Google Glass wearers tested for blind spots

Researchers at the University of California studying the effect of wearable head-mounted displays on visual function have found that Google Glass caused blind spots in the upper right area of the visual field, according to results published in the Journal of the American Medical Association.

Three individuals with 6/6 best-corrected visual acuity and normal visual fields were tested after using the Glass device for the manufacturer-recommended acclimatisation period of 60 minutes.

Assessments were then made as to potential obstructions and researchers graded Glass’ display prism position relative to the right eye pupillary axis in three categories: over central pupillary axis; above central pupillary axis but inferior to superior limbus; and finally superior limbus.
