you might find some spraycoating for dirt but it might actually cause glare.
harder glass is made not applied.
it would require machine but you might save by doing some coatings your self as in any other product but would you add seatheaters to your car if you saved $200? for me it would take more hours to learn about it than it would save as lenses are only half of the price and coatings are only max half of the price of lens. in the end coatings could save me $100 in every 2 to 4 years. normal human does not need to save $100 that bad.
now that i bought cheap ones i need to get new glasses inside a year and I have had these fucks on my head while i see glear and dirtstripes all the time. addition to discomfort buying cheap actually lost me money as i need to buy new ones 4 to 8 times more often for 1/4th of the price
>>60560991luxottica has poor quality brands and all the poor ones could be bought cheaper, but quality ones can't be made in china sweatshop.
in my experience gucci tier(used to be made by luxottica, don't know current maker) is best non custom made and it costs +400 for frames
cuggi quality is compareble to carrera (safilo) and serengeti(bolle brands)
cuggi is 1/3-2/3 more expensive, so yes luxottica has high markup as its dominating the market, but there might not be much markup in alternative real brands.
your knowledge of manufacturing seems non existent. cheap ones could be made for $30, but good ones are near 100-150 and then they need to do all normal business stuff like marketing and in the end custom lenses for you. everything has high markups in that core level but what is left might not be so glorious.
you could do everything your self and save. makes no sense tough, as most of the time you would lose more time than save money.
