DGT prohibits the use of these sunglasses to avoid accidents.

Summer is approaching and this entails possible inconvenience for drivers due to longer exposure to the sun, greater intensity of sunlight. These reasons make many wear sunglasses, but, Did you know that not all of them are DGT approved?

It’s true that wearing sunglasses can help a lot when it comes to reducing driving glare, and with it reduce one of the most well-known risk factors of the summer seasonbut we have to be careful what glasses we use.

And the fact is that the DGT reminds us that not all of them are recommended for use, and even mentions that there is a type of sunglasses that are completely prohibited, which they do not perform functions that help reduce visual fatigue, the risk of blindness or temporary blindness.

Sunglasses with a solar filter 4 that absorbs up to 92% of UV rays are not allowed to be used while driving in the summer, as it reduces the amount of light so that we may not be able to see certain objects or identify them. they are well dear.

The use of sunglasses 4 limits the passage of light. maybe even counterproductive. This is why it is recommended to use glasses with a 3 filter, which continue to reduce light penetration a little, but not to such an excessive degree.

These goggles filter between 81 and 91% of UV rays, and it is advisable to use those that are closer to the first digit or at least in the intermediate zone.

To help us with the daunting task of preventing glare in the summer, DGT offers a set of guidelines that must be followed not only for road safety, but also for the health of our eyes.

Here are the recommendations of the agency responsible for traffic in Spain:

• Wearing polarized sunglasses with greenish, gray or brown lenses..
• In case of blinding by the sun, follow the trajectory and reduce speed. Don’t brake hard.
• With the sun ahead it is advisable to stop for a few minutes so that the sun changes position and don’t blind us.
• To avoid eye fatigue from the sun while driving, slow down and stop periodically to rest.
• Turn on your car’s low beams (if you don’t have daytime running lights) to make yourself more visible to oncoming traffic.
• Always use the sun visor at certain times as it reduces the field of view.
• Keep your car windows clean. Dirt reduces the field of view and increases the chance of blindness.
• Do not drive with sunglasses on at night, in dark places or in tunnels.
