This is a test based on the Parinaud scale used by opticians and ophthalmologists to test your near vision. This near-vision reading test provided by Le Petit Cordon UK for informational purposes only and does not constitute an eye exam performed by an ophthalmologist.
Finally, a general recommendation for the necessary near vision correction, made by ophthalmologists based on a person’s age, is as follows:

+2.00 |
