Light damage is light like lights in a city.
The solar filter is used when you are observing the sun, because if you look directly at the telescope, you will be blind.
-
The main purpose of the light damage filter is to observe deep-sky objects such as nebulae, and the visual effect of small-aperture refractors may be smaller.
I heard that the UHC filter of the Seven brand is a good drop, and it is relatively easy to accept.
Pay attention to the size, there are two specifications, and 2 inches.

The full range of eyewear is impact-resistant and UV light (as well as clear lenses) to protect dentists and technicians' eyes from intense light damage at work.
Anti-fog goggles with 100% anti-fog effect.
1.It can be sterilized at high temperature 135. (Except for anti-fog type).
2.Complies with CE EN166 - Impact Test.
3.The polarization angle tolerance is less than 3 degrees. (Most glasses have a tolerance of 6 degrees)4The large size design can be worn alone, and it is also suitable for glasses wearers.
5.The yellow lenses provide a sharp contrast with 100% filtering of ultraviolet light.
Teeth whitening and cavities require a 430 490nm wavelength and 600mw C ultraviolet light device, which can seriously damage everyone's eyes!
Most dentists use red goggles to protect their eyes, but red goggles leave only 14% of the visibility rate.
It can be anti-fog, anti-impact, anti-wind and sand, anti-splash, anti-ultraviolet, and light-loving curing lamp.

I've been wearing it for 2 months now and I think it's very good. The former promotes blood circulation with the effect of ochre titanium, and the latter double 95 is the negative oxygen ion effect of the negative ion frame of 1800 m to promote blood circulation, which is an upgrade of ochre titanium! It is more suitable for overuse of eyes and middle-aged and elderly people.
My mother is quite satisfied with wearing it, the most important thing is that you can feel the obvious effect at one time, and at the same time I bought my mother Jie Eye newiseye anti-light damage double 95 negative ion goggles, my mother brings it every day, the glasses are not dry, the symptoms of floaters have disappeared significantly, the effect is more obvious and effective than the previous **, it is very convenient and comfortable, economical and cost-effective, so I will choose Jie Eye in the future.

Photovoltaic power generation solar panels do not produce radiation. But light pollution from photovoltaic solar panels has the potential to have health effects.
Photovoltaic solar power generation, the principle is that light energy is directly converted into electrical energy, the advantage is that solar energy can be used everywhere, can be supplied nearby, the disadvantage is that it is still relatively expensive. Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photogenerated volt effect at the semiconductor interface. The key element of this technology is the solar cell.
Solar cells can be encapsulated and protected in series to form large-area solar cell modules. Flat panel solar cell modules are photovoltaic solar panels.
Photovoltaic power generation solar panels do not produce radiation. But light pollution from photovoltaic solar panels has the potential to have health effects.
Light pollution is a new source of environmental pollution after waste gas, waste water, waste residue and noise, which mainly includes white light pollution, artificial daytime pollution and colored light pollution. Light pollution is threatening people's health. In daily life, most of the common light pollution conditions are the dizziness of pedestrians and drivers caused by the reflection of mirrored buildings, and the discomfort caused by unreasonable lighting at night.
At present, there is no clear basis and conclusion on the impact of light pollution on health, let alone relevant evaluation standards. However, some studies believe that light pollution has the potential to damage the eyes, induce diseases, and affect people's mood.
It is thought that light damage may cause headaches, fatigue, decreased sexual performance, increased stress and anxiety. Animal model studies have demonstrated that when light is unavoidable, it can adversely affect mood and anxiety.
The light damage of photovoltaic power generation solar panels is easy to avoid, choose low-reflection photovoltaic power generation solar panels, adjust the reflection of photovoltaic power generation solar panels to no one area, block the reflection, and pay attention to the installation of sunglasses can be avoided.
The sun is hot. The moon is cold!
Generally speaking, the word "account" can also be used for currency, but the word "account" must be used for textiles. Beg.
Hello! Hopefully, the following will be helpful to you.
Optical broadband is the broadband of optical fiber access, if you can use this access method in your location, it is recommended that you install optical fiber broadband, it will be much more convenient to upgrade in the future, optical fiber allows access to higher bandwidth, such as 50m or even 100m, ordinary ADSL broadband can only access up to 8m (if you use broadband below 8m, the effect of the two access methods is the same). You can handle broadband business in Anhui Telecom's online business hall, and you can enjoy more discounts in the network hall! >>>More
X-ray, CT and MRI are all imaging methods, but also the main basis for diagnosing orthopedic diseases, many people do not understand their differences, only know that there is a high and low distinction in the **, people who do not understand the situation usually ask to check a cheaper X-ray when seeing a doctor, and feel that the effect is the same. In fact, they are so different in **, it is enough to show that there is a big difference between them, but not the more expensive the better, the focus of different examination methods is different, take cervical spine diseases as an example, X-ray, CT and MRI can not detect the lesions. What is the difference between X-ray, CT, and MRI? >>>More
