    📌 இந்த cricket stadium light மாதிரி night ல two wheeler ல அவ்ளோ bright ஆ head light போட்டு வர்றானுக. Blue intensity யும் அதிகமா இருக்கு. அதுக்கு opposite ல வரும் போது Helmet போட்டா கண்ணு கூசுது. Helmet போடாட்டி கண்ணே வலிக்குது. அந்த தடி மாடுகளுக்கு புரியற மாதிரி ஒரு video போடுங்க bro

    Government should make the rules strict for this kind of high intensity lights and horns. Now fixing of high intensity lights/horns becomes like competition and no one bothers about dimming the headlights or wise use of horns. Even scooters have high intensity LED lights and none of them have the practice of dimming the same. Infact dimming the headlight when the speed is slow is more safer and have more road visibility but no one realize this

    What you are saying is true.. i too faced problems with led bulb based on eyesight... exactly like your thumbnail.. one spot where the light hits became obscure for me and also caused migraine aura..( almost 20 mins i cannot see anything clearly.. search migraine aura you will get a clear video depiction.. ) i found that usage of led bulbs in the place of old tube light caused the issue.. I removed the light from that place and immediately the migraine aura reduced and now no more.. always have the light at the back side of your head .. frontal or side light sources form a spot on your eye when exposed for a long time .. in my case it was a side light source and the eye blind spot originated at that point.. only with that i found that the led bulb is causing the problem... Your thumbnail picturised the exact problem.. dont change it .. i saw the thumbnail and only because of the spot in eye i came to see video

    Hi Bro, One more thing to add, light emitted from leds are from point source. They are very sharp which which is not comfortable for eyes. This can be tested using shadow of hand. Scattered light are pleasing to eyes. The smds used are too tiny. This issue is only with bulb type lights.
