The central region is the nucleus. Surrounding it is the cortex or cortical region. Look out for these symptoms:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">The cortex begins to experience opaqueness.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">The opacities begin from the periphery.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">They move towards the center or nucleus.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Their appearance could be wedge-shaped, or akin to white streaks (cortical spokes).<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">There is a gradual blurring of vision.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Glaring lights bother you at night.
