Contact Lenses block oxygen supply to your eyes.
Oxygen is very essential for the visual cells in our eyes. It’s like fuel to a car ! The retina which is responsible for the first stages of the visual process has a limited blood supply, so there’s a delicate balance between the high oxygen demand of our retinal cells and a limited supply. Oxygen is the most supply-limited substance in the human retina. When a slight imbalance occurs in the eye due to a lack of oxygen, our retina is stressed and this can lead to various eye diseases.
