinopathy is more difficult to recover, especially when it affects the macula. Clouding of the refractive media such as the cornea, lens, and vitreous can be treated with appropriate surgery. Refractive errors such as myopia, hyperopia and astigmatism can be corrected by optometry and glasses, or if you don’t want to wear glasses, the right person can also undergo laser refractive surgery to restore vision in adulthood. To sum up, if blurred vision occurs, it is recommended to go to the hospital immediately for a formal examination to clarify the cause and to carry out symptomatic treatment to promote vision recovery so as to avoid irreversible vision damage.
