How to Install Visual Differ on Windows

Light scattering is a phenomenon that occurs when localized irregularities in the refractive index of the ocular media cause light to spread at larger angles over the retina. This can affect the retinal image, even if the optical quality is only considered in terms of aberrations. The homogeneity of the ocular structures plays a crucial role in shaping the retinal image.

When projecting a point source onto the retina, the ocular point spread function (PSF) is affected by diffraction in the pupil, aberrations, and scatter. Wavefront sensors can provide information on the overall optical quality of the eye through its aberrations.

To study the eye's optical quality, it's essential to analyze both the geometrical characteristics of the ocular surfaces and the intrinsic properties of the media that light interacts with when passing through the eye. The optical quality of the retinal image is a key factor influencing visual performance.

In order to accurately measure the effect of intraocular scattering, a new method has been developed that involves projecting disks of uniform radiance onto the retina, recording the images after reflection and double pass through the eye's optics, and analyzing the images properly. This technique allows for the accurate reconstruction of the wide-angle PSF in the living human eye up to 8 degrees.

However, the more peripheral areas of the PSF have been investigated only psychophysically, and the impact of its spatial characteristics on retinal image quality and visual function has not been extensively documented. There are various optical methods for measuring the central part of the PSF, but a new method is needed to accurately measure the peripheral zones associated with light scattering.
