Brightness Acuity Test
MARCO BAT Brightness Acuity Tester is a handheld
instrument designed for two major visual function
1) Brightness Acuity Test – Many people with cataracts and other
ocular media opacities are visually disabled in bright light conditions
from intraocular light scatter often referred to as glare. The BAT Brightness
Acuity Tester provides objective measurements of functional visual acuity
in three common bright light conditions while the is in the standard refracting
2) Macular Photostress Test – The BAT Brightness
Acuity Tester produces a full hemispherical light source
to photostress the retina when maculopathy is suspected.
The BAT Brightness Acuity Tester can simulate three
bright light conditions:
- 1) High-direct overhead sunlight;
- 2) Medium-partly cloudy day;
- 3) Low-bright overhead commercial lighting.
The visual acuity measurements will be similar to those
that would be measured in these three conditions using a standard eye
chart ¹. The result is an assessment of functional visual acuity
which can be obtained in the standard refracting lane.
HIGH (400 ft. lamberts*)
Equivalent to the patient being in direct overhead sunlight (10,000
ft. candles) and standing on a white concrete sidewalk or sandy
MEDIUM (100 ft. lamberts*)
Equivalent to the patient being in indirect sunlight (2500 ft. candles)
and standing on a white concrete sidewalk or sandy beach on
a cloudy day.
LOW (12 ft. lamberts*)
Equivalent to the patient being in bright overhead fluorescent
lighting (300 ft. candles) such as in a department store, plant assembly
line or classroom.
