UV cannot be seen or felt. It is not like the sun’s light which we see, or the sun’s warmth (infrared radiation) which we feel. Our senses cannot detect UV so it can be damaging without us knowing.
The sun’s ultraviolet radiation is the best natural source of vitamin D. However, too much UV exposure from the sun and other sources, such as solarium is major cause of sunburn, premature ageing, eye damage, skin damage leading to skin cancer and it is the primary reason why the upholstery in a car fades over time. With 3M car tint, Dubai residents are protected from the harsh UV rays while inside their vehicles.
