Lähityö

Lähityö is a Finnish term that translates to "near work" or "close work" and refers to tasks that require focusing on objects or activities at a close distance. This typically includes activities such as reading, writing, using a computer, sewing, or any other activity where the eyes are directed towards something within arm's reach. The concept of lähityö is often discussed in the context of vision health, particularly concerning the development and progression of myopia (nearsightedness) and eye strain.

Prolonged periods of lähityö are frequently cited as a significant factor contributing to visual fatigue, headaches, and dry eyes. In children, excessive close work is also a growing concern for eye care professionals, as it is believed to be a contributing factor to the increasing prevalence of myopia. Conversely, spending time outdoors and engaging in distant viewing is often recommended as a counterbalance to mitigate the negative effects of extensive lähityö.

The digital age has amplified the amount of time many individuals spend on lähityö due to increased screen time for work, education, and leisure. This has led to greater awareness and research into ergonomic practices, visual hygiene techniques, and the potential long-term impacts of sustained close visual focus. Strategies to manage the effects of lähityö include taking regular breaks, ensuring adequate lighting, maintaining proper posture and working distance, and incorporating outdoor activities into daily routines.
