What is Blue Light?
It’s one of the shades in the spectrum of visible light. Other colors include:
They are often referred to as VIBGYOR. Together, they produce the white light that is visible in the sunlight. Both LED and fluorescent (light-emitting diode) light bulbs also emit blue light.
Every color of the spectrum of visible light has a distinct wavelength and energy degree. The blue spectrum has shorter wavelengths and has more energy than other shades. Certain studies show a link between eye damaged by blue light and short-waves that has wavelengths between 415 and 455 nanometers. The majority of light coming that comes from LEDs in TVs, smartphones and tablets has wavelengths ranging from 400 to 490 nanometers.
What is the effect of Blue Light Affect the Eyes?
The majority of visible blue light is absorbed by the lens and cornea before it is absorbed by the retina. The light could affect the vision and cause premature aging of the eyes. Some of the best eye specialists in Delhi suggests that excessive exposure to blue lights can result in:
Eye strain: Blue light from computer screens and digital devices could reduce contrast, causing digital eyestrain. Dry eyes, fatigue poor lighting, or how you sit front of your computer may cause eye strain. The signs of straining eyes include sore or irritated eyes as well as trouble in focusing.
Damage to the retina: Studies suggest that continuous exposure to blue-colored light for a long time can result in damaged retinal cells. This could cause vision issues such as macular degeneration due to age or even make anyone blind.
Blue Light and Sleep
The amount of time you spend in front of screens, especially at night, can be linked to sleep issues. The blue light that comes from electronic devices disrupts your circadian rhythm, also known as your sleep cycle. The brain is notified to get up, while it is supposed to wind down.

Blue light exposure at night has been linked to depression as per some of the top neurologists in Delhi. However, exposure to blue-colored light throughout the day could result in the opposite. It’s been utilized for treating seasonal affective disorder also known as SAD. This is a form of depression that’s linked to the change of seasons. Research has shown that 20 minutes of exposure to blue light early in the day can alleviate SAD symptoms.
Advantages in blue light on the human body
Blue light exposure can provide numerous health advantages. It could:
- Help you stay alert: Studies have proven how exposure to light blue could increase your reaction speed and boost alertness when you’re not at your highest performance during the day.
- Improve memory and improve cognitive function: A study of participants in 2017 that had 30 minutes of blue light “washout” period showed better results in memory and verbal consolidation tests afterward. Participants in the study who experienced the amber-colored light “washout” did not perform as well.
- It could help improve seasonal depression.: Blue light therapy is currently one of the most popular treatments for treating depression. Researchers have discovered that it’s also a successful treatment for depression that’s not seasonal, particularly when it’s combined with antidepressant medication.
- Improve your acne: Numerous studies have demonstrated the blue-light spectrum kills bacteria that cause acne and decreases inflammation associated with acne breakouts. A word of caution When you decide to test at-home blue light devices, ensure that you select one that is that has been approved through FDA. Food and Drug Administration (FDA).
- Help clear some skin conditions: Actinic plaque psoriasis and keratosis are both treated with treatment with blue light therapy. Blue light therapy is also beneficial in treating basal cell cancer tumors
What can you do to protect your eyes from the damage by Blue Light, suggests the top eye doctor in Delhi?
Do some practice with the 20/20/20 strategy: When you’re using a gadget that emits blue light take a break every 20 minutes to look at objects within 20 feet of you. Take a look at the things for 20 second prior to when returning to your close view.
Keep your eyes moist: Eye drops, like artificial tears, as well as room humidifiers are great methods to prevent your eyes from getting too dry and inflamed when you’re using blue-light emitting devices.
Wear eyeglasses that meet the correct prescription: Looking at screens for extended time frames isn’t good for the eye health. If you’re wearing glasses prescribed by a doctor to improve your vision ensure that you’re wearing a prescription that is designed for how far your eyes are from the screen, which is usually an at least an arm’s length. Many glasses are designed to accommodate larger distances.
Make sure which type of light is turned on your screen: To lessen the chance of straining your eyes as well as sleep disruption, you might be able to set your screen to an “night shift” setting that has warmer tones. You can also buy blue-light-filtering screens that can be slipped over your computer’s screen when working in the dark. The filter will cut reflection away from the screen. Research has shown that they block between 30 and 60% of blue light. However, it’s unclear if blocking blue light can aid in preserving the sleep-wake-up cycle for those who are using screen backlights prior to bedtime.
