The effectiveness of computer screen filters

Collins, Michael J., Goode, Andrew, & Atchison, David A. (1993) The effectiveness of computer screen filters. Clinical and Experimental Optometry, 76(3), pp. 91-100.


We have compared the performance of a variety of computer screen filters which are currently available in Australia. The filters tested included six neutral density filters and 10 mesh filters. The testing incorporated measurements of the filters’ effectiveness in reducing the luminance of specular and diffuse reflections, along with an analysis of the effect of the filters on screen luminance / contrast at a variety of viewing angles (from 0 degrees to 50 degrees). As groups, the neutral density filters with antireflection coatings and mesh filters performed significantly better than neutral density filters without antireflection coatings in reducing the luminance of specular reflections. The diffuse reflections, the neutral density filters with antireflection coatings performed significantly better than mesh filters in reducing the luminance of the reflections. The performance of mesh filters in reducing specular reflections was significantly positively correlated with the density of the mesh. All filter types caused reductions in screen luminance and contrast with increase in off-axis viewing angles.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
