Ever notice how you can see your spreadsheet perfectly at 9 AM, but by 9 PM, your novel is a total blur? It’s not just tired eyes, it’s science.
The “sweet spot” for vision (the focal length) changes depending on what you’re doing:
💻 Office distance: Usually 20–30 inches away. Your computer monitor sits farther back to reduce neck strain.
📖 Bedtime distance: Usually 10–14 inches away. We tend to pull books/phones much closer when we’re propped up on pillows.
If you’re using the same pair of glasses for both activities, your eye muscles might be working overtime to help you focus. The result? Headaches, “heavy” eyelids, and losing your place in the story.
The fix: A dedicated pair of lenses set specifically for each activity.
