Minimise Glare With a Pair of Polarised Sunglasses
Polarised sunglasses are a great addition to any outfit and they offer protection from intense glare on sunny days. The special lens construction of polarised lenses allows only specific light waves to pass the filter, resulting in reduced glare. You can find a pair of polarised sunglasses from eBays large collection.Can any lens be polarized?
Yes, a wide variety of lenses can be polarized. People who permanently wear glasses may choose to opt for polarized lenses and experience the glare reduction properties while wearing their regular reading/working spectacles. It is, however, important to note that polarized glasses can make it difficult to read information on your cellphone or GPS, this is due to the amount of blue light that the lenses block.When do polarised sunglasses work best?
Although polarised sunglasses can be worn on an everyday basis they are specifically adept at reducing reflections from water. People who often participate in water sports activities can benefit a lot from wearing polarised lenses and protect their eyes from damage on bright days. Polarised glasses are also a good choice for driving and work well to counteract windscreen glare.What should be kept in mind when choosing a pair of polarised sunglasses?
Choosing the right pair of sunglasses can be tricky since there are quite a few factors that should be taken into consideration. Look out for these features to make your choice easier:
- Design: Start your quest by looking for a pair of sunglasses with a design/shape that fits your facial features. While a large pair of sunglasses may work well for one person, it can look less appealing on the next.
- Use: Take the way you will use the sunglasses into consideration. Sunglasses for use in sporting events should be tight fitting so that they stay firmly in place but sunglasses for everyday use cope well with a more relaxed fit.
- Construction material: Pay close attention to the frame of your glasses, if you are going to be using the glasses often it may be a good idea to opt for a stronger frame.
Polarised sunglasses were first invented by a Swiss optics engineer in 1937. The magic behind the lenses is quite simple - a laminated layer of glass disrupts the path of the light and allows only horizontal light waves to pass. Since glare is caused by vertical light waves the lenses virtually eliminate it from reaching your eyes. Because of the multiple layers of laminated glass, polaroid lenses have a distinct blue hue.
