What is the term for the vision severity of 20/70 to 20/100?

1. Normal vision

2. Moderate vision impairment

3. Legal blindness

4. Severe vision loss

The correct answer is: Moderate vision impairment

The term for the vision severity ranging from 20/70 to 20/100 is classified as moderate vision impairment. This range indicates that a person with 20/70 vision can see at 20 feet what a person with normal vision can see at 70 feet, while someone with 20/100 vision sees at 20 feet what a person with normal vision can see at 100 feet. In this category, individuals may experience difficulties with tasks such as reading small print or recognizing faces at a distance, but they usually retain some degree of functional vision. Understanding this classification helps in addressing the specific needs of individuals with moderate vision impairment, including potential accommodations in educational settings to support their learning and daily activities effectively. The other classifications mentioned are for different levels of visual acuity; for instance, normal vision indicates acuity better than 20/40, legal blindness refers to a visual acuity of 20/200 or worse, and severe vision loss is recognized typically when acuity is significantly impaired beyond moderate impairment.
