Cheap plastic strips often warp under afternoon heat, while premium options maintain a rigid light barrier. I have tested dozens of these accessories to see which ones actually eliminate annoying bedside glare. Read on for my honest ranking of five popular choices.
1. Bliwans Light Blocking Strips for Window Shades and Blinds, 100% Blackout PVC Side Tracks Light Blocker for Blinds, Window Light Blocker for Bedroom(White, 58", 2PCS)
This option earned its solid ranking through consistent coverage on standard bedroom frames. The 58-inch PVC channels block stray rays effectively once you mount them flush against the wall.
I prefer this setup for ordinary guest rooms where complete darkness matters more than fancy installation hardware. You might find the rigid material a bit unforgiving if your window casing is slightly uneven.
Buyers note that the length suits standard vertical drops quite well.
Users often mention needing their own measuring tape for a clean cut.
Reviewers appreciate the straightforward design for basic bedroom setups.

2. 100% Light Blocking Strips Blackout L-Shaped PVC Dual-Side Tracks – for Cellular Blind, Window Roller Shades,Blinds & Window Shades – Easy to Install for Bedroom & Nursery (White, 58.5",2Pcs)
This is my top pick for anyone chasing maximum darkness in a nursery or shift worker's bedroom. The dual-side L-shaped profile catches light from multiple angles far better than flat channels.
I rank this first overall because the physical geometry creates a true shadow trap against the wall. You will need to take your time with scissors or a saw to trim the PVC accurately.
Customers consistently praise the complete elimination of side glare.
Reviewers highlight the sturdy L-shape as an upgrade over flat strips.
Buyers emphasize the importance of careful measuring before installation.

3. Toperblinds Roller Shades Light Blocker Strips, White 15.75'' 10Pcs
You might be surprised by the shorter 15.75-inch segments in this kit, which target specific problem spots instead of full frame heights. This modular approach widens the appeal for partial fixes rather than total overhauls.
I like this configuration for patching annoying corner leaks without committing to full-length tracks. The shorter pieces require careful alignment to avoid looking patched together on your window frame.
Users find the shorter pieces handy for targeted gap repairs.
Buyers mention that ten pieces offer plenty of spares for multiple windows.
Reviewers point out the need for steady hands during alignment.

4. Blackout PVC Light Blocking Strips for Window Shades and Blinds – Blocks Light Along The Sides of Blackout Blinds,Side Tracks for Cordless Shades, Light Blocking Strips for Bedroom (White, 58",2Pcs)
Many buyers initially struggle with the adhesive backing peeling off during humid summer months. Despite that common hurdle, the rigid PVC material still delivers reliable side-channel shading once secured properly.
I view this as a practical choice for temporary spaces where you want results without permanent hardware. You should probably skip the factory adhesive and use stronger double-sided tape if your walls are textured.
Customers frequently mention upgrading the adhesive tape for better hold.
Reviewers note that the PVC blocks morning sunlight effectively.
Buyers advise caution when peeling the backing off the strips.

5. ZSTARR PVC Light Gap Blockers for Window Shades White 58'' 2pcs
Stepping down from my top dual-track recommendation, this simpler alternative offers a more streamlined profile for basic adjustments. It lacks the advanced light-trapping angles of the L-shaped competitor, yet it handles basic window gaps just fine.
I recommend this version if you want a no-fuss barrier without extra plastic bulk around your trim. You might notice minor light slippage if your roller shade hangs unevenly in the first place.
Users report a clean appearance on standard white frames.
Buyers appreciate the simple installation process for quick window fixes.
Reviewers note that basic adjustments require steady hand placement.

Choosing Between Them
If you want maximum darkness for a bedroom, choose the dual-side track design from my second-ranked option for superior light sealing. For standard spaces or quick fixes, the remaining choices offer solid alternative profiles to match your specific window dimensions.
You should always measure twice before cutting rigid PVC tracks to fit your unique frame geometry. Taking those extra few minutes guarantees a snug fit and prevents frustrating light leaks around the edges.
