Researches show the possibility of damage to the eyes in different working spaces rises based on the exposure of the eyes to threatening materials, to prevent such catastrophic events one should utilize various types of safety goggles. Most of these accidents take place as a consequence of impacting materials in the eye or exposure of the eyes to chemical substances. Above all, there is always the possibility of damage at home, while working with electronic tools and other activities. Utilizing safety goggles at work will protect the eyes in addition to eradicating the possible medical expenses in case of any incidents. Herewith, we elaborate on different types of safety goggles and their usage based on their particular working space. 
Safety Glasses
By analyzing and distinguishing different types of safety goggles, we can conclude that this type of safety goggle is suitable for general usage and is mostly used for eyes protection against the materials, harmful radiation, or exposure of the eyes to chemical liquids.
Usage of Safety Glasses
As mentioned earlier, the most important role of safety goggle is to protect the eye. Safety glasses can be used in different professions such as welding, construction fields, working with heavy machines, factories and workshops, laboratories, blacksmith, and so on. Photochromic Glasses This type of glasses is designed to protect the eyes against UV and the color of the lenses changes according to the environment, in other words, the color of the lens turns dark in a bright atmosphere and the color turns to the normal mode in the dark places. So, there is no need to change the lenses in case of moving from one place to another. Warden Safety Goggles This type of safety goggle has a general usage in industry, construction, and gardening. These goggles' lenses cover a variety of colors. It is made of polycarbonate and has a slight weight for that end. In addition, a foam pad is placed on the nose that eases the use of this type of goggles. Safety Medical Goggles Doctors are constantly exposed to UV in clinics and their working places; thus, the use of safety goggles is obligatory. This type of goggles is made of polycarbonate with suitable durability and decreases irritating glows. The use of this type of goggles in forensic medicine is also notable, which eliminates irritating glows while working to have full concentration. 
Safety Goggles
Goggles are one of the personal protective equipment (PPE) that everybody can use in their working place. This type of glasses is used in the fields such as carpeting, construction, works associated with electricity, medical care, and other safety-related fields. Safety Visors Safety visors are another type of safety equipment mostly used for athletes. This type of utility are usually attached as a curvy surface connected to the person's cap to protect the eyes against the sunlight. NXT Goggles This type of goggles has more resistance against impacts and is less fragile, it has also lightweight, and contains more protection against sunlight. This type of glasses is more expensive compared to other types. Acrylic Safety Goggles This type of lightweight safety goggles has more resistance against the chemical solution. Acrylic goggles due to the low physical resistance and low visibility are not suitable for works that require a high level of delicacy. Safety Optical Goggles Optical goggles are resistant to scratches and they make no limits on the user's sight. Face Shield In addition to protecting the eyes, face shields are good protectors for the face. Some shields also contain glasses. And some shields are equipped with a protector part for the head. One of the usages of a face shield is for welding, protecting the face from the heat, sparks, and the harmful glow of welding. 
Different Types of Lenses for Goggles
There are different types of lenses used in the goggles that differentiate them according to the usage and the working space. The lenses for the goggles are made from plastic, polycarbonate, and glass. Herewith we elaborate on some types of lenses used in goggles. Clear Lens The clear lens is the most general one that is used in the working spaces with lower potential dangers, this type of lens has the most degree of sight among other lenses. These lenses are suitable when one seeks to distinguish the real colors in the environment. Clear lenses are made from polycarbonate which makes them more resistant compared to lenses made by glasses, this kind of lenses have the most transparency of light and are suitable for workplaces that are of low brightness. Polarized lenses Some sort of chemical substance is used in this type of lens which functions as a filter and removes some parts of the light before reflecting in the eye. Polarized lenses are suitable for outdoor working spaces. Polarized lenses protect the eyes by reducing the straight reflection of the sunlight. Blue Lenses Since blue color can be resistant to yellow color, blue lenses are more suitable in places with a high reflection of yellow light and radiation or exposed to sodium steam. Blue lenses neutralize the light caused by sodium steam and avoid potential damage to the eye. Orange Lenses This type of lens is mostly used in low-light places and assists the sight to see with more clarity. Usually for activities with high care and delicacy orange lenses are used. Green Lenses These lenses are usually used to protect the eyes against UV, Infrared, and heat. Another advantage of this type of lenses is the power of sight improvement in the working space. Here is the list of some standards which have been considered in our products:
- EN172 Standard: This standard is related to physical aspects of the products such as resistance to the impact
- EN170 Standard: This standard is related to UV protection
- EN169 Standard: This standard is related to wending circumstances, plasma cutting, and…
According to what we have discussed so far, the most important factors for choosing a goggle are quality and the standards. Of course, we should pay attention to every goggle and the lenses usage before taking any actions as we are about to take care of one of the most important parts of the body, the eyes.
