What is blurred vision in the right eye?

There are many reasons for blurred vision in the right eye. The most common ones are: first, visual fatigue. If you use your eyes excessively for a long time or stay up late, you may show blurred vision for a long time. This situation can be restored to normal after rest, less use of eyes, and reduced use of electronic products. Second, refractive errors. For example, myopia, hyperopia, astigmatism, or improper glasses originally worn will show blurred vision. You need to go to the ophthalmology department for optometry and glasses, most of which can be improved. Third, there may be some eye diseases, such as cornea, iris, lens, retina, optic nerve and other diseases, may show blurred vision. Therefore, once blurred vision is shown, it is recommended to see an ophthalmologist as soon as possible.
