With so many different types of lenses available today, it is really important to ask an optician for advice when choosing sunglasses. Not all the sunglasses are made equal and for this reason, it is important that you choose something that suits your needs and requirements. There are different types of lenses and all of them help to see differently in certain conditions. If you are considering buying sunglasses, given below are some of the different types of lenses and their functions that can help you make the right choice.
Polarized lenses – polarized lenses cut reflected glare and are quite popular among those who play snow and water sports. Polarized lenses reduce glare which are caused by light that is reflected off the surface of the sunglasses.
Blue blockers – these types of lenses block blue light as it is believed that blue light can be harmful to the eyes and may cause diseases such as cataracts and macular degeneration. Sunglasses which have blue blockers have amber lenses and are quite common among boaters, pilots, skiers, etc.
Mirror coated lenses – these types of special lenses limit the amount of light that enters your eyes. Sunglasses which have mirror coated lenses are really comfortable and are great when taking part in activities under bright conditions.
Gradient lenses – these lenses are shaded from the top to the bottom and the top part is the one which is the darkest. These lenses are great for driving as they protect the eyes from the sunlight. Since the lower part of the glasses is less tinted, they allow more light so drivers could see their dashboard clearly.
Double gradient lenses – these lenses are tinted from the bottom to the top but the difference is that it is only the middle part which has a lighter tint. The bottom part of the sunglasses and the top has the darkest tint and protect the eyes from overhead sunlight.
Photochromic lenses – these are special type of lenses that adjust their level of darkness depending on the amount of ultra violent light which the wearer is exposed to.
Different types of lenses offer different benefits and it is important for you to decide for what purpose you are purchasing the sunglasses for. If you are just looking for protection from the sun, you can go for polarized sunglasses, but if you are a sportsperson, you may need to look for more in the pair of sunglasses that you are purchasing.
