blue light has a short wavelength. This is important because doctors associate short-wavelength light with greater risk for eye damage.
While many electronics (including lightbulbs) emit blue light, computer screens and televisions typically release more blue light than other electronics. This is because computers and televisions commonly use liquid crystal displays or LCDs. These screens may look super-clear and vibrant, but they also release more blue light than their non-LCD counterparts.नीले प्रकाश की तरंगदैर्घ्य लघु होती है। यह महत्वपूर्ण है क्योंकि डॉक्टर शॉर्ट-वेवलेंथ लाइट को आंखों की क्षति के लिए अधिक जोखिम के साथ जोड़ते हैं।

Too much blue light exposure is thought to:
affect your circadian rhythm, which can make it harder to go to sleep at night
cause headaches
increase eyestrain
cause visual fatigue
Blue light isn’t all bad, though. Because this wavelength is produced by the sun, it can promote alertness, signaling that it’s time to get up and start your day.
And a lot of studies on blue light and eye damage have been conducted on animals or in controlled laboratory settings. This makes it hard to know exactly how blue light affects humans in real-life scenarios.
