Vision changes and problems can be caused by many different conditions. Presbyopia -- difficulty focusing on objects that are close. This problem often becomes noticeable in your early to mid 40s. Cataracts -- cloudiness over the eye lens, causing poor nighttime vision, halos around lights, and sensitivity to glare. Cataracts are common in the elderly. Glaucoma -- increased pressure in the eye, which is most often painless. Vision will be normal at first, but over time you can develop poor night vision, blind spots, and loss of vision to either side. Glaucoma can also happen suddenly, which is a medical emergency. Diabetic eye disease.
The normal blood glucose level (tested while fasting) for non-diabetics, should be between 3.9 and 5.5 mmol/L (70 to 100 mg/dL). The mean normal blood glucose level in humans is about 5.5 mmol/L (100 mg/dL); however, this level fluctuates throughout the day.he normal blood glucose level (tested while fasting) for non-diabetics, should be between 3.9 and 5.5 mmol/L (70 to 100 mg/dL).

Your Blood Sugar Count A blood sugar count over 1000 is way beyond healthy, normal levels, even for a diabetic. Normal blood glucose levels are within a range of 70 to 100. A consistent reading over 125 may be indicative of diabetes. Levels as high as 200 to 500, let alone 1000, can pose a serious risk to the body. A blood sugar count shows the level of glucose in the blood. It is important to try and keep levels as normal as possible, especially for diabetics.
