To keep up with the increasing demands of the consumers, the eyewear industry has come up with innovative methods and has done really well. When the demand rose for thinner and lighter lenses, among the people who had high power measurements, thin lenses were introduced to meet the demands.
What are Thin Lenses?
Before talking about thin lenses, it’s imperative that we understand refractive index. In scientific terms, the refractive index of a medium is the ratio of velocity of light rays in that medium to velocity of light rays in vacuum. It is a measurement of the bending of light rays (refraction), when it passes from one medium to another. The higher the index, the more the refraction.
It also needs to be understood that eyeglasses correct our vision by applying the principle of refraction of light, ie., by bending light rays from its normal path of passage. The higher the lens prescription, the more the required refraction or bending.
So how do thin lenses come into the picture? Every material has a specific refractive index. Keeping the lens material constant, if we need to achieve a higher refraction, it can only be made possible by increasing the thickness of the lens. What if we change the material itself? By opting for a material with a relatively higher refractive index, we can actually reduce the thickness of the lens. This is how thin lenses have become a reality.
Basically, thin lenses are lenses made of materials with a high refractive index. Hence, it also gets i
Advantages of Thin Lenses
Thin lenses are not only one of the finest innovations of the eyewear industry but also one that has made wearing eyeglasses more comfortable. Here are its advantages.
Thinner - This is probably the USP of these lenses. By making the lens thinner, the visual appeal improves big time as the profile appears more slimmer with thin edges. Further, thinner lenses also make your eyes more visible to others, allowing you to make solid eye contact.
Lighter - Choosing thinner lenses automatically cuts down the weight of the lenses as less material would be required. Hence, if you need to shed some weight off your glasses and make a shift to a pair that is lightweight, thin lenses are your way to go.
Who Needs Thin Lenses?
Anyone who has a high lens prescription, your general lenses may be causing discomfort. You can make a switch to thin lenses for an added comfort. It not only feels light and easygoing but also enhances your physical appearance.
For those who require to put on glasses for a significant portion of the day, applying thin lenses to them can go a long way in avoiding any problem that you might face due to your glasses.
Thin lenses are ideal for those who wear varifocals as the varifocals are generally thicker than the other glasses types.
Are Thin Lenses Expensive?
With technological advancements made in the transition to thin lenses, the price of thin lenses are slightly higher than its other counterparts. But with the amazing benefits that it provides, an investment in thin lenses is totally worth it. Further, if you need to upgrade your varifocals glasses with thin lenses, you can go ahead as there are many online sites where cheap varifocal glasses are available.
