Nägemisväsimus

Nägemisväsimus, also known as asthenopia, refers to a condition characterized by eye strain, fatigue, or discomfort, often resulting from prolonged near work, reading, or using digital devices. This condition can manifest as symptoms such as blurred vision, dry eyes, headaches, and general eye discomfort. Nägemisväsimus is commonly associated with the use of computers, smartphones, and other digital screens, as well as with activities that require close-up work, such as reading or crafting.

The primary causes of nägemisväsimus include prolonged exposure to near work, poor lighting conditions, and the use of inadequate visual aids. The 20-20-20 rule is often recommended to mitigate eye strain: every 20 minutes, look at something 20 feet away for at least 20 seconds. This practice helps to reduce eye strain by allowing the eyes to rest and refocus.

Preventive measures for nägemisväsimus include maintaining a healthy distance from the screen, using proper lighting, and taking regular breaks to rest the eyes. Additionally, ensuring that the screen is at the correct height and angle can help reduce strain. For those who experience frequent episodes of nägemisväsimus, consulting an eye care professional may be necessary to rule out underlying conditions and to receive personalized advice on managing the condition.
