I am long-sighted (+3.0/+3.5) and while I had to wear contact lenses (glasses are too uncomfortable, though they basically fit under an HMD) using the Rift DK2, I got along with the Pimax surprisingly well. But after a certain amount of time I felt my eyes were kinda stressed, and as I didn’t like fumbling in the contact lenses before every Assetto Corsa session, I searched the web for prescription glasses for the 4K and found your post.
Well, all I can say is “Thank you!”, as I recieved my pair of lenses from Hakunilan Optiikka yesterday and the result is an improvement absolute worth the money!
