Question for Opticians - Aquatic

[feder1]

A prescription scuba mask was purchased a while ago and now we wish to sell it since succesful cataract surgery has been done.

The user had Right Spherical +7.75 and Left Sp. 6.75 for ordinary long sight corrective spectacles at the time of scuba mask purchase 20 years ago.

DAK whether we should simply advertise this pre-loved mask with this data or would an adjustment have been made for manufacture owing to water’s refractive index.

If anyone knows the answer to this I will eat my flippers.

Advertise the data as is and let the potential purchaser figure out whether it's an appropriate purchase for them.
