The international glass code is based on U.S. military standard MIL-G-174, and is a six-digit number specifying the glass according to its refractive index n d at the Fraunhofer d- (or D 3-) line, 589.3 nm, and its Abbe number V d also taken at that line.
[16] [18] Several studies have shown that blue light from computers does not lead to eye diseases, including macular degeneration. [16] [19] [20] The total amount of light entering the eyes can be adjusted without glasses using the screen brightness settings. Similarly, the blue light can often specifically be adjusted using the "night mode" of ...

The structure of glasses differs from the structure of liquids just above the glass transition temperature T g which is revealed by the XRD analysis [10] and high-precision measurements of third- and fifth-order non-linear dielectric susceptibilities. [11] Glasses are generally characterised by a higher degree of connectivity compared liquids. [12]
Pint glasses commonly have a fill line for the volume of one-half of an imperial pint (284 ml). Although the glass must be accurately-calibrated, industry guidelines only require a pint to be at least 95% liquid, allowing 5% of the pint to consist of the foamy ' head '.
