If you exceed the allowed vision or hearing limits while attempting to obtain your DGCA Class 1 Medical Certificate it means you are temporarily unfit or in more serious cases, permanently unfit to hold the certificate.
For vision: the standard for vision under what is commonly referred to as What Is DGCA Class 1 Medical states about distant vision 6/6 with or without correction, colour vision tests like Ishihara and limits on spectacle power.
For hearing: standards such as pure-tone audiometry threshold of around 20-25 dB in each ear for certain frequencies are indicated.
If you don't meet these thresholds:
You may be given atemporary unfit status: you'll be asked to get corrective treatment (e.g.glasses, LASIK for vision ear cleaning or treatment of hearing issues) and re-present later.
If vision/hearing deviation is major or non correctable, you may be declared permanently unfit meaning you cannot proceed to hold or upgrade the medical certificate required for a commercial pilot licence.
Since the certificate is mandatory for obtaining a commercial pilot licence (CPL) and being declared fit for professional flying, failing to meet these standards means your training and career timeline will be delayed or may become unviable. The article What Is DGCA Class 1 Medical emphasises that without this medical fitness clearance you cannot get the licence.
Get a full evaluation from an ophthalmologist (for vision) or an ENT/audiologist (for hearing) and understand whether the problem is correctable.
Maintain and restore your health: for vision use prescribed correction limit screen time before test for hearing avoid loud noise clear ear wax treat any infections. The article mentions eye issues or hearing threshold problems are common reasons for temporary unfitness.
Re-schedule your medical exam once you've corrected or improved the condition to meet the required thresholds.
During your preparation for the exam consider booking it early so you have time to fix any issues that come up and avoid delaying your training.
