Hi, I would suggest that you see an oculoplastics surgeon. Ptosis of the eyelid is common with contact lens use. Excessive stretching of the skin of the eyelids is also a common cause. Both factors contribute towards sensation of heaviness of the eyelids and tiredness. In advanced cases patients lift their eyelids manually to get better view.
Each surgeon decides the appropriate gap payment as they see fits after assessment of what works are needed. You are welcome to visit my practice which specializes in this area if you are based in Melbourne.
