Facts about tears 1. Tears have layers, the inner layer has some mucous to help our tears stick to the eye, the outer layer is oily to prevent evaporation. 2. Tears flow, they are produced in the lacrimal gland above the outer corner of the eye, and they drain through a tiny opening in the inner corner of the eye called the punctum. Tears drain to the nasal cavity, which is why your nose runs when you cry. 3. Tears are necessary, they lubricate the eye and flush away debris, but they also deliver oxygen and nutrients around the eye and remove waste products. Tears are also the first line of defence for the eye against infection. 4. There are different types of tears, normal or basal tears, reflex tears to flush away an irritant, and emotional tears. 5. Are your eyes dry? Dry eye is very common, and can make your eyes red, gritty, tired, sore, and paradoxically, watery. Fortunately, there are a range of ways to manage this, starting with occasional use lubricating drops. Due for an eye exam? Used your health fund rebate for the year?
