Diminished Contrast Sensitivity and Macular Degeneration January 18, 2024 |
Hello Diminished Contrast Sensitivity and Macular DegenerationVery often when one learns about the symptoms of macular degeneration, the focus is on one's sharp, central vision. Blurriness in the middle of one's sight affects visual acuity which can interfere with the ability to read or to recognize faces. A visual acuity test uses the Snellen Chart which uses high contrast dark black letters on a white background. However, another common change in vision for those with age-related macular degeneration is diminished contrast sensitivity - the ability to see and distinguish low contrast objects such as sorting and pairing up black and navy blue socks or seeing a white car on a snowy day. Low light or dark cloudy days makes it even more difficult to detect or identify low contrast images - such as light grey words on a dull white background. Diminished contrast sensitivity can also interfere with one's independence and safety making it unsafe to drive at night or to detect an upcoming curb on a sidewalk. Just as there is a test for visual acuity one can also be tested for contrast sensitivity. Find out more about how one can enhance the ability to distinguish contrast and what test can be done by your eye doctor.
