By wearing close-up, computer, or near work glasses, you increase your blur horizon just to the point where you can see the screen clearly, but the rest of the world is still somewhat or very blurry without wearing stronger correction. This is perfectly fine and part of the plan — computer glasses are only meant to correct you for a set distance. | ||

Emphasis on '''''nearly''''' — it is crucial for the blur horizon to be slightly undercorrected and challenging your vision when compared to a full correction an [[optometrist]] is likely to give you. Being slightly undercorrected is perfect, as too much undercorrection will both stagnate improvements and cause you to [[blur adaptation|live in blur unnecessarily]]. | Emphasis on '''''nearly''''' — it is crucial for the blur horizon to be slightly undercorrected and challenging your vision when compared to a full correction an [[optometrist]] is likely to give you.
