The effects of scattered light in the eye: A preliminary study on a glare-based test.
Quercia A., Tesi S., Farini A., Baldanzi E.
Glare causes a loss of efficiency in visual acuity, but its effects are often underestimated although it can generate a decrease in visual acuity even greater than high ametropias. The main reason for this effect is the scattered light inside the eye, the phenomenon that affects the electromagnetic wave when it encounters an obstacle or non-homogeneity. Visual perception is severely influenced in this process, because scattered light creates a veil of luminance that worsens the quality of the image. The Light Scatter Test, developed by City University of London, used here is non-invasive and it helps to understand the risks and the visual impairment caused by glare. This work allowed us to show how the age factor has a crucial influence on the amount of scattered light. The test proved to be reliable, confirming the expected data and showing the need for further studies to spread greater awareness of these issues within the scientific community and society, as well as being the basis for further developments in the scientific, medical and technological fields.
