Led lights are mostly used nowadays everywhere, in homes, offices, and shops. They are useful and efficient as they consume low power and glow more than previous incandescent bulbs, but here we will know how led lights affects on the human body and what are harmful diseases caused by them.

Effects of LED light on the eyes:

The light-emitting diode is the device that emits rays when current flows through them. LED lights are efficient in both energies as well as in case of price. in this article, I will discuss how led lights affects on the human body especially eyes LED lights are emitting blue light that causes severe damage to our eyes. LEDs were emitting high energy blue lights having short wavelengths that are the cause of significant issues to eyes like fatigue, dry eyes.

The blue lights are not new for us; it is coming from the sun and also present in old yellow bulbs emitting a small amount. Close and continuous exposure from our mobiles tablets computer to LED blue light, although it has a minimal amount as compared to fluorescent LED lights but causes irreparable damage to eyes. Computers, tablets, mobile phones have these LED lights, and our enthusiasm for using these lights is increasing day by day, and in return, our eyes have to pay for that.

Diseases caused by LED lights affects:

According to American studies, affected the ratio of LED light to eyes in evening and night is more significant as compared today. Retina mostly affected by LED, which is light-detecting nerve tissue at the back of the eye and a considerable portion of the eye. They cause irreparable loss to the retina and also decreases the sharpness of our eyes.

Sánchez-Ramos said.

“Eyes are not designed to look directly at the light — they are designed to see with light,”

Following are the diseases

  • Macular degeneration
  • Cataract
  • Dry eyes
  • Tiredness or eyestrain

Macular degeneration:

Continuous exposure to LED lights quickens the maturing of retinal tissue, causing a decrease in visual sharpness and specific degenerative ailments, for example, age-related macular degeneration. As we all know, Macular degeneration is the severe irreversible vision disease of an older adult over age 60, but continuous exposure destroys the retinal layer called Macula.


LED lights are also responsible for cataract disease. Water and proteins are the major constituents of the eye lens. Proteins are arranged in layers, but with age, these proteins layers form clusters due to which cloud-like formation is created on eyes. It is the primary cause of blindness in the world. A person having no interaction with LED light might have cataract disease after the age of 40, but the person using LED lights with continuous exposure will have this disease before 40. Because blue lights LED, have short wavelength but high energy due to which this energy cause disruption in the protein layer and form clumps or clusters.  

Dry eyes:

Dry eyes are the condition of eyes when they are not ready to leave a “tear film” that washes and alleviates the eye each time they blink. The sight at that point gets irritated and dry. This irritation and dryness brought about by dry eye cause vision problems. In rare cases, dry eye can become a severe problem if not consider and treated well. Side effects of eye fatigue incorporate sore or disturbed eyes and trouble focusing.

Tiredness or eye strain:

The tiredness of eyes is also a significant problem, also known as eyestrain. Probably the most common cause is little sleep, sensitive eyes having allergy problems in the past, using a computer for a long time, poor lighting conditions, or have the light of high intensity, driving a vehicle for delayed timeframes, or studying for a longer time.

Every one who mostly spent time before led lights should take some precautions, here I am placing a health care link you can go there to learn about safety measures.
