In this video, Dr. Radhika Torgal, Cornea and Cataract Surgeon at Shekar Eye Hospital, JP
Nagar, Bangalore, addresses one of the most frequently asked questions by patients: Are blue
light blocking glasses really helpful for the eyes?
Doctor explains that contrary to popular belief, blue light from digital devices like phones and
computer screens has not been scientifically proven to cause direct harm to the eyes. Instead,
adopting healthy screen habits—such as taking regular breaks, using lubricating eye drops,
maintaining good posture, and keeping an appropriate viewing distance—is far more effective
for eye comfort.
However, blue light can interfere with melatonin production, a hormone that regulates our sleep
cycle. Prolonged exposure, especially in the evening, may disrupt sleep patterns and lead to
fatigue. In this context, blue light blocking glasses can play a role in supporting better sleep
hygiene—even if they don't directly benefit eye health.
