Vision loss refers to a decrease in the ability to see, which can happen gradually or suddenly. It can affect one or both eyes and may result from various causes, such as aging, injury, or diseases like glaucoma or cataracts. People experiencing vision loss may find it challenging to read, recognize faces, or navigate their surroundings. There are different types of vision loss, including partial vision loss, where some sight remains, and total blindness, where no sight is present. Many individuals with vision loss can still lead fulfilling lives by using assistive devices, such as magnifiers or screen readers, and by receiving support from professionals and loved ones.
