Don’t let your eyes become the scariest thing about Halloween

According to recently updated data released by Roy Morgan, more than one in five Aussies are embracing the spooky season this year by choosing to celebrate Halloween on the last day of October.

With more than $165 million expected to be injected into the national economy from the purchase of costumes and accompanying accessories alone, optometrists are warning those wanting to elevate their fright factor by wearing coloured or novelty contact lenses to consider the serious consequences improper use can have on eye health.

“Novelty contact lenses, also known as decorative or cosmetic lenses, are designed to change the appearance of your eyes. They come in various colours, patterns and effects, such as glowing eyes, cat-eye pupils or even black-out lenses. While these lenses may help take your Trick-or-Treat look from meek to eeek, the toll they can take on the eyes is scary stuff indeed,” said Katherine Whittaker, optometrist and National Professional Services Advisor at Optometry Australia.

In fact, a study published in the American Journal of Ophthalmology found that coloured or decorative lens wearers were at a much higher risk of developing eye complications, partly because of poorer lens quality and partly due to the lack of education on hygiene and safe wear practice.

“One of the biggest concerns surrounding novelty contact lenses is the lack of proper regulation; in Australia, contact lenses are classified as medical devices and should only be dispensed by a licensed optometrist. However, many people purchase these lenses online or from costume stores, where safety standards may not be met. This poses significant risks to eye health.”

Some of these dangers include:

Poorly made or contaminated lenses can introduce bacteria or fungi into your eye, leading to serious infections like keratitis (inflammation of the cornea). If left untreated, these infections can cause permanent vision loss

Improperly fitting lenses can scratch the surface of your eye (the cornea) and cause abrasions. This not only causes pain but also increases your risk of infection

Contact lenses that are not made from breathable materials can reduce the amount of oxygen that reaches your cornea. This can lead to corneal swelling, discomfort and long-term eye health problems

The dyes and chemicals used in novelty lenses may cause allergic reactions, leading to red, irritated, and watery eyes

If the lenses are not properly fitted, they can shift around your eye, causing blurry or obstructed vision. In some cases, they can also increase your sensitivity to light

However, if you’re set on using novelty contacts to complete your Halloween look, Whittaker shares some steps you can take to minimise the eye health hazards.

“First, always get a prescription—even if you don’t need vision correction—so that the lenses are properly fitted. It’s crucial to buy from reputable, licensed retailers to ensure safety. Practice good hygiene by washing your hands before handling lenses and never use tap water or saliva for cleaning.

Remember, never share lenses with others and avoid wearing them for extended periods as this can reduce oxygen supply to your eyes. If you notice any redness, pain or blurry vision, remove the lenses immediately and see your optometrist for advice.”

By visiting an optometrist, purchasing from reputable sources and following proper hygiene practices, Australians can avoid a temporary costume accessory turning into a permanent problem for their eyes this Halloween.
