my mom loves those and we always have them at home ill try them
i have 8 dioptries of shortightedness and on sunlight i see decently, at times perfect, without glasses thanks to training but my night vision glasses off is terrible
well thanks for mentioning time to take my glasses off and go on with my training
im trying to learn to control the cilliary muscles farther(focusing) and plan to start with miosis(pupil dilation)
edit:
also i have to say when i see a kid with glasses it brakes my heart:
the optometrist that dealed me in my childhood, not the one who put me glasses, explained me than glasses make shortsightedness worse, she would therefore underprescribe my glasses
so really if a kid just had a small shortsightedness putting glasses will make it worse while if he didnt use ithem as my niece she didnt need them farther and kept the just samll shortsightedness
but bisness is business yoou know even for kids health
edit
not to mention the good stuuf is not viable economically
