Hello! First time poster here.
Erm let me just give a quick introduction, I'm a Pre-reg Do set to sit the final practical exams in June.
Nerve racking!
I just need a bit of help with a few questions!
Firstly,
Prism thinning- this topic still confuses me can anyone link me to some helpful sites? – or explain what exactly it is and what involves
Secondly,
Different PPLs- Hard/Soft/Firm-erm help?
I'm still confused as to how you tell the difference, and what actually is the deference. Examples?
Thirdly,
If given the following Rx what would one dispense?
Px: 6 years, full time spec wearer
R -3.00/-1.00x180 L-3.00/-1.00x180
Add +1.75
Many Thanks
