Asides from winking at everyone all the time, which can get really awkward when they think you're flirting, life with an eye that doesn't blink is a pain in the, well, eye. 

Whenever the weather is windy and cold or hot and bright, a none blinking eye suffers. Wearing glasses helps protect against wind and cold (cold eyeballs hurt) and help stop bits of dust and grit etc. from getting in my eye, which my blink should protect from. Sunglasses pretty much whenever light levels are above gloomy are a must as your eye is open and exposed to UVA/UVB rays basically all the time. 

Because my eye doesn't close completely, simple things like washing my face, washing my hair (especially having it washed at the hairdressers), spraying hairspray, dying my hair (hair dye in your eye hurts like a b**** for hours!), swimming, splashing with water with the kids all became issues. 

In the acute phase of BP, sleeping is fun too; making sure I don't scratch my cornea on your pillow or duvet and being woken up early because open eyes think it's morning sooner. 

As the blink doesn't work to lubricate the eye, dry eye is a real problem and means eye drops and gels just to keep it hydrated. Dry eye hurts, a lot. The FP eye gets tired quicker when driving, using a computer etc.  

At 16, I had perfect vision, good enough for the RAF to consider letting me near the controls of a fighter jet. Now my vision in my FP side is 3 times worse than in my good side. The optician thinks the dehydration, extra exposure to light, the atmosphere and irritants and being used more, because it doesn't get the blink rests, are probably contributory factors.
