When you experience vision changes, it can involve vision loss or vision distortion. Most people describe both types of changes when vision becomes blurry. People who have normal vision have a complete balance of both the rods and the cones in the eyes. If a person is perhaps missing or has damaged cones, they most likely have reduced visual perception during the day and at night.
Vision distortion is an inability to see clearly and correctly. This distortion can cause poor focus due to refractive error, lack of depth perception, double vision, glare or halos, light flashes, or floaters. It could also involve color blindness. If you are also affected by the use of Elmiron and want an San Diego Elmiron Eye Legal Help, you can search for it online.
Refractive error is a failure of the eye to properly focus an image on the retina. Makes images blurry. Depth perception is when you have the ability to determine the complete position of objects in that area. People with poor depth perception may have a hard time distinguishing which of the two objects is closer and their actual position.
Some people experience something like glare and halos around bright lights, especially when driving at night. These symptoms are more common in the elderly and in those who have undergone certain types of refractive surgery or who have certain types of cataracts. Reflections and halos can also occur in people whose pupils are very dilated.
Vision loss is a total or almost total lack of sight. People with vision loss may see nothing at all, or they can distinguish light from darkness and can even detect fuzzy shapes. Vision loss can encompass part or all of the visual field of one or both eyes and can be unexpected or constant, temporary or permanent. Vision loss is something that people usually notice right away. However, gradual loss of vision may not be noticed or discovered over a period of time, it may not be noticed until a car accident or other events that may occur and require a comprehensive eye exam.
