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.

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.

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.

Best Sun Visor Extender Overall: Glare Guard Polarized Car Visor Extender

Glare Guard Polarized Car Visor Extender
Amazon

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.

TuckVisor Windshield Sunshade Best Sun Side Window Shade Visor
Amazon

As one of the more unique types of sun visor extenders, this one attaches to the driver- or passenger-side window. Its ergonomic design makes it capable of sticking to the majority of windows in your vehicle. You can even adjust the visor to your specific needs and height and then remove it and reuse it on another day. The tinted material provides a 100 percent blackout from the sun’s rays to improve your vision while you focus on the road.

Along with easy installation and removal, it is made up of a dense material that can withstand tears, folding, and fraying. At just 3.2 ounces, TuckVisor’s windshield visor can be stored safely between the center console and the seat. This makes it easy to grab and set up when you need it the most. Plus, it can fit in any vehicle without a hassle.

One downside to this visor extender is you may not be able to roll the windows down fully without damaging it. So, if you want to ride around with the breeze blowing, you will have to remove it. You also need to be careful when putting it on the window to avoid getting bubbles in the material. While that shouldn’t impact your view, it just looks odd.

Best Sun Visor Extender Honorable Mention: Sailead Polarized Sun Visor Extender

Sailead Polarized Sun Visor Extender
Amazon

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.

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.
