Glass skins (tints, blockers and security/privacy one ways) are by and by UV blockers to save interior furnishings from sunlight damage as well.

Mini blinds can be had with the added option of raising from the lower window frame, even mid, rather than from the top as always seen on the good ol days blinds.
Quilted are best for day and night block and helpful in the summer and winter temp extremes.

Glass blocks come in the often seen thick square blocks and currently in a vast array of thicknesses and shapes.
Even have LED lights for an option to glow the bricks at night.

Even a wave glass window pane or panes offer privacy and let the sunlight thru, although greatly defused.

Shower stall glass is thin, tempered glass that greatly defuses the light and thereby making any objects mostly unrecognizable.

Laced shears will keep outside eyes from actually seeing the interior in any meaningful detail and even most inside movements.

Many options to consider and taking into account the cost, temporary installment if need be, appearances, style/decor and level of privacy/security.

So long as the outdoor light is brighter than the indoor light at all times, the chosen window treatment will work well.


Always have an object, bush or whatever is appropriate infront of the window so an outsider cannot get their face on the window and shield the background light to see inside easier than not.:wtf:
