When does presbyopia start?
It usually begins to be noticeable around the early forties and continues to change, slowly, for decades. The timing varies considerably between people, and it is affected by your existing prescription: short sighted people often notice it differently from those who have never worn glasses.

In more detail
The reason there is no single age is that presbyopia measures the flexibility of the lens, and that changes gradually rather than on a birthday. What most people notice first is not blur but a need for more light, or holding print further away than they used to.
What this answer depends on
- Your age and how fast the change is progressing
- Your distance prescription
- How much of the day you spend reading or on screens
