If text looks faded or hard to distinguish from the background, increasing contrast can help significantly.

On iPhone

2. Turn on Increase Contrast
3. Turn on Bold Text
4. Turn off Transparency (reduces blurred/translucent backgrounds that can make text harder to read)

3. Some phones also offer Color Correction settings if you have color vision differences
