Protect Your Eyes: Blue Light Glasses & Computer Glasses

Blue light is a high-energy, short-wavelength light found in sunlight and digital screens like phones and computers. It can reach deep into the eye, affecting the retina and macula, which are key for clear vision. Too much blue light can cause eye strain and discomfort, and it may harm these sensitive parts over time. It also disrupts melatonin production, making it harder to sleep well. Managing blue light exposure helps protect your eyes and supports better sleep.

Blue light blocking lenses use special coatings or lens materials designed to absorb and reflect specific high-energy blue wavelengths—like those from phones, computers, and other screens we use daily. This means the harmful light is stopped before it reaches the sensitive retina at the back of the eye, helping ease the dryness, soreness, and fatigue that come from staring at screens for hours, while also giving your vision a little extra protection.

The blue light glasses may aid sleep for those using screens late at night by reducing melatonin suppression, offer mild relief from subjective eye strain for some, and benefit specific groups like post-cataract patients. While major authorities note limited general evidence, they can be worth trying for late-night screen users or those light-sensitive—opt for verified filtration to avoid color distortion and test for 1-2 weeks to gauge personal benefit.
