Online reading test

This is a test inspired by the Parinaud scale used by opticians and ophthalmologists to test your near vision. This near vision reading test proposed by Le Petit Cordon UK is indicative and does not constitute an eye examination by an ophthalmologist.
Finally, a general recommendation of the necessary near vision correction, made by ophthalmologists according to one's age, is as follows:
| Diopter | Age |
|---|---|
+1.00 |
40 years old |
+1.50 |
45 years old |
+2.00 |
50 years |
+2.50 |
55 years old |
+3.00 |
Over 60 |
