The sun’s radiation consists of UV or Ultraviolet rays which come in two types – UVA radiation and UVB radiation. These radiations are the reasons for many kinds of problems in human beings such as aging, photodamage, skin damage, and even skin cancer in many people.
Protecting the skin and vital organs from sunlight is one of the most important things for men and women especially in this age as the sun’s rays get harder and more damaging day by day.
The best method to protect the skin is to wear sunscreen and sunglasses to protect the eyes from damaging rays of the sun. Sunglasses are proven to cut out 99% of the harmful radiation that enters the eye through the damaging rays of the sun.
Sunglasses are mostly used as a fashion accessory by men and women due to mainstream media and celebrity influence but sunglasses serve a purpose beyond just fashion.
Sunglasses were invented to handle the damaging effects of the sun on the eyes and to help with vision disturbances in the day due to bright and glaring sunlight. It is also very useful when it comes to cutting out on excess light while driving as it can cause a temporary blinding effect and may lead to accidents and mishaps.
Types of Sunglasses
Sunglasses are of two types – UV sunglasses which are the basic kind of sunglasses that only remove the UV radiation. Polarised sunglasses come with an extra film of polarised material that helps in cutting out all the glare that is reflected off of shiny surfaces such as water, mirrors and snow, and glass.
UV Sunglasses are one of the standard types of glasses that have a UV film that helps in regulating the light that enters the glasses to the eyes. When sunlight enters the glasses, it is split into three parts, UVA radiation is the most penetrating and prevalent of all the light.
The second part is UVB rays which are less penetrating but prevalent in all of the sunlight. Both of these lights can enter and cause damage to the eye. The UV film on UV sunglasses removes and reflects away the UVA and UVB rays. It only lets the Visible light enter the glasses and provides for clearer and safer vision.
Polarised sunglasses are more expensive than UV sunglasses and come with an additional film of Polarised material on top of the normal sunglasses. This film is extremely useful as it helps in soothing the eye by eliminating the glare that bounces off of surfaces such as roads, glasses, snow, and water.
Glare is quite dangerous as it can blind the eye temporarily and cause vision impairment while driving or during sporting events. The polaroid film helps with:
- Visual Comfort for Strainfree vision
- Improves contrast and clarity of items
- Provides safety from glare
- Can help with identifying true colors
- Reduces reflection
Conclusion
These are some of the benefits of UV sunglasses and Polarized Sunglasses. Both these sunglasses are extremely useful but Polaroid sunglasses have an extra mile over their counterpart thanks to their additional benefits. Polarised sunglasses are used for sports such as cycling, motorcycle racing, car racing, skiing, mountaineering, and hiking, etc. They are also great for those who live in extreme sunlight and drive quite often in broad daylight. UV sunglasses may only be able to eliminate the harmful sun rays but polarised sunglasses can help in safe and comfortable vision.
