Summary Introduction

To review:

The cause of blindness of premature babies who were born before 25 weeks after conception.

Introduction:

The outermost covering of the eye is known as sclera and the cornea. The cornea forms a dome-shaped structure at the front side of the eye. The inner layer of the eye is the retina that includes rod and cone photoreceptor cells. These cells provide vision at different intensities of light. Various types of disorders are associated with vision and some of them are related to age while others are related to other reasons. Some of the common disorders that are associated with visualization are cataract, glaucoma, and some other conditions that are associated with accommodation.

Research suggests that newborns are able to discriminate their own language from a foreign language, and their mother's voice from a stranger's voice. In contrast, their visual abilities are much less developed at birth, and develop rapidly over the first few months of life. One explanation for this is: A) Fetuses get equivalent auditory and visual experience before birth, but before they are born they are only able to learn from auditory experience B) Fetuses do not experience sensory information before birth (i.e., they cannot hear, see, smell, etc.) but language develops faster than vision because it is more evolutionarily important C) Fetuses get equivalent auditory and visual experience before birth, but vision requires additional postnatal triggers to be fully activated D) Fetuses can hear many types of sounds prenatally but have limited visual experience until after birth.
You are watching the stars at night, and you never seem to be looking at the right spot to catch the brightest meteors. Which of the following might explain this? a)Your fovea contains mostly cones; thus you see dim light especially well when looking right at it. b)Your peripheral retina contains more rods, which are more sensitive to dim light than cones; thus objects in your peripheral vision appear brighter in dim light situations. c)Detection of light depends mostly on its color rather than intensity; thus cones play a larger role in detection of light in dim light situations. d) all of the above.     ( well explain  the correct  answer  and type answer).
Which of the following is true about infants’ visual acuity? a. Poor visual acuity early in life allows key features of the visual world to “pop out”  b.Before 3 months, infants are not able to make sense of their visual world c.It’s not possible to test visual acuity before infants are 6 months d.Newborns have poor visual acuity, but excellent colour vision
