What does N5 vision mean?

These are of a standard size and ‘normal’ near vision is known as N6, with ‘N’ referring to near and the ‘6’ referring to the size of the letters; N5 is better than N8, for example. You should wear glasses if you need them to read or for close work.

How far can a normal eye see 20/200?

If a patient sees 20/200, the smallest letter that they can see at 20 feet could be seen by a normal eye at 200 feet. This is the Snellen Acuity (English). In Metric Acuity, 20/20 equals 6/6. The conversion is that 20 feet equals approximately 6 meters (actually 6.096).

How to measure your visual acuity for distance?

The typical way to measure your visual acuity for distance has been using the Snellen Eye Chart. The natural vision students who want to improve their distance vision can benefit by reading the Snellen Chart. The Snellen Eye Chart was developed in 1982 by Herman Snellen, a Dutch ophthalmologist, to measure people’s visual acuity.

When does average visual acuity drop to 20/20?

Average acuity in a population sample does not drop to the 20/20 level until age 60 or 70. This explains the existence of the two lines smaller than 20/20: 20/15 and 20/10. When checking visual acuity, one eye is covered at a time and the vision of each eye is recorded separately, as well as both eyes together.

What is the difference between 20/20 and 20/40 vision?

The 20/40 letters are twice the size of 20/20 letters; however, it does not mean 50\% vision since 20/20 sounds like it is one half of 20/40. If 20/20 is considered 100\% visual effiency, 20/40 visual acuity is 85\% efficient. If a patient sees 20/200, the smallest letter that they can see at 20 feet could be seen by a normal eye at 200 feet.
