When the human eye sees far and near, it uses the ciliary muscle and the lens to regulate each other. The ciliary muscles are tense when looking close up and relaxed when looking far away. Working at close range for a long time can easily lead to eye fatigue. Possible symptoms include frequent blinking, burning eyes, tearing, headaches, and inability to concentrate. .
On the other hand, the pressure-relieving lenses are designed with the upper half of the lens suitable for distance viewing and the lower half of the lens for near viewing. Combining the two different prescriptions into one lens allows you to see far away clearly, near comfortably, and your eyes are less uncomfortable. Eye fatigue, and anti-stress lenses are suitable for all age groups such as students, office workers, etc., because eye fatigue is regardless of age.
