Reading glasses +1.5 – the most common strength for everyday reading.
+1.5 is where most people end up. You've been noticing the strain for a while – the book at night, the text on packaging, the screen at work. This strength gives you sharpness up close without feeling too strong. It suits most people in their mid-to-late 40s and is a natural next step if +1.0 is no longer quite enough.
