Monitor hoods block ambient light from striking the screen surface at angles that cause glare reflections — typically from windows behind or beside the viewer, overhead fluorescent lighting, or bright light sources across the room. Glare on a monitor screen forces the eye to compensate for contrast reduction (bright reflections competing with on-screen content) through sustained pupil constriction and vergence adjustment, contributing to eye strain over a full work session.
The practical use case is clear: a desk positioned facing a window, in a room with large skylights, or in an office with uncontrolled overhead lighting often produces monitor glare that can't be resolved by screen brightness alone. Monitor brightness increased to overcome glare creates its own fatigue through excessive luminance exposure. A monitor hood is the structural solution — blocking the light path before it reaches the screen.
Monitor hoods are also used professionally by graphic designers, photo editors, and video colorists to ensure accurate color perception by eliminating ambient light interference. Professional color grading requires controlled viewing conditions; a monitor hood provides this without a dedicated studio setup.
Understanding the key specifications
Compatibility — monitor size and VESA/stand fit: Monitor hoods attach to the monitor frame either via friction clips, adhesive strips, or a VESA-mounted arm. Most consumer monitor hoods are sized for specific monitor size ranges (24–27 inch, 27–32 inch) and attach around the monitor bezel. Professional hoods are custom-sized for specific monitors. Verify the hood's listed monitor size compatibility against your monitor's screen size (not overall dimensions) — a hood sized for a 27-inch screen on a 32-inch monitor leaves gaps.
Depth — side shield length: The side shields of a monitor hood block light entering from the sides. Deeper side shields block more of the ambient light angle range — useful for setups with windows at sharp angles. Shallower hoods block only the most direct glare paths. Professional hoods (for color work) use deeper sides to create a nearly controlled viewing chamber; consumer hoods use moderate depth sufficient for typical office glare reduction.
Velvet vs. matte finish interior: The interior of a monitor hood should absorb reflected light rather than creating secondary reflections inside the hood itself. Velvet interior lining provides the lowest reflectance — appropriate for color-critical work. Matte plastic or matte fabric interiors are adequate for eye strain reduction. Glossy interior surfaces create internal reflections that defeat the hood's purpose — avoid these.
Portability — rigid vs. foldable: Rigid monitor hoods provide the most complete light blocking but don't collapse for transport. Foldable hoods (accordion or hinged) travel in a bag and set up without tools — appropriate for users who work in different locations and need glare control at each.
Our top picks
1. Photodon MXB Monitor Hood — Best custom-fit professional monitor hood
The Photodon MXB line offers monitor hoods custom-sized for specific monitors including popular models from Dell, LG, BenQ, and Apple. The custom fit eliminates the fit gaps of universal hoods — the hood mounts flush to the specific monitor bezel, creating a complete light blocking chamber with no light leakage from poorly fitted edges.
The interior is velvet-lined — the lowest reflectance interior available, appropriate for color-critical photo editing and video grading. The magnetic attachment system allows quick removal without adhesive residue. Side shields are 4 inches deep, blocking a wide angular range of ambient light entry.
Photodon manufactures the hoods to order for specific monitor models. Before ordering, verify your monitor model is listed on Photodon's compatibility page. For color professionals who need controlled viewing conditions, the custom fit and velvet interior justify the premium over universal hoods.
Best for: Photo editors, graphic designers, and colorists who need accurate color perception, professional home offices where monitor color accuracy is a workflow requirement, monitor sizes with specific bezel dimensions that universal hoods don't fit cleanly
2. Light Seal Monitor Hood — Best universal foldable monitor hood
The Light Seal universal monitor hood uses an accordion fold design that collapses flat for storage and deploys around the monitor without tools. The hood attaches via adjustable clips that fit monitor sizes from 21 to 30 inches (horizontal width). Side shields fold out and lock at 90 degrees to the screen plane.
The interior is matte black fabric — not velvet, but adequate reflectance reduction for standard office glare control. The accordion fold means the hood sets up in 30 seconds and stores in a slim profile. For users who work in different locations (office, home, client site) or who want to remove the hood when not needed without permanent attachment, the foldable design provides this flexibility.
The universal fit produces slight gaps at the monitor corners where the rectangular hood meets the monitor's specific bezel profile. For standard office glare reduction these gaps don't significantly affect performance; for color-critical work, a custom-fit hood provides better light control.
Best for: Mobile workers needing glare control at different desks, home offices where the hood should be removable without adhesive, users who want quick deployment and storage without dedicated setup
3. Llano Monitor Privacy Screen with Glare Filter — Best combined privacy and anti-glare solution
The Llano monitor privacy screen is a matte filter panel that mounts on the monitor surface — it reduces screen visibility to viewers at angles greater than 60 degrees (providing visual privacy in open office environments) while simultaneously providing anti-glare coverage through the matte surface treatment.
This isn't a monitor hood — it doesn't block ambient light entering from the sides — but it does address the most common glare source: reflections off the monitor glass surface. Matte privacy screens replace the reflective glass surface layer with a matte filter, reducing the mirror-like glare that glossy monitors create in bright environments.
Available for 24, 27, and 32-inch monitors. The screen attaches via adhesive strips or snap clips depending on monitor bezel type. The matte treatment reduces screen brightness by approximately 20% — factor this in for monitors used in dark environments where maximum brightness is already needed.
Best for: Open office setups where both privacy and glare reduction are needed, glossy monitor users who experience strong reflection glare from overhead lights, setups where a full hood isn't practical but surface glare is the primary problem

Setting up a monitor hood effectively
Step 1 — Identify the primary light source causing glare before purchasing: Stand at your desk and look at the monitor during peak glare hours (usually late morning or afternoon depending on window orientation). Identify where the glare is coming from: behind you, from the side, or from overhead. A monitor hood blocks glare from above and sides; a matte screen filter blocks surface reflections from any direction. Choosing the right type requires knowing the glare source.
Step 2 — Calibrate monitor brightness and color after installing a hood: A monitor hood changes the viewing environment — ambient light contribution to the perceived image is reduced, which may make the existing brightness and color calibration slightly off. After installing a hood, readjust monitor brightness for comfortable viewing in the new controlled environment (typically lower brightness than without the hood) and re-run any color calibration profiles.
Step 3 — Ensure interior surfaces are matte and non-reflective before first use: Check the interior of any rigid hood for reflective surfaces (shiny plastic edges, glossy interior seams) that could create internal reflections from the monitor light itself. Mask any glossy interior surfaces with matte black craft tape — a $5 fix that eliminates the only common hood performance problem.
Step 4 — Position the hood so it doesn't enter the screen field of view at normal viewing distance: From the seated work position, the hood's front edges should be at or slightly beyond peripheral vision — visible when looking toward the extreme corners of the screen but not intruding on the primary working area of the display. If the side shields are in the central field of view, extend the hood further away from the screen or adjust the side shield angle.
Frequently asked questions
Does a monitor hood actually help with eye strain? For setups where glare is a contributing factor to eye strain, yes — removing the glare source provides measurable relief. If glare isn't a contributing factor (the room is dim, the monitor is matte, or there are no bright ambient light sources), a monitor hood provides no eye strain benefit. Test for glare by placing your hand above the monitor at desk height — if it casts a visible shadow on the screen, glare is present. If no shadow forms, ambient light from above isn't reaching the screen.
Are monitor hoods worth it for video calls? For video calls, a monitor hood creates more even facial lighting — the front of the face is lit by the monitor, but the hood reduces the overhead and side light that can create harsh shadows. For users who appear on video calls regularly, the controlled lighting environment a hood creates can actually improve video call appearance. This is secondary to the eye strain and color accuracy benefits, but a meaningful consideration for remote workers.
Can I make a DIY monitor hood? Yes — matte black foam board (available at craft stores) can be cut and assembled into a monitor hood for $5–$10. Three pieces: a top board the width of the monitor and deep enough to extend 4–6 inches forward, and two side pieces the same depth. Assemble with matte tape. The DIY version works identically to commercial hoods for light blocking; it lacks the professional finish and quick-attach system of commercial options. For users who want to test the benefit before investing in a commercial hood, a DIY version is a practical experiment.
