Impaired Dark Adaptation: Earliest Sign of AMD
The earliest warning sign of age-related macular degeneration is trouble seeing at night. Many people blame night vision problems on the normal aging process. But it could be something more.
If you begin having difficulty seeing or driving at night, it’s time to talk with your doctor. You may have impaired “dark adaptation.”
What is Dark Adaptation?
Dark adaptation is the ability of your eyes to adjust from seeing in the light to seeing in the dark. Think of going from bright sunlight into a darkened movie theater. How long does it take your eyes to adjust? That is dark adaptation.
Research shows that dark adaptation weakens at the earliest stages of AMD. This is why you might experience troubles seeing driving at night, reading in dim light, or adjusting to seeing in the dark. As the disease progresses, night vision difficulties increase.
The first AMD symptom I noticed was problems reading in a dim room. When the light was bright, I had no issues. But when the light was dimmed, I just could not make out that small print.
Breakthrough in Dark Adaptation Testing
By testing night vision with a new tool, called AdaptDx, you doctor can identify AMD much earlier than with any other test.
