On a duochrome test, if the RED side appears clearer, what does that
indicate and what should you do?
The patient is residually myopic (focus in front of the retina), so you should
add minus (−) to shift the focal point back onto the retina
On a duochrome test, if the GREEN side appears clearer, what does it
indicate and what should you do?
The patient is residually hyperopic (focus behind the retina), so you should
add plus (+) to shift the focal point forward onto the retina
,What is the endpoint of the duochrome test?
The endpoint is when the red and green sides appear equally clear, indicating
the
circle of least confusion is on the retina (proper focus)
What does “RAMGAP” help you remember in the duochrome test?
Red → Add Minus

Why is bichrome (red/green) balance preferred for patients with unequal visual
acuity?
Because the goal is to equalize accommodative stimulus between the two eyes,
not to equalize visual acuity
,What does it indicate if letters on the red background appear clearer and darker
during a duochrome test?
The eye is residually myopic, meaning the focus is in front of the retina
In a residually myopic eye, how do letters on the green background appear
during the duochrome test?
They appear slightly blurry, less dark, and with less defined borders
During duochrome testing, where is the focal point located if the red side
appears clearer?
In front of the retina
, During a duochrome test, what does it indicate if the red side appears clearer?
The eye is residually myopic, so add minus lenses
During a duochrome test, what does it indicate if the green side appears
clearer?
The eye is residually hyperopic, so add plus lenses
How should an emmetropic eye perceive the duochrome chart?
Both red and green sides should appear equally clear, dark, and well defined
During a duochrome binocular (Humphriss) test, what does it mean if the
patient reports no change regardless of the lenses added?
It suggests suppression, meaning the patient may be ignoring input from one eye
