Day mode refers to a setting or feature in devices and applications that enhances visibility and usability during daylight hours. This mode typically increases brightness and adjusts color contrast to make content easier to read in bright environments. It is commonly found in smartphones, tablets, and computer screens. In addition to improving visibility, day mode often reduces glare and may include features like a blue light filter to minimize eye strain. Users can switch to day mode manually or set it to activate automatically based on the time of day, ensuring optimal viewing conditions throughout the day.
