Sun burn can occur due to two reasons- either excess heat by infrared component of sun light due to prolonged exposure or due to damage by UV component, which is present in abundant in sun light. About 2mm thick ordinary glass can cut off most of the UV in sunlight. Tinted glass can only reduce other component of the light, which reduces overall intensity of the spectrum. It is very helpful to reduce the heat-producing component. It also helps to reduce the total light energy influx into the vehicle. Usage of glass or tinted glass is only reduction of the problem but not complete elimination. Sometimes, when sun is very intense, we may still feel uncomfortable. Cloth screens may be used to avoid such problems.
