Do our eyes really need UV protection?

In short- YES! 

Summertime calls for long hours in the sun, and while most of us remember our hats and sunscreen, we may sometimes forget that our eyes need SPF too. 

Just like the rest of our body, there are a plethora of ocular changes that are caused or accelerated by UV exposure; some are mild and can be treated, others can potentially be sight-threatening. Furthermore, because UV damage is accumulated over your lifetime, it's crucial to start wearing proper eye protection at an early age to shield your eyes from years of ultraviolet exposure. 

How exactly does UV light harm your eyes?

UV radiation both from the sun, and from indoor artificial rays, can increase your risk and progression of certain ocular diseases, including:

Cataracts: when the crystalline lens inside your eye becomes cloudy over time. This little lens is supposed to be clear in order to let light pass through into the back of the eye, however the oxidative damage caused by UV exposure over an individual’s lifetime can cause this lens to become hazy, reducing visual resolution and quality (think about looking through a clear window, versus one that hasn’t been cleaned for a few years…!) 

Eye cancers: These can take years to develop, but UV radiation can cause growths around the eyelids, the surface of the eyes, as well as specific ocular structures inside the eye. Some of these growths may not affect vision and only cause structural changes, which make them difficult to notice in their early stages. 

Pterygium: this is a membrane growth on the front of the eye which can progress over time to cover part of the cornea, the clear front window of the eye. If a pterygium is advanced, this can result in distorted vision, an inflamed and irritated eye, and can grow back even once removed. 

Macular degeneration: Oxidative stress and damage to the tissues at the back of the eye can also contribute to macular degeneration, which is where changes occur to the central part of the eye (macula) responsible for central and detailed vision. Progression can be slow but very detrimental to vision and is irreversible. 

Protect your eyes from sun damage in every season 

Time to go shopping for some sunglasses! But keep in mind, the UV rating of the sunglasses is just as important as choosing ones that fit well (and look great). 

Before purchasing a pair, ensure that they have a UV protection value of 4 or 5 under the New Zealand/Australia Standard for sunglasses, as they provide coverage on almost all radiation. 

Additionally, follow these tips for greater sun protection:

• Supplement sunglass use with a wide brimmed hat 

• Select sunglasses which are larger and potentially have some wrap-around, which reduces peripheral exposure to rays 

• Wear sunglasses even when its cloudy or you're in the shade, as well as during cooler months 

• Avoid tanning beds, which can cause the same risks to your eyes and body as outdoor light can 

• Be extra vigilant in certain situations when UV radiation can reflect and cause more intense damage, e.g. snow, sand, water, and ice. 

But, remember that not all sun is bad - Spending time outdoors and getting some sunlight is essential and can have healthy effects for our general health and wellbeing. Just don’t forget those hats and sunglasses! 

By embracing these simple guidelines and tips, you and your family can stay safe in the sun all year long.
