For comfortable and healthy contact lens wear, oxygen must reach the cornea. Insufficient oxygen can cause discomfort, dryness, and potentially serious eye problems. This is why oxygen permeability testing is so important. It measures how much oxygen can pass through a contact lens material, ensuring adequate oxygen supply to the eye. Various methods exist to measure oxygen permeability, each designed to accurately quantify a lens's ability to "breathe." This measurement is expressed as Dk/t, where D (Diffusivity) represents the rate at which oxygen moves through the material, and k (Solubility) indicates how much oxygen can dissolve within the material, t refers to the thickness of the lens. A higher Dk/t value signifies greater oxygen flow to the cornea, minimizing the risk of hypoxia (oxygen deficiency). ISO 18369 provides a general framework and defines terms related to contact lenses, including oxygen permeability. It specifically outlines the procedures for both pol...

The simple act of opening a milk carton can sometimes be surprisingly frustrating. A poorly designed or manufactured pull tab can lead to broken fingernails, spills, and general annoyance.
