When In the Phillipines we were told that the finely embroderied linens and hand made lace were made by young women because by 30 they were no longer able to see well enought to work. Their eysight was permanently damaged by years of very close work in very poor lighting

By age 30, in everyone the accomodative (focusing) mechanism has slowed considerably from that of childhood. This is age-driven and again has nothing to do with lighting conditions. Many of us become MORE nearsighted because of prolonged nearpoint work in childhood, but that in MOST case would make the embroidery task EASIER, unless their nearsightedness progressed to a severe level in which case the focal point would be too proximal to be useful for handheld tasks.
Again, this would not have anything to do with lighting conditions.
Visual acuity decreases with age if you do close work or not.
