<p>[QUOTE="desertgem, post: 24862270, member: 15199"]One should also keep in mind short wavelength blue light from the TV , sunlight, or the computer monitor. I bought a roll of thin yellow tinged window plastic with silver reflecting back outside. It does help if you are on inside devices more than a couple of hours a day. Or if that is too difficult , use a pair of yellow tinged welding glasses to block the blue. For me, 80 was when night driving got hard, modern car/trucks lights coming at you can be scary <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /> Jim[/QUOTE]</p><p><br /></p>
