About AdlensAdlens brings you adjustable focus eyewear because throughout your life, your eyes will undergo progressive changes. First, Adlens offers the Alverez Lens, an instantly adjustable set of lenses. Second, Adlens offers Variable Power Optics (VPO). These lenses, used in the AdlensRX Focus glasses, adjust to your vision's focus. The lenses actually mimic the natural behavior of your eyes. These glasses are not only different, but they also work in conjunction with how your eyes work. Adlens provides an interesting tool in which you see just how the Alverez and VPO lenses function. With the Alverez lenses, two plates move across one another for changing the power. They adjust by use of a dial on either side of the frames. The VPO has dials on either side as well, but discreetly hide where no one sees them. This dial produces pressure to a flexible membrane. The VPO lenses curve, due to the applied pressure. With a new technology especially made to protect your eyesight, remember to use Adlens coupons to get just the right lenses. You can use promo codes for the latest technology in eyewear.
