Opacities

Opacities, in a general sense, refer to the quality or state of not letting light pass through; imperviousness to light. More specifically, it describes the degree to which a substance or medium is opaque. This term can apply to a wide range of materials, from clouds and stained glass to medical imaging results, indicating areas of reduced transparency. The level of opacity can vary greatly, from slight haziness to complete blockage of light, which can result in images with unclear details, or a complete blackness if the object is completely opaque.

Opacities meaning with examples

• The radiologist examined the X-ray, noting several areas of increased opacities in the patient's lungs. These dense regions suggested potential inflammation or infection. Further investigation, including additional scans, was ordered to determine the underlying cause of the opacities and to develop an appropriate treatment plan.
• The artist struggled to achieve the desired effect in their painting because the pigments used created unintended opacities. Areas of the canvas became unexpectedly dense and obscured details of the underlying layers, hindering the ability to achieve the desired transparency.
• Heavy smog created significant opacities in the atmosphere, significantly reducing visibility. The city skyline was barely visible through the thick haze, and flights were delayed due to the potential danger of navigating these opaque conditions.
• The window film provided privacy but also introduced opacities, making it difficult to see outside clearly. While it blocked harsh sunlight, it also restricted the view, creating a sense of being shut off from the outside world.
