Reciting یَابَصِیْرُ 100 times after Friday prayer helps to cure weak eyesight and it leads towards pious acts.
One whose spirit or body is weak should writeاَلشَّکُوْرُ and wipe it on whole body. Similarly one whose eyesight is weak should wipe it on eyes.
After every prayer recite YA NOORO یَا نُوْرُ , blow on both hands and wipe on both eyes.
By reciting SURAH NABA weak eyesight gets cured. It is also beneficial to blow it on water and apply that water. HAZRAT KHAWAJA NIZAM UD DIN AULIA said that whoever will recite this SURAH 5 times after ASR prayer will get the wealth of love of ALLAH. (Fawaid al Fowadas: 94)
Reciting QURAN while looking at it increases the eyesight. Lowering the gaze also makes eyesight strong. One should also apply SURMA before sleeping which is SUNNAH. Eyesight is also increased by looking at moon. By reciting SURAH TAKVEER, eyesight is increased.
