Basic Visual Function and Visual Attention …show more content…
The visual acuity for babies is approximately 20/400, which develops with growth. The contrast sensitivity is reduced in infants compared to adults but tends to develop upon gaining visual experience. Contrast sensitivity shows the ability to differentiate luminance in two adjacent areas, for instance, stripes on a grating. Color vision, on the other hand, develops to near adult perceptual ability after four months of birth. The ability of infants to react to motion velocities differs depending on the type of motion observed or the age of the baby. Depth perception in infants seems to develop within the first few months as they become sensitive to motion-carried information for distance. After four months, babies can perceive depth through differences in optical
