Key Design Features of Blue Blockers

Do you ever struggle to fall asleep? If yes, blue light may be one of the reasons behind it.

Both digital screens and artificial lights produce this harmful ray from about 430 nm to 500 nm with a strong point at 455 nm. So, when you work continuously in front of these devices, they considerably impact your eyes and sleep quality.

When it comes to getting relief from eye strain and ensuing insomnia, there are many options available in the market – like computer glasses, anti-reflective glasses, and gaming glasses. But, all of these options carry out the same function – filtering out the blue light. So, if you are not able to decide what pair will be perfect for you, here are some key features of blue light blocking glasses to look out for as you purchase your next pair of glasses:

Blue light blocking range- If you are shopping for blue light filter glasses, you need to first consider their quality. Percentage of total blue light blocked and a specific range of wavelengths is what differentiates high-quality glasses from average glasses. So, always look for lenses that have the capacity to filter at least 40% of blue light.

Frame color: You can find these glasses in different frame styles and colors according to your choices. As they are used for utilitarian purposes, they will be generally available in colors limited to more conservative colors such as black.  

Head size: Whether you are a kid or adult, these glasses come in a variety of head sizes. Blue light blockers are beneficial for people of all ages (who use digital devices continuously).

Prescription strength: In order to match prescription strength, some blue light filter lenses come with magnifications options. For example, BluTech Ultra and BluTech Classic are available in Rx, non-Rx, Reader options while BluTech Max is available only in non-prescription.

If you are now convinced about purchasing blue blockers, you can visit the website of BluTech to find the best dealers and shop near you. Shop for a pair of these lenses and get a perfect vision as well as proper sleep!
