How should I judge text readability on Even G2?
Use short text containing unfamiliar names, punctuation and numbers, and read it with the frame fitted as you would wear it. Move between the center and edges of the visible area. Fit and layout can affect different parts of the result.
Separate an optical problem from a writing problem
Start with a simple card before judging a dense paragraph. If a short word is difficult only at one edge or frame position, adding fewer words may not fix the optical issue. If all letters are clear but you keep losing the meaning, the layout or amount of text may be the problem.
A sample such as a meeting title, time and room number gives you details to retrieve rather than a picture to admire. Look away and return, then repeat with another card. Record misread details and frame adjustments instead of relying on the impression that the screen looked sharp initially.
