What Are Contrast Sensitivity Issues With Vision?

Contrast sensitivity is the ability of the visual system to distinguish between areas of different brightness or color. People with normal contrast sensitivity can easily see the difference between a light gray object and a dark gray object, even if they are very similar in brightness. People with contrast sensitivity issues may have difficulty seeing the difference between these objects, especially in low-light conditions.

Contrast sensitivity issues can be caused by a variety of factors, including:

* Age: Contrast sensitivity decreases with age, especially after the age of 60.

* Eye conditions: Certain eye conditions, such as cataracts, glaucoma, and macular degeneration, can cause contrast sensitivity issues.

* Neurological conditions: Some neurological conditions, such as multiple sclerosis and Parkinson's disease, can also cause contrast sensitivity issues.

* Medications: Some medications, such as antidepressants and antihistamines, can cause contrast sensitivity issues as a side effect.

Contrast sensitivity issues can make it difficult to perform everyday activities, such as reading, driving, and walking. People with contrast sensitivity issues may also be more sensitive to glare and may have difficulty seeing in low-light conditions.

There are a number of things that can be done to help improve contrast sensitivity issues, including:

* Using brighter lights: Increasing the amount of light in a room can help to make objects more visible.

* Reducing glare: Glare can be reduced by using blackout curtains or blinds, or by wearing sunglasses outdoors.

* Using contrast-enhancing filters: Contrast-enhancing filters can be used to improve the contrast between light and dark objects.

* Using magnifiers: Magnifiers can help to enlarge objects and make them easier to see.

If you are experiencing contrast sensitivity issues, it is important to see an eye doctor to determine the cause and to discuss treatment options.
