Parents, Did You Know?

UV rays are known to be both scattered and reflected even when you are in the shaded area. It is important to consider using a dark cover for the side windows of your vehicle especially when your little one is on board. Untinted car windows are made of high-quality clear glass which successfully blocks the UVB radiation, however, it prevents only 21% of the UVA radiation. Therefore, owning car window shades for your baby can be a lifesaving investment.

Parents, Did You Know?

Babies have extremely sensitive skin which is prone to easily burn when exposed to direct sunlight. There is epidemiological research which warns parents of the harmful effects that solar UV has, and the possibility to stimulate the development of melanoma during childhood. It is indicated that babies should be guarded against UV exposure from the day they arrive on this world especially infants under 12 months when the UV levels are above 3, in order to prevent future skin cancer risk.

Other Factors to Consider

Adjustability

While most of these items are simply held to the window and rubbed in place, one of them has suction cups to attach to the windows. The others use static cling to stick to the glass for trouble-free installing. Any of these can be repositioned or removed easily to be placed elsewhere and relocated. They will not lose their adhesiveness and will remain secured so you can focus on your ride while your baby is kept safe from damaging sun rays in its car seat.

q: What is a common complaint from online buyers concerning these items? Why?

a:

The fit and the level of shade are the most mentioned aspects online by customers. The tint of shade was not always what was expected. The fit of the shade to the individual car windows was not always perfect, so they might leave cracks or spaces where there was not any protection at all.
