One of the main reasons behind visiting the optician is to get the perfect pair of glasses.
It is also incredibly important to get the correct type of lens according to our needs. There are a huge number of different types of lenses available in the market today. Some are specifically made for kids while others are made for people with reading difficulties after a certain age. The important thing is to recognize the need and then go ahead and fulfill it.
Types of Lenses
- Polycarbonate lenses for example are great for children. Many a times while playing or any other physical activity children tend to drop and break the lens of their glasses. With polycarbonate lenses the chances of this happening are cut down dramatically. These lenses are built in such a way that they can withstand a certain amount of impact and do not break easily. These lenses are great for adults who have jobs which require them to be in an active environment, even sportspersons as well. These lenses cannot get scratched easily as well. Another great thing about these lenses is that they offer great ultraviolet protection. This means that the eyesight will not be damaged by ultra violet exposure emanating from the sun.
- Trivex lenses are pretty similar to polycarbonate lenses when it comes to the future but in reality they are a better version of polycarbonate lenses. Trivex lenses are made of plastic which is scratch resistant and hard to break up to a certain extent. At the same time these lenses are far lighter than polycarbonate lenses and resultantly pretty thinner as well. Certain studies have also shown that trivex lenses have a better impact when it comes to vision correction in some people when compared with polycarbonate lenses. This means that the trivex lens is better than the polycarbonate lenses in many ways.
- High index plastic lenses are made to fulfill the needs of people who have to use a higher power lens in order to correct their vision. Many people are seen wearing glasses with extremely thick lenses. High index plastic lenses are a great substitute to these thick lenses as they do the job of the thick lenses but are not that “stone age”.
- Aspheric lenses are totally different than any other lenses available. The major difference between these lenses and others is that these lenses are not spherical in shape. As they are not spherical in shape these lenses can be given a different curvature which in turn makes this lens much thinner and to a certain extent flatter than its contemporaries. This also means that the usable portion of the lens increases dramatically.
- Photochromic lenses are great for people who have to work in the sunlight as well as in the office from time to time for example Engineers etc. These lenses change from being clear to tinted as soon as they are exposed to sunlight. Thus, people will not need to buy and use prescription sunglasses.
