Clarity refers to the quality of clearness of an object,the clarity of picture frames tends to be reflected by the amount of light it lets through. Glass lets through on average 80% of light, and Plexiglass lets through around 90% of light. Although scratch resistant, Plexiglass is more prone to scratching than glass.
Photochromic lenses darken in 30–60 seconds on average when exposed to ultraviolet light. To clear, they take a bit longer: 2–3 minutes is normal. Scientists are still working with the photochromic dyes to quicken the reactivity of the lenses. In the future, we could see faster and faster activation and clearing times.
Every 4 hours and 20 seconds, the CrazyCap purifier switches on and shines a deep UV light onto the inside of the bottle. This sterilizes the surface and ensures the likes of mold, viruses and bacteria can’t build up in your bottle between uses. This product doesn’t require backwashing multiple times like some water bottle filters.
The UV light does not have a shut-off facility. Since the UV light is invisible, you cannot determine whether the unit is functioning. However, UV water purifiers have LED indicators to notify users. UV water purification requires pre-filtering to remove other contaminants. UV Water Purification – Frequently Asked Questions

It blocks up to 99% UV light and 69.7% blue light, and its anti-reflective surface also reduces glare and strain on the eyes. Moreover, it prevents hindrance and interruptions in the sleep cycle
Researchers at John Hopkins University discovered that disinfecting “high touch” public locations in hospitals, such as bed rails, tray tables, and vitals monitors with UV radiation, takes only 15 minutes. At a distance of six inches from the American Ultraviolet Germicidal Fixture lamp, It can kill an average bacterium in 10 seconds.
The exhibit should be designed to eliminate as much UV as possible. UV light can be avoided by selecting light sources that do not emit UV or adding UV-filters to existing light sources. Framed objects and display cases should use UV-filtering acrylic. Daylight should be reduced by positioning of the case and filtering.
Return to the place you bought them and ask about warranty or if they can remove the coating. They may not want to, but it is good to check first (usually charge is about $10-30 or sometimes free). 2. Send to an optical lab that will remove the coating for you (often costs about $30 dollars) 3.
A UV light kit will often include a flow control device (or one is purchased at a local plumbing supplier) that is installed at the inlet side of the fixture - a small disc that is inserted into the plumbing connection on the light fixture. The UV light water treatment system must be properly installed - at the right location in the water system.
Some UV filters act as UV screens absorbing the harmful UV light. They are opaque and protect both food as well as the packaging material. Other UV screens are based on organic compounds and act as ultraviolet degradation inhibitors (p.38,[1]). Apart from being used in polymer based materials, UV filters are added to printing inks.
Along with filtering the water, the LARQ Pitcher uses UV light to purify water once it has passed through the filter. LARQ claims this makes the product the "world's most innovative water pitcher

Plants also need some infrared (IR) light, on the opposite side of the spectrum from UV light. Exposure to adequate levels of far-red wavelengths can encourage blooming and healthy stem growth. However, too much infrared light can damage leaves, stems and flowers. Most window films filter out some infrared light, which we experience as heat.
