I have Eye allergy for more than 2 years

Hi doctor, During covid year i have started with my eye pain. I consulted nurse in eye hospital she told to wear glass and i had very less power and it is 0.25, but the pain still there, iam unable to look into lights, and iam. Unable work in laptop, the pain gradually increased in night. Then before 6 months i went to eye clinic they diagonised it as severe eye allergy. Then i was under medication for 3 weeks course, 2 months course and again 2 months. The pain was less when i took medication. But it will start again if the course ends... Now iam still in 2 months course again and now iam taking FLI drops, UV lube and sodium hyaluronate XL HA. The pain starts again and again. Is this eye alllergy will be solved permanently? Or should i need to continue the course again and again? Or should i need to visit other doctors?
