How to Adjust iPhone Contrast

Low contrast makes it difficult to distinguish light colors from dark colors and, for some users, can lead to difficulty reading on-screen text and headaches. To help alleviate this problem, Apple offers new accessibility options in iOS 7, including the ability to natively increase the contrast on the device. After raising the contrast, you should find that your light and dark colors are more pronounced in all native apps, such as Messages and Mail, and in areas such as the Notification Center.

Open the "Settings" application and tap the "General" row.

Tap the switch next to Increase Contrast. The switch turns green to indicate that the setting is now enabled.

Tap the switch again to decrease the contrast, returning the iPhone back to the factory default settings.
