These lenses are designed to alleviate eye strain and visual discomfort experienced during prolonged near-vision tasks, such as reading, computer use, or mobile device interaction. They incorporate a slight power boost in the lower portion of the lens, aiding the eye’s focusing muscles and reducing the effort required for close-up activities. This additional power, typically subtle and unnoticed during distance viewing, helps to minimize accommodation fatigue and improve visual clarity at near distances.
The significance of these lenses lies in their ability to enhance visual comfort and reduce symptoms associated with digital eye strain, also known as computer vision syndrome. These symptoms may include headaches, blurred vision, dry eyes, and neck or shoulder pain. By easing the focusing burden on the eyes, these lenses can contribute to increased productivity, improved concentration, and an overall better visual experience, particularly for individuals spending extended periods engaged in near-vision activities. The development of these lenses represents a response to the increasing prevalence of digital device usage in modern life and the subsequent rise in eye strain complaints.
