Verified step by step guidance

1. Understand the concept of depth perception: Depth perception is the visual ability to perceive the world in three dimensions (3D) and to judge the distance of objects.
2. Evaluate the first statement: 'It is the ability to see in two dimensions.' This is incorrect because depth perception involves perceiving three dimensions, not two.
3. Consider the second statement: 'It is almost always present in people who were blind from birth and later had their sight restored.' This is generally false, as individuals who gain sight later in life often struggle with depth perception due to lack of visual experience during critical developmental periods.
4. Analyze the third statement: 'It helps one to judge how far away objects are.' This is true, as depth perception allows individuals to estimate the distance and spatial relationship between objects.
5. Review the fourth statement: 'It does not develop until the toddler years.' This is incorrect because depth perception begins to develop in infancy, although it continues to refine as the child grows.
