Can short-sighted people use virtual reality without glasses? I asked an expert. This is something I was wondering after chatting to my friend Richard at the games festival EGX Rezzed. Iâve tried the Oculus Rift and the HTC Vive (writeup here), and was blown away by both â but I had my contact lenses in.
Kidney is the organ that is in charge of producing urine, so urine changes may imply kidney problem sometimes. Normal urine color ranges from pale yellow to deep amber, but sometimes we may notice our urine appears colorless, which makes people worried and wonder if it mean kidney failure.
Normal urine can range in color from pale yellow (almost colorless) to deep amber. Dark amber urine is usually very concentrated and means that you should be drinking more water. Foods, medications and even vitamins can change the color of urine temporarily but eliminating the cause brings the color back to normal.Most changes in urine color are harmless and the color will go back to normal within a day or two.rine with a bluish tint can mean some type of bacterial infection or may just mean that you have a high level of calcium. If this persists, give your health care professional a call. Brown urine can indicate a potentially serious condition and you should contact your doctor's office for help.
