differs from common visual acuity testing in a routine eye exam‚ which measures your ability to recognize smaller and smaller letters on a standard eye chart. Contrast sensitivity is a very important measure of visual function‚ especially in situations of low light‚ fog or glare‚ when the contrast between objects and their background often is reduced.

Case Report Clinical Assessment of a Patient With Compound Myopic Astigmatism and Convergence Insufficiency Abstract Myopic astigmatism is a specific type of astigmatism wherein the light focuses before it reaches the retina. This condition is classified as a combination of astigmatism and myopia‚ or nearsightedness. If both principal meridians are nearsighted‚ but one is more pronounced than the other‚ it is considered to be a compound myopic astigmatism. Convergence Insufficiency on

As we age or incur visual impairment‚ we may need brighter light when reading. Explain why this is the case. The reason a person may need brighter light when they get older is because of a condition called presbyopia (old eye). When a person is 20 years old their near point

Think about what would happen to your vision if specific tracts were cut along the path from the retina to the occipital lobe. What visual deficits would you experience if you cut the tract at the right or left optic nerve‚ optic chasm‚ or lateral axons extending from the occipital lobe? The optic nerve carries information from the retina to the occipital lobe of the brain‚ where
