Starting the day with natural daylight, especially during the early morning hours, may help support the eyes’ focusing performance throughout the day.

Extended exposure to artificial lighting in indoor environments may increase feelings of eye fatigue. Natural light helps the eyes perceive environmental contrast more effectively. Short outdoor walks in the morning can be particularly beneficial, supporting the eyes’ adaptation to daylight. While daylight plays a role in regulating the body’s biological clock, it also contributes to communication between the eye’s light-sensing system and the brain. Time spent in natural light allows the eyes to focus at varying distances and helps reduce the visual strain associated with prolonged near-work activities. Outdoor environments also provide a welcome break from the constant exposure to screens and artificial lighting that many people experience throughout the day. For this reason, spending even short periods of time outdoors can be considered a valuable habit for maintaining visual comfort.

Irregular sleep schedules and spending long periods indoors may contribute to increased visual fatigue. Insufficient exposure to daylight can negatively affect visual comfort, particularly among individuals who spend much of their day working in front of screens. Taking short breaks outdoors during the day supports both mental relaxation and eye recovery. Exposure to natural light in the morning may help maintain attention levels, while balanced daylight exposure throughout the day can help reduce screen-related visual fatigue. Even brief periods spent outdoors can help the eyes rest, and small changes to daily routines may have a positive impact on both eye health and overall quality of life.
