I use uvex clear or grade 5 safety glasses from the welding supply. Wrap around edges, and fit under the full face helmet. Keeps me from paying $12 shipping from Amazon. Amazon shipping is 50% higher than UPS now, and 150% of USPS. Amazon thinks I want to watch their stupid soap operas. Streaming goes to this 11" screen and a stack chair, KET (edu TV) signal goes to a 30" screen and an upholstered chair. Watched Canadian archeologists retrieve perfectly preserved wood & bone spears from ice banks last night, with points held on with sinew and feathers. 4000 years old. My ancestors.
