something else to consider ....... and you will need an eye specialist to confirm. I have had problems several times with the build up of pollutants on my eyes. the pollutants I have trouble with is normal emissions ( car exhaust and industry pollutants). our eyes can accept certain levels and still clear them.... as soon as we get more pollution than we can handle, the excess accumulates and can be pulled away by our eye lids, as a "gunk". I have needed medical intervention on several occasions. something as little as walking on a different route, can change the levels of pollution you are subject to. an eye specialist can tell you how well you are removing the pollution we all are subjected to.
When you're stressed, You eat Ice cream, Cake, Chocolate & Sweets. Why? Because stressed spelled backwards is DESSERTS.
