Govt job rejection due to one eyed amblyopia(20% visual defect) for pharmacist post?

As per ESIC act , ESIC follow DoPT first medical joining rules which is framed by MOHFW , as per this document for "TECHNICAL POST" one eyed/ amblyopia candidates are unfit , which is backed by the document of cabinet secretariat O.M.No.85/11/CF-61(1), dated 28th december, 1961, that clasify the technical posts. 1) But the ESIC provide reservation on some paramedical post(which are also i believe technical) for Low Vision candidate(40% disability), but the pharmacist post is not suitable for Low vision candidate. There is flexibility on this rule . 2) And as per Revised PwD act , 2016 i think , the DGHS of MOHFW , give guide line that , " FOR MEDICAL COURSE AND PERSON LESS THAN 40% VISUAL DISABILITY , CAN GET ADMISSION" . so the goverment is allowing the degree for upto 30% visual disability candidate , but as per the said guideline of pre-medical there is 99% chance that they will reject me . And i have seen many candidates get rejected on jobs. so , what should i do ? Should i appeal to court? If yes, where should i complain, do i have to go to the SC as its a central govt job or i should file the case in assam as this is where i got posted or can i file case on kolkata high court? i have 20% disability , is there any chance of winning?
