Eye problems are common in old age, but with an increased usage of electronic devices like cell phones, tablets and notebook computers, which we essentially interact with by staring at their screens all day long, exposure of eyes to blue light has increased dramatically. Such exposure is detrimental and can lead to early onset of eye problems and other health concerns.

Blue light is a type of light that can be seen by the human eye (known as visible light), and is among the visible light spectrum that our eyes are sensitive to. Blue light helps to provide basic illumination so that we can see, as well as increase positive feelings. However, blue light increases the risk of developing age-related macular degeneration, largely by causing oxidative damage. Age-related macular degeneration is a major cause of significant vision loss in old age.

There is a pigment in the back of the eye that offers some protection against blue light. But the protective mechanism only lasts a short period, and during daylight hours. Furthermore, blue light is not only found through your monitors, but also artificial light sources such as fluorescent light bulbs and LED lights.

Protecting oneself from blue light

One of the most obvious solutions to limit exposure to blue light is of course, to refrain from using your digital devices at night, and to sleep with the lights turned off.

Do also take periodic breaks from staring at the screen, preferably every 30 minutes.

More companies are releasing screen protectors claiming to filter out the blue light. It would be a good idea to buy them for your gadgets, but make sure you purchase them from reputable companies.

Consider getting glasses with melanin pigmented polarized lens which will also help protect against blue light. Ask your optician about BluTech lenses, that, unlike the aforementioned, filter out blue light without impacting your colour perception.

Get regular eye checkups from an optometrist if you are at risk of developing macular degeneration, especially after you hit 35 years old, when early onset of macular degeneration is known to occur. Such people include those who have had cataract surgery, or have a family history that suggests increased risk of it. Age 50 and above is when the disease starts to show.

We only have one pair of eyes, and macular degeneration is an irreversible problem. Take good care of your peepers, so that even in your old age when mobility may no longer be as good as before, you may still continue to enjoy the world through your windows.
