Many of my readers have been hearing about the importance of blocking blue light from LEDs and artificial light sources. With the extended use of laptop, cell phones and gaming devices we are being bombarded with this dangerous light. Did you know there are different wavelengths that are emitted by these devices. The gold standard for blocking the short, high intensity wavelengths are lenses made by BluTech. All other blue blocking lenses block at 420nm. and only block 7-10% of blue light at 455nm. Why settle for lenses that don’t do the job. At Sarlin Opticians we specialize in BluTech lenses for prescription and non prescription glasses. Come in or call to answer any questions you might have.
