Why your lens replacement schedule matters
The date on the box isn't a suggestion. Replace on schedule — not on how the lens looks.

Appearance is a poor replacement signal
A soft lens can look perfectly clear while its surface has collected deposits, its shape has shifted slightly, and its comfort has quietly declined. Wearers often notice this as lenses that used to feel better, and they blame their eyes instead of the lens.
Protein and lipid deposits build up gradually, and humid climates like Indonesia's can make that buildup feel more noticeable. Your replacement schedule is set by the lens design and your eye-care professional's assessment of your eyes — not by what you can see in the mirror.
