UV UVA UVB rays in home house- problem?

I live in Florida and we have high uv almost all year long. How much uv do you get inside the house? Does it depend how close you are to the windows? Also, if you wear glasses with uv protection, does the uv come in the side of the glasses where your eyes are not covered- thanks in advanceUV UVA UVB rays in home house- problem?
If you are shaded from the sun by a house wall or roof, you will be protected from solar UV. If you are standing inside a single pane window through which sunlight is falling on you, you will get nearly 70% of the UV that you would if you were outside.





Ordinary clear window glass lets in about 70% of the sun's UV radiation.So-called ';low-e'; clear window glass transmits about one quarter of the solar UV. There are special glazing products that cut the UV down to nearly zero. One example is called ';Heat Mirror with XUV';, which you can look up on the Web along with many other approaches to reducing UV incidence.





Yes, UV radiation can come in the side of your sunglasses. If the sun is shining on you from any angle, you are getting the UV component. However, sunlight coming in from the side of your sunglasses is not likely to shine directly into your eyes, so there will not be as large an effect. If this is an issue, get ';wraparound'; sunglasses, or a pair with side shields. Also wear a big brim hat or a sunshade.UV UVA UVB rays in home house- problem?
Ultra violet radiation is a problem for Floridians and I would recommend avoiding the sun for long periods of time and using a high SPF sunblock. Incoming solar radiation comes primarily from the sun by short wave radiation, so it will penetrate glass and you can get burned standing next to a window. In fact, like a magnifying glass the effects of standing next to a window can be amplified.





Short wave radiation is very intense invisible light.





Protection of the eyes is critical too, because the sun can cause irreperable damage there too.
some uv safer than others


uva 320-400 um safest


uvb 280-320 um moderate


uvc below 280 um unsafe





prolonged exposure to uv lower the immunity, dna mutated and caused skin cancers.





indoor window glass blocks 90% of uv below 300 um. so in any case indoor is safer
