lenses in the eyewear industry

When we look for the advancements in the eyewear industry, it is all about cases of eye health developments that have succeeded to great heights. There have been many challenges and discoveries that have been faced throughout the year. There have been perfect breakthroughs as well to improve the overall eye health industry and that has definitely made progress in the department. 

But how do these developments in the eyewear industry prove to be an integral part of the current world? Yes, the developments have proved to be a way to make life much simpler and easier and that is exactly what the eyewear industry has always aimed for.

Advancements in lens technology

We frequently discuss the numerous frame forms and fashions that have been launched, but what about the lenses? There are many other types of glass frame styles to discover, including cat-eye and aviator frames. These apply to lenses as well and are the same, just like you might try to buy reading glasses for women. And we’ll talk about all you need to know to locate the ideal lenses for your needs.

Let’s get going:

Varifocal lenses

Although many people still use bifocal lenses, varifocal lenses are a considerably more sophisticated type of lens. In contrast to bifocal lenses, which only have two, varifocal lenses feature three different focal lengths. This lens is ideal for people who struggle with both near and farsightedness since it has three refractive zones: close, far, and intermediate.

The absence of an apparent distinction between the refractive zones is the best feature of these lenses, so might look on to buy varifocal glasses. You must have observed that in bifocal lenses, the near and far refractive zones are clearly separated, making eye movement much more challenging.

With varifocals, there is no such distinction, making it extremely challenging for the eye to transition from one zone to the next.

Despite the fact that wearing varifocal lenses has many advantages, there is a challenge that first-time users of varifocal lenses face.

What’s the issue and how to tackle it easily? 

Because varifocal lenses include three refractive zones, maintaining continuous vision can be challenging and perplexing for first-time users. While transitioning from one zone to another, the brain and eyes become confused.

Here are a few recommendations that one should take into account before converting to varifocal lenses:

  • Consistency is the most important thing to remember, period.
  • If someone wears their glasses all day and all night, they shouldn’t take a break in between.
  • While wearing varifocal glasses, it’s also vital to remember that switching back to regular glasses will prevent the eye from having the necessary time to adjust.
  • To prevent becoming dizzy, keep your eyes from moving quickly and tilt your head in the direction you want to go.

One should speak with a doctor if they experience extreme dizziness and are unable to adapt to changes in the refractive zones even after trying out all of these techniques.

Thin lenses

Recall the high prescription situation where one converted to thick frame lenses giving it a bug eye or fish bowl appearance? These have been replaced by thin lenses and ultra-thin lenses as a result of technological improvement and other modifications and developments.

The high index lenses with many more refractive pairs than usual are thin lenses. If more light is refracted, one of your normal lenses needs to be thicker. Ultra-thin lenses are 30% thinner than standard prescription lenses, while thin lenses are 20% thinner than regular glasses.

Transition lenses

Want to see a magic trick? If so, transition lenses are the way to go. These eyeglasses are the ideal illustration of how the eyewear business has advanced technologically. When worn indoors, these just function as conventional prescription glasses. However, when worn outside, a black tint covers the lenses, giving the appearance of sunglasses.

These colours have the capacity to modify themselves in response to the amount of direct sunshine. Darker hue results from more sunlight, and vice versa. The best thing about these lenses is that you may prevent any kind of confusion and do not need to have two pairs of glasses. Additionally, they can shield the eye from UV radiation and offer the best defence.

Tinted lenses 

Yes, this is the type of lens we prefer, and you can opt to have the colour added. Additionally, one can have their lenses reglazed with the preferred shade. giving exactly the same as what the sunglasses were giving. Your tinted lens does not have to be as dark as that of the sunglasses, it is as supportive as that of vision correction glasses and even prevents UV rays.
