20/20 vision and 20/30 vision are terms used to describe the clarity of a person’s vision. The standard vision measurement is called the “Snellen Visual Acuity”, which is usually expressed as a fraction such as “20/20” or “20/30”. 20/20 vision is considered normal, while 20/30 vision indicates a mild degree of vision impairment.
20/20 vision is the standard definition of normal vision, meaning a person can clearly see objects 20 feet away from them with the same clarity as a person with normal vision can from 20 feet away. 20/30 means that a person with 20/30 vision can see objects 20 feet away with the same clarity as a person with normal vision can from 30 feet away.
Having 20/30 vision means that a person’s vision is not as sharp as someone with 20/20 vision, but it is not necessarily a cause for concern. Depending on the person’s occupation or activities, 20/30 vision may not be a problem. However, if a person’s vision is 20/30 or worse, they may need eyeglasses or contact lenses to improve their vision and make daily activities easier.

How Can 20/20 Vision Be Measured?
The standard vision measurement used to determine 20/20 vision is called the “Snellen Visual Acuity”. This is expressed as a fraction, such as “20/20” or “20/30”. To measure 20/20 vision, an optometrist or ophthalmologist will use a chart of letters of different sizes and ask the patient to read the letters aloud. If the patient is able to read the letters 20 feet away with the same clarity as a person with normal vision can from 20 feet away, then they have 20/20 vision.
How Can 20/30 Vision Be Measured?
The standard vision measurement used to determine 20/30 vision is called the “Snellen Visual Acuity”. This is expressed as a fraction, such as “20/20” or “20/30.” To measure 20/30 vision, an optometrist or ophthalmologist will use a chart of letters of different sizes and ask the patient to read the letters aloud.

Causes and Treatments for 20/30 Vision
The causes for 20/30 vision can vary but can include refractive errors such as nearsightedness, farsightedness, astigmatism, and presbyopia. Treatments for 20/30 vision usually involve corrective lenses, such as eyeglasses or contact lenses, to improve vision and make daily activities easier. In some cases, if a person has been diagnosed with 20/30 vision, their optometrist may suggest vision therapy to help improve the clarity of their vision.
