A book in your hands. A screen on your desk. A view beyond the window. Your attention moves all day — and juggling pair after pair can interrupt the moment.

Meet Smart Zoom: progressive focus, photochromic lenses and blue-light filtering in one distinctive rimless design.

Progressive lenses use different areas for different viewing distances. The upper area serves distance viewing, the middle supports intermediate tasks, and the lower area supports close reading.

Knowing where to look helps you get familiar with your pair. The colored zones show the idea; they are not visible lines in the lenses.

• Look through the top for distance.
• Use the middle for a screen at working distance.
• Lower your gaze for the page in your hands.

Messages on your phone. Plans on your laptop. A recipe on your tablet. Smart Zoom brings blue-light filtering into the same pair you reach for throughout the day.

The graphic illustrates filtering at the lens, while the progressive middle zone supports viewing at an intermediate working distance.

Start with familiar tasks: a page, a screen and a view across the room. Take time to get used to the different viewing areas while seated in a comfortable setting.

The right fit and suitable lenses matter more than a product name. If you are unsure whether these readers meet your needs, an eye-care professional can help.

Illustrative scene. Model portrayal.

The curved temple tips, clear nose pads and folding arms are easy to overlook in a thumbnail. Here, you can see how the actual frame comes together.

Look closely at the contact points and construction before choosing your pair. A good everyday choice starts with understanding what you will wear.

A full-rim design places a continuous border around each lens. Smart Zoom leaves the edges open, making the angular lens shape the focal point.

Compare the two structures, then choose the look you can picture wearing. The full-rim pair shown is an illustrative design comparison.
