My eyes are always blurry, what's going on?

Nowadays, many people always feel blurred vision from time to time in their daily lives. Generally, blurred vision can be divided into several types, including viral infection, strabismus, amblyopia, eye trauma, and eye perforation. These are the main causes of blurred vision. In addition, we should pay attention to it in daily life. If the blurred vision is more serious, we need to check it out and never delay the condition.

Blurred vision refers to visual acuity below 1.0, and below 0.30 for impaired vision. Vision is mostly used to distinguish small or distant objects.
