  • The cellular phone has become one of the easiest and fastest ways of communication
  • Too much exposure to blue light and UV light from the gadgets, especially cellular phones, can cause “Ultraviolet (UV) Keratitis”
  • Receiving too much blue light can damage the cornea of the retina of the eye

The cellular phone is one of the most useful of gadgets nowadays. Some couldn’t even live without their phones because it has been an everyday routine to check Facebook, shares photos on Instagram, and tweet messages on Twitter.

The use of cellular phones has become one of the easiest and fastest ways of communication, where we spend long hours using gadgets. But medical experts warn that having too much exposure to the gadget’s brightness level can lead to blindness.

Google says that blindness is the state or condition of being unable to see because of injury, disease, or congenital condition. Using gadgets, especially cellular phones, could harm our eyes.

Dr. Yul Dorotheo, a neuro-ophthalmologist, explains that too much exposure to blue light and UV light from the gadgets, especially cellular phones, can cause “Ultraviolet (UV) Keratitis,” an inflammation of the cornea. But this can be prevented by following his advice to adjust the brightness level of the cellular phone when you are in outdoor places.

Simply because the exposure of the bright light from your phone is reflecting directly to your eyes, plus sunlight from the sun can cause even much more UV light.

“When you’re outdoors, tumitingin ka sa phone mo hindi mo masyadong makita kasi maliwanag so you tend to put it on the brightest setting. Compounded ang exposure mo sa bright light, reflected sunlight plus sunlight,” said Dorotheo.

The intensity of receiving too much blue light can damage the cornea or retina of the eye.

“Intense use of the phone can give you intense exposure to blue light that can damage the cornea or retina,” he added.

Experiencing eye strain and headache are symptoms of having UV Keratitis and if it is not given proper treatment and continuing to do the old practice of using the cellular phone, it can worsen the injury that could damage the central vision which can lead to blindness.


There are individuals who were born blind and wishes to see the beautiful world so we, who are given the opportunity to see, must take care of our eye-sight.
