Most people think an expired glasses prescription is just a rule.
It’s not.
Your prescription isn’t a fixed number — it reflects how your eyes are functioning at a specific moment in time.
And the truth is… your vision is constantly changing.
Here’s why:
• Increased screen time (phones, computers, tablets)
• Prolonged near work (reading, office tasks)
• Aging and natural loss of focusing ability
• Dry eye and tear film instability
• Changes in nearsightedness, farsightedness, or astigmatism
• Reduced blinking from digital device use
• Stress and poor sleep quality
• Diet, hydration, alcohol, and smoking
• Hormonal changes (pregnancy, postpartum, menopause)
• Medical conditions like diabetes or high blood pressure
• Side effects from medications (antihistamines, antidepressants, etc.)
• Early eye conditions (cataracts, keratoconus, macular changes)
That’s why we don’t just think in terms of “prescriptions.”
We think in terms of lens recommendations — tailored to how you actually use your vision.
Because seeing “okay” isn’t the goal.
Seeing your best is.
