As a youngster - and also maybe even as a grown-up - you could have been afraid of the dark. However should we be more afraid of light? e11 led lamp know UV light can be harming to our skin, and also recent studieshave shown that UV light and also specific wavelengths of blue light can also be damaging to our eyes - bring about vision loss.



The infographic below highlights the risks and also benefits of blue light as well as the damaging impacts of UV light on our eyes. We spoke with Kirk Smick, O.D., anoptometrist in Morrow, Ga., to figure out just how dangerous light influences our vision and also what we can do to shield our eyes.

Dr. Smick: While light is an important part of our day-to-days live - helping us see, controling our sleep/wake cycles, as well as even offering us with vitamin D - everyone needs to recognize that we are additionally exposed to unsafe light that can not only threaten to our skin yet also influence the long-term health of our eyes. We require day-to-day defense from the hazardous effects of both visible and also non-visible wavelengths of light, specifically UV light as well as specific wavelengths of high-energy blue light.



Throughout an eye exam, are there indications that reveal exposure to UV light?

Dr. Smick: Yes, several patients who invest a huge quantity of time working outdoors in the sun show indications of pterygium, a growth of fleshy tissue on the white of the eye that can extend over the cornea and disrupt vision. An additional indication of over-exposure to UV light is the growth of cataracts at a level more than normal for their age.

Why should we be concerned about blue light?

Dr. Smick: It's the high-energy Blue-Violet light that we have to bother with. Recent studies have actually shown that this wavelength oflight is a risk variable for retinal damages and age-related macular degeneration (AMD), which brings about central vision loss. As we integrate an increasing number of LED light into our environment, there is a greater requirement for security from high-energy source of lights.



Throughout an eye evaluation, can you tell if a patient spends a lot of time in front of a computer system all the time?

Dr. Smick: Many times patients' symptoms of worn out eyes and also frustrations at the end of the day are dead giveaways of prolonged computer usage. solar torch lights suffer red eyes, dryness, trouble focusing, and eyestrain.
