We have a similar issue and have planted laurel bushes late last year to our front. They haven’t been in long enough to do their job but I live in hope of a good result in the next couple of years.

Not sure a more instant solution planting wise .

Good luck

Photinia Red Robin..............great Evergreen shrub / bush. Lovely red leaves on the new growth which then turn green. You can buy these as larger or smaller shrubs depending on your budget.

Pear Trees won't work, for one thing they're not evergreen and another it's a tree. Don't be fooled by this 'patio / dwarf' variety, all poppycock, they will reach their normal height if not constantly pruned. We keep all of our fruit trees to around 9 feet, but that's too high for outside a lounge window.

We have our Photinias planted for privacy reasons, but we've got them as standard plants. Therefore, the light comes in over and under the head of the plant, but the head is around 5 feet high and stops people seeing directly in.

This is exactly what ours look like except this is in a pot and ours are in the ground. I would have gone outside and taken pics ( maybe later ), but it's tipping it down again!

Completely separate point but you could also consider a window treatment for privacy as you might want to ensure any planting doesn't block light coming into the room

like the trellis idea you can grow plants of your choice. If you have Venetian blinds (done it) or shutters you can angle the slats to let in the light but still give privacy, Venetian blinds tend to let in more light as they dont have a lot of surround.
