Blue light glasses are gaining a lot of popularity these days as people are discovering more and more merits of it. The increasing awareness of retinal damage and digital eye strain<\/a> caused due to prolonged exposure to blue light emitted from devices like smartphones, computers, laptops, tablets, have increased the demand for blue light blockers. <\/p>\n\n\n\n

So after all that buzz about blue light blockers, you must have thought of buying blue light glasses<\/a> but how will you know if your glasses have anti-blue light? <\/p>\n\n\n\n

It is unfortunate that many retailers claim to reduce blue light completely and fraudulently sell ineffective glasses. Poor buyers take their word for it. Okay, now blocking all of the blue light will hamper the screen viewing experience and make it uncomfortable. In fact, if the blue light gets completely blocked, the screen will appear red. <\/p>\n\n\n\n

So when it comes to testing genuineness of blue light, it can be a real task but can be done quite conveniently.<\/p>\n\n\n\n

Here is how you can test your blue light filters:<\/p>\n\n\n\n

Request for Transmitter Spectrum <\/h3>\n\n\n\n

This is something which you need to do right before you buy blue light glasses. You can request for the transmitter segment from the retailer. It is a graph that indicates the percentage of light passing through the blue light blocker as per the wavelength. <\/p>\n\n\n\n

The most effective blue light filter can block around 520 nm of blue light while some can block light below 400 to 480 nm. However, the more the glasses block blue light the more colours will distort.<\/p>\n\n\n\n

Use Blue Laser <\/h3>\n\n\n\n

This is another convenient way to check if your glasses block blue light. You can ask any optician for a blue laser<\/a>.
