How does blue light affect your vision?

Blue light is the last colour of the visible spectrum of sunlight that moves with damagingly high energy. Blue light is everywhere- the screens, the LEDs, the sun, all of them emit blue rays. This exposure of intense blue rays has made us all vulnerable to eye disorders and syndromes. You must have surely seen a lot of people wearing blue light glasses . If you have been wondering what blue light is, read on to know how blue light affects us and what are the preventive measures to avoid blue light damage.

Different ways in which blue light affects us

1. Cataract

The eye lens can absorb short blue waves from penetrating through the eye and damaging the light sensitive retina. However, during this process, it induces the production of substances and derivatives which get added to the lens tissues and turn it yellow.

2. Retinal damage

As the blue rays hit the retinal cells, a chain of toxic reactions is induced in the cell components. This damage gradually results in severe diseases like Age-Related Macular Degeneration. ARMD is the leading cause of blindness in the population of the UK.

3. Computer Eye Syndrome

Digital Eye Strain is an extremely prevalent problem among people who use laptops and smartphones for prolonged hours. While reading glasses are effective in blocking blue waves, it is better to limit screen time.

4. Insomnia

Studies reveal that blue light rays can alter the sleep cycle and make us insomniac. Exposure to blue rays during bedtime makes us more alert by suppressing the production of the sleep hormone, melatonin.

Measures to combat blue waves

· Blink more

When we stare on the tablet or laptop screen for long, we tend to blink very less, leaving our eyes too dry. Blinking helps to evenly spread the tears inside our eyes and thus lubricating them. Make a habit of blinking as often as you can, especially while watching screens.

· Adjust lightings

The brightness of your screen must not be too bright and too dim as compared to the brightness of the lights in your room. Major contrasts put extreme stress on the pupil and the lens of your eye. Try to sit in the most brightly lit area in your room.

blue light glasses

· Wear blue light glasses

Blue light blocking glasses are an effective tool to prevent blue rays from falling on the cornea and pass through the eye contents. You can ask if your optician can add an anti blue light coating on your lenses.

· Eat good food

Foods like oranges, carrots, blueberries, bell peppers, green vegetables and nuts are rich in Vitamin A, C and E. They also contain abundant amounts of antioxidants like lutein, zeaxanthin and anthocyanin. All of them are essential nutrients for combating multiple eye diseases.
