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.
It doesn't matter where the bruise is. It all depends on how bad the bruise is. Not even a professional doctor could tell you how long it will take. Just be gentle with it and it will heal faster.'m looking at a few weeks to recovery. The more severe the injury the longer it will take-up to a few months. I'm on day 3 right now and I have yet to see any reduction in the pain levels without medication.
