Choosing Your Strength
Start with the readers you already wear as your bottom (reading) power, then choose a milder top power for computer and mid-range vision, ideally at least 1.00 diopter weaker than the bottom, for a smooth, comfortable transition without eye strain. If you spend more time on screens than reading, lean toward a gentler top power.

Why Traditional Readers Fall Short
You can’t see everything clearly at once
Your book is sharp, but your screen isn’t.
Why it happens:Traditional readers focus at only one fixed distance.
Result:You lean forward, tilt your head, or constantly adjust.
You keep switching glasses
On. Off. Swap pairs. Repeat.
Why it happens: Standard lenses aren’t built for how people actually move between tasks.
Result: You now manage two pairs of reading glasses to navigate your day.
Your eyes feel tired too soon
By afternoon, your eyes feel strained.
Why it happens:Your eyes compensate when lenses don’t match real working distances.
Result: Fatigue, tension, and reduced comfort.
Custom-built in partnership with experienced opticians —designed to fit the way you actually use your vision.
