All drivers have been blinded by the sun at one point or another. Even wearing sunglasses may not be enough to reduce the bright light emanating from the sky. You could use the built-in sun visor, but it doesn’t always do the job adequately. More often than not, it’s too short to reach your eyes. Investing in a car sun visor extender is a great way to dampen the light. Here are the best sun visor extenders to consider for your next drive towards the horizon.

    Best Sun Visor Extender Reviews & Recommendations 2020

    Best Overall

    Glare Guard’s brand of sunshade visor extender connects easily to the already installed visor in your vehicle. You attach it with sturdy aluminum clamps, screws, and Velcro, and you can adjust the glass pane in front of your eyes and stow it away when the sun is down. The polarizing technology material adjusts light waves as they reflect off the windshield, reducing the harmful sun glare before it hits your eyes.


    The anti-glare sun visor is made up of a high-quality polarized acrylic film. The design makes it capable of withstanding up to 99.9 percent of harmful UVA and UVB rays. Another benefit of this sun visor extender is its weight—it’s just 12 ounces. If you need to move it to a different vehicle, you can do so with ease.


    Be aware that after driving in extended heat for a while, the screws may loosen, causing the visor to hang a bit lower. While it does a great job of reducing the sun’s rays, you will still need a pair of sunglasses to help block out the light. It also may not fit effectively in all types of vehicles, including RVs.

    Best Value

    The TFY Sunshade Extender is made from opaque polyurethane and attaches to the car visor with elastic bands. The opaque material effectively blocks harmful UV rays from blurring your vision and also protects your face from sunburns. It fits any car visor of about 5-7 inches, and it’s easy to take out the elastic bands when it’s not in use. 


    It features two polycarbonate, retractable slides that extend by 7.09 inches horizontally and 2.56 inches downwards. These slides work to protect you from sunshine glare or winter glow that penetrates the windshield and the driver's side window. When fully extended, the slides don’t let in little rays of light from where they attach to the sunshade extender. 


    Unfortunately, the TFY extender is not the best quality and the corners may start to chip after a short time. It may also be a bit challenging to deploy or push back the slides when you are driving. You may have to stop to adjust them. Moreover, the slides may come loose with frequent use.

    Honorable Mention

    Sailead’s visor extender uses a polarizing technology from NASA to filter out the sun’s reflected light rays. It attaches to your built-in visor and helps eliminate the distracting and blinding glare effect. This ensures your vision is improved and you don’t get eye stress, fatigue, or a migraine from squinting. 


    One feature we found particularly great is the extender's ability to be rotated up to 360 degrees. The design allows it to swivel and adjust to meet your eye level, so you don’t have to worry about sitting just right to avoid glare. Another nice feature is the durable Polycarbonate material of the visor; its 60 times stronger than glass, 20 times stronger than TAC polarized lens material, and 10 times more powerful than resin. It’s also impact, temperature, and scratch-resistant. 


    However, it is a bit clunky and can be seen by others from a distance outside of the vehicle. Another issue is it may not fit properly in all types of cars. Vehicles with smaller or thinner visors may find it difficult to effectively fit the extender on the visor. The screws holding the frame to the visor may also loosen over time but can be tightened with a screwdriver.

    Honorable Mention

    If you’re looking for the maximum amount of sun protection, then this dual sunshade is perfect. It’s made of PU and PC material and secured to your sun visor with elastic straps. You can use this visor on either a driver’s or passenger’s visor. It’s also versatile and can fit on visors that are bigger than 4.7 inches in width. The visor measures 12.2 x 5.1 inches and can extend 9.4 inches horizontally and 10.4 inches vertically. 


    What’s nice about this visor is that it’s made of the same materials that vehicle manufacturers use to construct their vehicles. It’s shockproof, compact, and very strong. This gives it durability. You’ll also find it easy to install since it doesn’t require any tools. It can fold away compact for easy storage. 


    Unfortunately, you’ll need to be careful when installing it so that the straps don’t have the hook part of the Velcro exposed. This could stick to your roof liner. Additionally, the visor can be susceptible to high heat.

    Honorable Mention

    Give both you and your passenger protection from the sun’s glare with this pair of visors. Each visor comes with two straps and an oval-shaped visor. To install, wrap the straps around your visor, then secure the visor panel to the straps. The visors measure 14.09 x 5.91 x 0.39 inches.


    What’s nice about this pair of extenders is that you can wrap the straps around any part of the visor in your car. This lets you customize how the extender blocks the sun. You can make them extend out to the side, or vertically to block the sun when it’s at an extreme angle during sunrise and sunset.


    Unfortunately, the straps on these extenders are wide and will block the use of your visor mirror. It also has an awkward method of storage where you slide the panel behind the strap. This means you can’t quickly flip the extender down when you need it.

    Honorable Mention

    If you want extenders that blend into your car’s interior, then these are ideal. They come in three sizes: small, medium, and large. They also come in black, gray, tan, black/gray, and black/tan. This lets you pick the perfect color combination to accent your vehicle. The small-sized visor will fit visors that are 4 to 5 inches. The medium extenders will work with visors that are 6 to 7 inches in size. The large size will fit visors that are 8 to 9 inches in height.


    These extenders are made from durable OEM-quality plastic for dependability. They’re simple to install and easy to use with a two-strap system and rectangular-shaped board.


    The downside of these extenders is that they feel flimsy. They can also fall out of place if you don’t securely install them. The straps can also block your ability to use the mirror on the visor.

    Honorable Mention

    This black window shade is a visor extender that doesn't specifically attach to your current visor. Attach this visor to your window to block the sun and ease your eye strain. It will also reduce the amount of heat transfer through the window. To install, slide them between your window and the trim. You can then remove them when not in use. Slide them between your seat and center console for easy-to-reach storage.


    You’ll like these extenders because they aren’t attached to your current visors, so they give you more flexibility in how you block the sun. They also have a 100 percent blackout ability, so no light gets through.


    Unfortunately, you can’t use these when your window is down. They need your window to be flush with the door trim to be held in place. You also can’t use them in other locations where there isn’t a place to slide them in. This makes them ineffective for blocking the sun in front of you.

    Honorable Mention

    This single silver anti-glare visor attaches to your flip-down visor to give you more protection from the sun. There are two straps that you wrap around the visor and then attach the extender to. The extender measures 14.09 x 5.83 x 1.18 inches. The straps are made of elastic with a hook-and-loop attachment. The visor is made of flexible light material for adjustability.


    What’s nice about this visor is that it can protect your eyes from ultraviolet light. This gives you increased protection and safety. The design of this extender gives you complete freedom in how you attach and adjust it.


    Unfortunately, you only get one extender, so if you want to outfit both visors, you’ll need to buy two. The straps that wrap around the visor will block your ability to use the mirror in your visor.

    Benefits of Sun Visor Extenders

    • Reduce glare. The light from the sun can be distracting and may also momentarily blind you during your drive. While the sun visor won’t block the sun’s presence completely, it will cut down on the amount of glare.
    • Reduce eye stress. Driving without a sun visor can be stressful on your eyes. Many drivers have to squint or lean closer to the steering wheel to get a better view when faced with the sun. This can lead to watery eyes or excessive blinking and rubbing. Sun visor extenders can help prevent eye strain by eliminating the amount of light that gets through to them.
      Prevent headaches. Your eyes are more sensitive when you look directly at a powerful light source for long periods of time. This is one way you can get a headache or migraine. Reducing the amount of light strain on your eyes can lessen the impact.
    • Get some peace of mind. By using a sun visor extender, you will be able to see better all day, especially when the sun is setting or rising. It makes driving less stressful by reducing the light, giving you more control of the wheel and better visibility on the road.

    Types of Sun Visor Extenders

    Window Mounted

    Window-mounted sun visor extenders attach to the passenger and driver windows in your vehicle. They are easily removable, reusable, and adjustable for your convenience. These visors can hang just at eye level or can cover up the entire window to completely blackout the sun, so you can see the road more clearly. 

    Visor Mounted

    A visor-mounted sun glare visor attaches to the built-in visor in your vehicle. It can be connected by velcro, straps, or screws. This type of visor can also work in several different ways to block the sun from your view. It can either hang down in front of your eyes or extend outward to the side.

    Top Brands

    Glare Guard

    Founded in 2013, Glare Guard is based out of Easton, Penn. The company focuses on designing polarized car visors to help drivers see more clearly while they drive. It makes visors for both intense summers of the coldest winters. One of its visor extenders is the Glare Guard Polarized Car Visor Extender.

    TuckVisor

    Located in McCloud, Calif., TuckVisor manufactures a selection of visor extensions to block the sun. One of its most unique designs fastens to the vehicle’s windows and can be custom shaped to conform to any window. Consider the high-quality TuckVisor Windshield Sunshade Best Sun Side Window Shade Visor.

    Sun Visor Extender Pricing

    • $15-$25: Sun visor extenders in this price range will offer the most basic protection against bright lights while also reducing glare. You can attach them directly to the visor in your car or to the windows.
    • $25 and up: The sun visor extenders in this price range have a wider selection of features and designs. Many come with a filter that is designed for night driving or have different polarized glass similar to sunglasses. These can aid in reducing glare from headlights, traffic lights, reflected surfaces, and harsh blue light.

    Key Features

    Material

    Many built-in sun visors feel frail and flimsy, so you want to find a well-made and high-quality extender. If you want one that connects directly to the visor, make sure it is durable and sturdy so it doesn’t fall off when you drive. The same goes for extenders that attach to the windows. Since you can remove and reuse them, find one that will hold tightly to the glass.

    UV Protection

    One of the most important things about a windshield visor extender should be how it protects you from the sun’s UV rays. Driving in direct sunlight can have the same effect as if you spent the entire day outside. Protecting against it will ensure you don’t get a sunburn or other side effects. If you live somewhere particularly sunny, we recommend investing in a visor with enhanced UV protection.

    Other Considerations

    • Size: You will want to find a visor extender that will fit your window or built-in visor properly. Some may not be equipped to fit in certain vehicles, such as SUVs, trucks, or compact cars. You can trim or cut some visor extenders if they are too big for your window.
    • Installation: You shouldn’t have to fuss around too much with how long it takes to install a visor extender. They should fit snugly and firmly on either the visor in the car or onto the window with ease.

    Tips

    • Sun visor extenders can even be used to help reduce the glare of the sun off of the snow. For any driver in a snowy region, a visor can make a huge difference on the road.
    • Sun visor extenders are just like sunglasses or reading glasses. If they get scratched or dust gets on them you can clean them with a cloth or towel. Many will come with their own microfiber cloths.
    • You don’t have to fully remove the sun visor extender when the sun is down. You should be able to fold the visor out of sight. Plus, many are fitted with a night vision feature for driving in the dark to reduce light glare from headlights. Check the manufacturer's guidebook before using them at night.

    FAQs

    Q: How can I test the polarization of the glass?

    A: You can test the polarization of any sunshade visor extender by turning your phone screen to the brightest setting and then viewing it through the glass. Rotate the phone 90 degrees until you see the color change. The shifting color is the polarization taking effect.

    Q: How do I tell if my sun visor extender works on the road?

    A: You may or may not see a clear difference right away when it comes to reducing glare. The human eye is complex and everyone’s is different. A good way to find out is to test it before you drive. To do this, look at the sun from a distance with the visor and without the visor. It may take some time for your eyes to fully adjust to the polarization effect. You may also want to try with and without sunglasses.

    Q: Will a sun visor extender act like a pair of sunglasses?

    A: While many do replicate the effects of sunglasses they may not be as powerful. You can wear sunglasses along with the visor to improve your vision.
