How does the weather affect my eyes?

by Bella Xiao on January 07, 2019

With the colder seasons in full swing, it's more important than ever to look after your health, and that includes your eye health. Cold, freezing temperatures are more likely to bring about illnesses - such as cold and flu - than the summer months, which means you must wrap up warm to fight the chill.

While you can simply layer up with knitwear, including hats, scarves and gloves, there's another part of your body that is more difficult to protect from the harsh weather conditions - your eyes.


Since your eyes are a delicate part of your body, they are highly susceptible to becoming affected by the wintry temperatures. You should, therefore, be aware of the warning signs and ensure you take extra care to look after your eyes this season. Here are a few things to look out for and what you can do if you experience them:


Dry eyes

In cold and extreme weather, the strong winds can cause your eyes to lose their natural moisture and become dry. This will leave them feeling sore and, subsequently, lead to feelings of pain and discomfort.

Not just this, but since you are more likely to keep the windows inside your home closed to shut out the cold weather, and turn your heating on, the increased humidity levels can also cause dry eyes.

In order to combat this, there a few things you can do. Firstly, stay hydrated by drinking plenty of water and increase your intake of omega-3 fish oil, which can help stimulate tear production. You can also buy a humidifier to keep moisture in the air inside your home.

Lenses such as 1 Day Acuvue Moist have a moisturising effect on your eyes, helping to reduce and minimise the symptoms of dry eyes throughout the day. For increased moisture, consider silicone hydrogel contact lenses such as comfi Pure 1 Day daily disposable lenses, which offer both exceptional clarity and all day hydration.

You can also use hydrating eye drops such as comfi Drops to keep your eye hydrated and to tackle the daily burnout of computer eye strain, which can intensify in the winter months.

Burning eyes

In very extreme weather conditions, you’ll find that it can be difficult to fully open your eyes. Attempting to force your eyes open can actually cause the cornea to freeze, which is highly painful and can lead to issues such as light sensitivityblurry vision and eyelid spasms.

You may think that you only need to wear sunglasses in the summer; but in fact, wearing sunglasses with UV protection in winter can protect your eyes from harsh winds and bright light. Reflective rays are a potential issue during the winter due to snow and can contribute to eye health issues such as cataracts and snow blindness.


Excessive tearing

While some people experience dry eyes from strong winds and the cold weather, others suffer from excessive tearing, with their eyes becoming extremely watery in the winter weather.

This can be highly frustrating, especially when the tears cause your vision to become blurry. In order to prevent excessive tearing, wear a pair of sunglasses, and make sure you wipe any tears away with a clean, soft cloth to avoid germs spreading and entering your eyes. Eyelid wipes such as Clinitas Soothe WipesSystane Lid Wipes and Biotrue Daily Eyelid Wipes.will help clear your eyes and can fit conveniently into your bag, purse or pocket.

Red swollen eyes

Eyes can become red and swollen in cold weather. This is due to constricted blood vessels in the tissues around the eyes, while sore, swollen eyes can lead to blurry vision, excessive tearing and eyelid spasms.


Make sure you protect your eyes in cold and bright weather by wearing a pair of UV-protected sunglasses. You can also give your eyes a DIY spa-like treatment with the Thera-Pearl Eye Mask. The handy mask can be used either hot or cold, depending on your preference, and will help to relieve tired, irritated and swollen eyes.


Don't forget to make regular visits to your opticians for a general check-up on your eye health.
