The technology of eyewear in Cape Cod is constantly changing and improving—the latest technology from last year might be completely outdated in just a few months as optometrists and optical researchers come up with new and exciting ways to assist lens-wearers with their eyesight. One of the technologies that is expected to be very popular in 2018 is called free-form (or high-definition) lenses.
Free-form lenses are created using highly specialized computer software that aids lens-creating equipment in manufacturing high-definition lenses that can sharpen your vision and help reduce glare. Lens wearers of all types, whether they are nearsighted, farsighted, have an astigmatism or require progressive lenses, can benefit from upgrading to free-form lenses.
What free-form lenses do
Free-form lenses are designed using a digital manufacturing process that uses computer-based design and computer-controlled surfacing equipment that is far more precise than equipment used for traditional lenses. This process results in a superior lens customized for your eyewear prescription and frames and mitigates optical aberrations found in traditional lenses.
Traditional lenses are sometimes affected by particular characteristics of your eye shape or surface or by standard lens limitations. This can cause your vision to become less clear, even if your prescription gives you 20/20 eyesight. With their highly specialized production, free-form lenses help to remove those issues, providing you with numerous vision benefits:
- Generally clearer vision: In general, free-form lenses are known to improve the wearer’s visual clarity and to drastically sharpen vision. This improves contrast perception and can make lens-wearing a clearer, more pleasant experience.
- Less glare at night: At night, light sources like car headlights can sometimes cause glare or halo effects for lens-wearers. Free-form lenses drastically reduce the effects of glare at nighttime.
- Better color vision: Free-form lenses can improve the intensity and brightness of colors.
Free-form lenses are particularly good for wearers with complex or high prescriptions or progressive lenses, although anyone who owns eyewear in Cape Cod can benefit from the extra definition they provide.
How to get free-form lenses
When you go in for an eye exam, ask your practitioner about free-form lenses. To get all the information necessary for production, the optometrist will scan your eyes with highly specialized equipment that collects data points. This data will help the computer software identify your proper prescription and note variations in your eye shape and surface that require attention when creating the lens.
Next, you will select your frames, and the optometrist will take more measurements with the frames on your face to see how close they sit to your eyes, the position of your pupil in between the frames and more.
All of this information will come into play at the lab where the free-form lenses are manufactured. The data will be entered into the computer software, which will direct the free-form generator to create your customized high-definition lenses.
It’s important to note that these free-form lenses may cost up to 25 or 30 percent more than your traditional lenses; however, the improvement you will see in your vision is more than worth the additional costs.
