The Role of Tears

The Role of Tears

We cry for all kinds of reasons: a stubbed toe, a particularly poignant scene in a movie, freshly cut onions the list goes on. Would it surprise you to learn that, chemically, not all tears are the same? Or how about that even though we usually do it when we’re upset, crying is in fact good for us?

Tears and Basic Eye Protection

Even when we aren’t crying, our eyes are covered in a protective film of basal tears, which is composed of three layers: the mucous layer right up against the cornea, the middle aqueous layer that is mostly saltwater, and the outer lipid layer that seals everything in and reduces evaporation.

This tear film is essentially an all-in-one lubrication, cleaning, and disinfecting system for the surface of our eyes. It washes dust, debris and other particles out of our eyes with every blink and keeps our eyes comfortable and vision clear.

Our lacrimal glands in our eyelids are constantly producing small amounts of basal tears to replenish the tear film. The reason our eyes don’t leak with used basal tears all day is that what doesn’t evaporate drains out through the lacrimal ducts on the inner corners of our eyes and down into our noses. That’s why our noses get runny when we cry!

Having A Good Cry

Basal tears are present all the time in healthy eyes, but when we cry and the tears overflow, they come in two different types: reflex and emotional tears. Even though crying can be embarrassing and messy at times, both types of tears are actually good for us.

Reflex Tears

Reflex tears are essentially the same as basal tears, but when our eyes get irritated, basal tear production goes into overdrive to safely flush out whatever caused the problem. That’s why we tear up when we’re chopping onions or get something in our eyes.

Emotional Tears

Most of us know what it’s like to cry and come out the other side of it feeling somehow refreshed and more optimistic about life, even when nothing about the situation that made us cry has changed. That’s because emotional tears actually clear out chemicals that build up in times of stress. Crying doesn’t just release pent-up emotion, it also purges harmful chemicals and triggers pain-regulating hormones! No wonder we feel better afterward!

Let’s Keep the Tears Flowing

Basal tears are essential for the health of our eyes, which is why dry eye can be such a serious issue. As we age, basal tear production goes down and dry eye becomes a more common problem. Dry eye can cause significant discomfort, blurred vision, and even vision loss. Make an appointment to see Michael if you’re noticing any discomfort, or have any visual concerns.

Have you heard that eating carrots will give you great night vision?


That’s actually a leftover idea from World War 2. The British didn’t want enemy soldiers to learn about their new radar technology, so they claimed their airmen got their night vision by eating carrots! Whether or not the Germans fell for it, the idea stuck around. So, is there any truth to it? Maybe not to the part about superior night vision, but carrots and other foods like the ones below do contain nutrients that help our eyes stay healthy!


Sweet Potatoes and Oranges

Two important antioxidants that help us stay healthy are vitamins C and E. Vitamin C can lower our risk of developing cataracts and may even slow down the progression of age-related macular degeneration. The easiest way to get vitamin C is by eating plenty of citrus fruit, such as oranges, grapefruits, and lemons. Vitamin E protects our eyes from “free radicals,” molecules that disrupt healthy tissue, and you can get it by eating sweet potatoes and nuts!


Fish are the best source of omega-3 fatty acids, which are crucial for brain function and a healthy immune system, but it helps to protect against cataracts, dry eye syndrome and even macular degeneration. One study found that people who ate just one weekly serving of fish, generally a good source of omega-3 fats, cut their risk of macular degeneration by over 30 percent!

Eggs and Leafy Greens

Studies have shown that the nutrients lutein and zeaxanthin are linked to a lowered risk of chronic eye diseases like cataracts and age-related macular degeneration, and the foods that have the most of these are eggs and leafy greens!


Carrots, along with other yellow, orange, or leafy green fruits and veggies, is an excellent source of vitamin A. These types of produce get their colour from beta-carotene. Our intestines use beta-carotene to make vitamin A, which helps our eyes convert light into brainwaves and is an important component of our corneas (the clear part of the front of our eyes). Vitamin A deficiency leaves up to half a million children blind each year!


Oysters are a great source of zinc. Why do we need zinc? It’s essential to many processes in our bodies, including helping vitamin A get from our livers to our retinas. It doesn’t matter how much vitamin A we eat if it can’t get to where it needs to go! If you’re not a fan of oysters, you can get your zinc in smaller doses from meats, beans, and nuts.

Another Component of Eye Health Is Eye Exams!

Your eyes are sure to benefit when you add more of these nutritious foods to your diet, but even the healthiest food isn’t a substitute for a regular eye examination! Poor nutrition isn’t the only thing that can cause eye problems, which is why it’s crucial to schedule appointment with Dr Michael Jackson at Main Beach Optical, especially if you’ve noticed any changes in your vision.

Hay fever and your eyes

Hay fever is the most common form of allergy which affects two in five Australians throughout the Spring and Summer seasons. Mainly affecting the eyes and nose, typical symptoms include sneezing, itchy ears, nose, eyes and throat, a runny or stuffy nose and red, watery eyes.

How symptoms can be relieved

  • Try to identify what triggers your hay fever and avoid these as much as possible
  • Keep windows closed during the pollen season
  • Splash eyes with cold water at regular intervals to flush out pollen
  • Make use of air conditioning and/or air filtering systems in your house and car
  • Anti-histamine medications help control sneezing and itching and assist in soothing the eyes from irritation
  • Eye-drops relieve itchy, swollen or watery eyes
  • Nasal sprays help reduce the inflammation in the nose which is the cause of nasal blockage and other symptoms.

Hay fever and contact lenses

If you suffer from hay fever and are a contact lens wearer, you may not be very comfortable wearing them during hay fever season. Useful tips include:

  • Avoid wearing contact lenses when outside conditions are hot, dry and dusty during hay fever season, or when mowing the lawn
  • Wearing sunglasses in addition to contact lenses may help protect your eyes from dust and pollen circulating in the air
  • When the pollen count is very high, switch to wearing glasses rather than contact lenses to avoid irritation
  • Consider using daily contact lenses; replacing them daily reduces the chance of protein build up that can lead to sore, irritated eyes

Although hay fever can have a large effect on your day to day life, there is relief available. Taking simple precautions and utilising products available on the market to assist with hay fever symptoms can help limit your discomfort and help you enjoy the most out of every day.
