    It depends on the lens power and the larger your spec frame, the thicker your corrective lens will be. Happily we can now use a range of high refractive index lens materials and smarter optical design to significantly reduce the thickness and weight of your spectacle lenses over basic lenses. This is especially good news for people who need high prescriptions and/ or wear their glasses all day and are weight sensitive due to sinusitis or broken noses. Double sided Anti-reflection coatings combined with Scratch Resistant coatings protect the lens surface, improve night vision clarity and allow your spec frame to appear optically empty. Your eyes can be seen clearly behind your lenses. With these lens coatings and thinner lens technologies you'll look your best in specs.If you are a Progressive lens wearer, you will see your stand alone computer screen more comfortably if you lower your screen 20cm below eye level when you are seated at your desk. The most comfortable viewing experience for screen and office work for Progressive lens wearers is to use an extended near focus lens such as Hoya's Desk lens series. Great relief for aching neck syndrome.
