Progressive lenses marked a new stage in correcting vision. For the first time, spectacle wearers had a solution that allowed viewing items at different distances. Yet, comfort and adaptability are still a challenge for many.
This is especially true if you require different prescriptions for each eye, which may lead to discomfort using progressive lenses. For a variety of reasons, most notably comfort and adaptation, you may have avoided the switch from single vision or bifocals to progressive lenses.
Binocular Harmonization Technology (BHT) offers a new breakthrough for progressive wearers fighting discomfort caused by differing prescriptions for each lens. We’ll break down what this technology does, and why you should be making the switch below.
Correct for Different Prescriptions
Different prescriptions in each progressive lens creates a challenge.
According to our internal data from European progressive lenses ordered between 2007 and 2013, 70 percent of progressive users have different prescriptions in each eye.
We’ve created BHT as a solution to this challenge. BHT is a new innovative solution that considers the prescription for the right and the left eye as individual components to calculate the optimal binocular lens design, ensuring that the power distribution and progressive corridor length of each lens is exactly what the eye needs.
Binocular Harmonization Technology
BHT makes your progressive lenses more comfortable if you have different prescriptions for each lens. It works with small and large differences and strong or weak corrections. It helps you read longer, spend more time on digital devices, and feel less strain when changing your focus from near to far over and over.
BHT specifically helps alleviate strain and discomfort, which can be experienced in a variety of ways including:
- Headaches
- Difficulty focusing or changing from far objects to close ones
- Blurred or double vision
- Dry eyes
- Fatigued eyes, burning, sore, or tired eyes
These symptoms can be caused by a variety of things, like the wrong prescription or wrong type of the spectacle lens, usage of digital devices, or long focus intensive near work activities, such as long reading. Your Eye Care Professional can help you determine where these symptoms are coming from before you make any decisions.
So how does BHT work? BHT takes into consideration the prescription for both eyes to create your glasses. By adjusting the lens design, we ensure both eyes have balanced proper support to make your eyes comfortable anywhere you look. Because your eyes are now working perfectly together, you’ll be able to use more of your progressive lenses in comfort.
Is BHT Right for You?
You are probably asking yourself if BHT is right for you, and how you go about getting it.
The first thing to note is that this technology is for presbyopes, for people who are wearing progressive lenses. You might not be familiar with that term.Presbyopia happens to us all around the age of 40, and we often experience this as it becomes very difficult to read, and we require reading glasses. You also need to have different prescriptions in each eye, also known as anisometropia.
The most important thing to do is to consult with your Eye Care Professionals. They’ll be able to work with you to determine whether BHT applies to you and what your lens options are. BHT works with a variety of premium progressive lenses, and you should discuss your options and personalisations to your lifestyle.
Your Eye Care Professional will be able to take into account your vision needs, prescription, lifestyle, and any additional considerations when helping you pick the right glasses for you. As progressive technology has improved, higher-quality lenses can be greatly adapted to how you spend your time.
