Vision

A customer must meet all of the following visual standards to be eligible for a School Bus, 7D, or 7D½ certificate:

1.  Visual Acuity and Horizontal Peripheral Field of Vision Standard:

a.  At least 20/40 distant visual acuity (Snellen) in each eye, with or without corrective lenses, and not less than 120 degrees combined horizontal peripheral field of vision

b.  A “B” restriction (corrective lenses) must be put on the permit/license when corrective lenses are used to meet this standard

c.  A customer who uses bioptic telescopic lenses is not eligible to receive a School Bus, 7D, or 7D½ certificate

2.  Color Vision Standard:

a.  A customer must be able to distinguish the colors red, green and amber 

3.  Vision Impairment Standard:

a.  A customer must not have unresolvable diplopia (double vision which cannot be resolved by wearing an eye patch or other suppressive device) 

 

20/20 is excellent visual acuity and 20/200 is legally blind.  20/40 vision is better than 20/50 vision, 20/50 is better than 20/60, 20/60 is better than 20/70, and so on.

 

The term “at least 20/40,”as used in the visual acuity standards means 20/40 or better. 20/40, 20/30, or 20/20 visual acuity would all be acceptable for an unrestricted certificate.  20/50 or 20/60 would not be acceptable. 180 degrees horizontal peripheral field of vision is a full field of vision.  170 degrees is better than 160 degrees, 160 degrees is better than 150 degrees, and so on.

 

The term “not less than 120 degrees,” as used in the horizontal peripheral field of vision standard means 120 degrees or more- 120 degrees, 130 degrees, or 140 degrees horizontal peripheral field of vision would all be acceptable.  115 degrees or 110 degrees would not be acceptable.

 

To apply for a 7D, or 7D½ certificate, a customer must have the medical information section of the 7-D School Pupil Transport Certificate Application completed by a physician.
