Question

Threshold for vision referral for kindergarten or younger

A) 20/20 vision
B) 20/30 vision
C) 20/40 vision
D) 20/50 vision

Answer 1

For kindergarten or younger children, a vision referral is typically recommended if they have visual acuity worse than 20/40. This evaluation is commonly done using a Snellen chart to assess visual acuity, and if the threshold is not met, a further examination by an eye care professional is advised.

Step-by-step explanation:

When considering the threshold for vision referral for kindergarten or younger, the typical standard is at 20/40 vision. If a child is unable to achieve this level of visual acuity, it may be an indication that they require further examination by an optometrist or ophthalmologist. Visual acuity is assessed using tools such as the Snellen chart, which measures how well a person can see at various distances. An important concept is the ability of the eye's lens to change its power to focus on objects at different distances, which is referred to as accommodation. However, for the specific question about referral for children, if a child has visual acuity worse than 20/40, a referral for further examination is recommended.
