Say three times:

اَللَّهُمَّ عَافِنِي فِي بَدَنِي اَللَّهُمَّ عَافِنِيْ فِي سَمْعِي اَللَّهُمَّ عَافِنِيْ فِي بَصَرِي لَا إِلَهَ إِلَّا أَنْتَ اَللَّهُمَّ إِنِّي أَعُوْذُ بِكَ مِنَ الْكُفْرِ وَالْفَقْرِ اَللَّهُمَّ إِنِّي أَعُوْذُ بِكَ مِنْ عَذَابِ الْقَبْرِ لَا إِلَهَ إِلَّا أَنْتَ

Allaahumma 'aafinee fee badanee, Allaahumma 'aafinee fee sam'ee, Allaahumma 'aafinee fee basaree, laa 'ilaaha 'illaa 'Anta. Allaahumma 'innee 'A'oodhu bika minal-kufri, wal-faqri, wa 'A'oodhu bika min 'athaabil-qabri, laa 'ilaaha 'illaa 'Anta.

O Allah, grant my body health, O Allah, grant my hearing health, O Allah, grant my sight health. None has the right to be worshipped except You. O Allah, I take refuge with You from disbelief and poverty, and I take refuge with You from the punishment of the grave. None has the right to be worshipped except You. Abdur Rahman ibn Abu Bakr (RA) said that he told his father: O my father! I hear you supplicating every morning. You repeat them three times in the morning and three times in the evening. Then Abu Bakrah said: I heard the Messenger of Allah (ﷺ) using these words as a supplication and I like to follow his practice.
