Is the EVF on GX9 really worse than that on the GX7

Any reason not to wear your prescribed glasses?

I never needed glasses until I was 50 and my eyes are still good enough that glasses are an option, not a requirement. Unless I am driving at night or looking at something up close. I could probably get by without prescription sunglasses but if I am going to be wearing sunglasses anyways they might as well correct my astigmatism and myopia.

I see. Might your astigmatism affect the clarity of the evf (=a bright light source) if you look at it with a naked eye?

Usually presbyopia would be developed with age instead of myopia. I can, if use evf only, adjust the diopter to correct for my eyesight, but sadly only to one side: either my far seeing or close reading. Therefore I change to progressive glasses, set the evf for my mid range eyesight, when look at the LCD, can use the close reading range (lower part of my glasses) and when hold my head up, use the far sight region (the upper part of my glasses). These glasses are very convenience, but not only cost a lot more, also need to change quite frequently (every 1~2 years) because while myopia improves slowly, presbyopia develops fast...

IMHO sunglasses never work with evf well. For the evf, particularly the TFT type of GX7/85/9, polarized sunglasses is still a big no. I had a lot of prescribed sunglasses in my life, some of them are still highly usable (not for reading). But I lock them up after moving onto mirrorless.

Live View based shooting of mirrorless requires a precise understanding on the simulated image for an optimal setting, from exposure condition, WB, saturation and to certain degree, contrast (histogram is more useful) on top of the only focusing and composition of ovf. Most of my deeper color sunglasses affect my judgement (reduce the brightness, color shifting etc). I am currently using a pair of 99.9% UV cut Hoya clear glasses, and in case of very bright sunlight, shall use an UV400 rated pale light color clip-on sunglasses to make my eye slightly more comfortable.
