To prevent glare and reflections: Avoid the use of shiny materials and finishes that can cause glare. This is a tip that some car manufacturers could take to heart, eliminating the bright instrument bezels and glossy surfaces that are common to many dashboards. Drivers don’t want to be “blinded by the light,” as goes the song performed by Manfred Mann and written by Bruce Springsteen.Ensure displays are adjustable so that users can position them to prevent or reduce glare caused by overhead lights or streaming sunlight.Add anti-glare and anti-reflection coatings or films. This is especially helpful for devices commonly used in bright lighting conditions like direct sunlight.Give surfaces—such as a glucose meter’s screen—a matte finish that causes greater light dispersion and reflects less light in a particular direction. But, keep in mind that a matte finish can reduce image quality to a certain degree.7
From Vision Science to Design Practice

Good lighting can make the difference between seeing and not seeing for older adults with poor vision and between comfort and discomfort. Designers, caregivers, allied medical professionals, and other service providers can improve quality and well-being of older people by recommending good lighting to mitigate some of the common problems associated with aging eyes (Figueiro, 2001).Light colors on the walls and ceilings reflect more light in an indoor space, which is often useful. Doors, floors, and furniture should have darker tones to contrast with the walls.The use of plain colors and matte finishes help prevent dazzle, reflections, and glare.Colors in contrasting shades are recommended to highlight furniture, equipment, and potentially dangerous objects and situations. A good color contrast can help in locating emergency exits. Special attention should be given to the location of mirrors to avoid confusion.

A third approach is to decrease reflectance through matte finishes. Car dashboards and satin-finish chrome and stainless steel are examples. Psychologically, people tend to prefer matte blue, green, or brown over gray.

An UVGI box irradiator was built with internal dimensions of 69.5 cm length, 55 cm width, and 33 cm height. Inside, a grating of 58 × 41 × 15 cm was placed to hold the masks. Three 15 W lights HNS 15 W G13 (OSRAM GmbH, Munich, Germany) were located at the upper limit in three of the four walls of the box. Each lamp provided 4.9 W in the UVC wavelength. The plane containing the three lamps was parallel to the bottom. The grating that held the respirators was placed over the bottom. The distance between the lamp plane and the grating was evaluated, and measurements were taken to find the more homogeneous irradiance inside the UVGI chamber. The whole internal surface of the chamber was coated with a matte aluminum insulating lining. Aluminum is known to present a good reflection in the UV-C wavelength range (Bass et al. 2009; Welch et al. 2018). The matte finish improved light diffusion, to provide a safer, more even irradiance distribution—softer shadowing, at the expense of increased irradiation times due to lower reflectivity.
A black electrodeposited copper–tin (Cu–Sn) alloy film for solar thermal absorbers
Published in Transactions of the IMF, 2018
Homogeneity of solar absorber in terms of appearance and thickness is essential to increase the average optical absorption value of the surface. Therefore, organic and inorganic additives are used in the electroplating bath. Matt and rough surfaces are preferred because the bright surfaces reflect the light, which cause the loss of the light on the surface and the surface roughness increases the surface area, which raises the absorption value.
