transduction
The presence of all-trans-retinal is essential for the process of vision in the human eye. It is a form of vitamin A that is converted into a molecule called rhodopsin in the retina. Rhodopsin is a light-sensitive protein that helps in detecting light and initiating the signal for vision. When light enters the eye, it triggers a series of reactions that involve all-trans-retinal, leading to the perception of images.
The near point of vision increases with age because the elesticity of the lens decreases as we get older.near pointthe nearest point of clear vision, the absolute near p. being that for either eye alone with accommodation relaxed, and the relative near p. that for both eyes with the employment of accommodation
No, the color of your iris does not affect your vision. The iris is responsible for controlling the size of the pupil, which regulates the amount of light entering the eye. Vision is primarily determined by the shape of the eye and the health of the cornea, lens, and retina.
This is quoted from another question:"Having 20/60 means that you need to be 20 feet away from an object rather than a "normal" person who can see that object at 60 feet."http://wiki.answers.com/Q/Is_20-60_vision_considered_bad
A prism in front of one eye will change apparent position of an object you're looking at. It will shift your visual field, but not widen it or "improve" it. A prism used with both eyes open would most likely cause double vision or the muscles around the eye would adjust to negate it's affect entirely. Prisms are generally used to shift the apparent location of an image in one eye so that both eyes can pay attention to the that same object at once, giving binocular single vision. If both eyes are not looking at the same object/point in space, then it will usually result in seeing two different images/double vision/diplopia.
Light energy is used in our vision. When light enters the eye and strikes the retina, it is converted into electrical signals that are sent to the brain for processing, allowing us to see.
For you to see an object, it needs to reflect or emit light towards your eyes. Light bounces off the object and enters your eyes, where it is interpreted by your brain as vision.
Association area of the cerebral cortex
Vision is not any type of energy. Vision can detect the visible range of the electromagnetic spectrum by the interaction of electromagnetic waves with chemical compounds; this interaction then results in electrical impulses being sent to the brain.

Direct vision is your central vision. It refers to how and what you see when looking straight at an object. Indirect vision refers to your peripheral vision, which means the things you see "out of the corner of your eye" or off to the side while you are looking directly ahead.

I am pretty sure it is the retina.The retina not only is used for focusing but also The sides of the ''retina'' are responsible for our peripheral vision. The center area, called the macula, is ''used'' for our fine central vision and color vision. Are you referring to optical nerve impulses?
The science term for sight is vision. Vision is the process through which light is detected by the eyes and converted into signals that are interpreted by the brain to form images.

The cerebral cortex is responsible for interpreting impulses from the senses. Different areas of the cortex are specialized for processing information from different sensory modalities, such as vision, hearing, touch, taste, and smell.
Your front vision is the best because around the center of the retina (except for the blind spot where the optic nerve enters) is where most of the vision receptors are. You don't have as many receptors on the areas corresponding to your peripheral vision.
