Causes and Symptoms of Blurry Vision
When it comes to angle-closure glaucoma, the loss of vision is not typically characterized by complete darkness. Instead, individuals often perceive their vision as cloudy or blurry. While some may still be able to see relatively normally, their sight is hindered by the blurriness. The progression of blurry vision can vary depending on how quickly the glaucoma develops. In some cases, the transition to blurred vision is gradual, occurring over time. However, there are instances where symptoms manifest rapidly and suddenly. In such situations, vision can deteriorate within a matter of minutes, causing significant impairment.
Sudden Visual Disturbance
When it comes to glaucoma, many individuals may encounter sudden visual disturbances, a phenomenon commonly observed among people with migraines. These disturbances are often referred to as photopsia, characterized by the perception of bright flashes of light resembling that of a camera flash. Another type of disturbance known as metamorphopsia can also occur, causing visual images to appear distorted in terms of size, color, or shape. This distortion can make linear objects such as grids or lines appear curvy. Additionally, blind spots near the center of the field of vision are common among individuals with glaucoma. These blind spots may gradually move across the visual field over time.
