UV and blue light MAY cause serious damage to your eyes – do you know how to protect them properly?
When the sun is shining, most of us head outdoors in a keen attempt to enjoy the weather and soak up some rays. You are probably aware of the importance of wearing sunscreen to protect your skin, but did you know it’s just as crucial to protect your eyes too? UV radiation is always present. All year round, all day, in winter and summer in sunny and even overcast conditions. To protect our skin, we wear sunscreen, unfortunately we can't apply sunscreen to our eyes.
Sunlight is comprised of three types of UV rays – UVA, UVB and UVC. It is the first two – UVA and UVB – that can cause serious damage to your eyes, even when it’s cloudy. For this reason it is best to wear UV protection as often as possible whenever you’re outside, not just during your beach holiday!
In the short term, direct exposure to sunlight can cause a condition called photokeratitis – a kind of sunburn of the eyes. This is quite painful and can cause a gritty, burning sensation in your eyes, but is only temporary. Over a prolonged period of time, however, extended exposure to UV rays can contribute to the development of conditions like photo ageing and wrinkling of the skin around the eyes, macular degeneration, glaucoma and even cataracts. If problems like these are left untreated, there is a serious risk of permanent sight damage or even blindness.
Similarly, your eyes may also be damaged by excessive blue light (also referred to as High Energy Visible Light). Blue light is found naturally in the atmosphere, as part of the light spectrum. In small quantities it is necessary for health reasons and to regulate your sleep cycle. However, it is also found in much more concentrated amounts in various technological devices, including televisions, laptops, tablets, smartphones and most low energy lightbulbs including LED and compact fluorescent.
Our modern day lifestyles typically include the use of devices like these on a daily basis, and so the risk to our eyes from the damaging effects of blue light is ever-increasing. It is important to not only ensure that you moderate your uses of these appliances but also that you attend regular eye examinations so that we can check your eyes for any early signs of ocular damage.
