Keratoconus causes the middle of the cornea to thin, bulge outward, and form a rounded cone shape. This abnormal curvature of the cornea can cause double or blurred vision, nearsightedness, astigmatism, and increased sensitivity to light.
Bruises develop when small blood vessels under the skin tear or rupture, most often from a bump or fall. Blood leaks into tissues under the skin and causes the black-and-blue color. As bruises (contusions) heal, usually within 2 to 4 weeks, they often turn colors, including purplish black, reddish blue, or yellowish green. Sometimes the area of the bruise spreads down the body in the direction of gravity. A bruise on a leg usually will take longer to heal than a bruise on the face or arms.
Heal New Bruises Quickly. 1  1. Apply a cold compress, such as a cold washcloth, to the bruise for 1 to 2 days after the injury. Never apply ice directly to your skin; it could cause frostbite. 2  2. Avoid massaging the bruise or applying heat, which may cause it to worsen. 3  3. Elevate and rest the bruised area.  4. Take bromelain.
