Are No-Line Bi-Focal Sunglasses Polarized

No-line bifocal polarized sunglasses are an amazing and sensible pairing of aesthetics and functionality. This is perfect for individuals who are having a hard time seeing objects that are too close and objects that are far.

Instead of constantly switching between glasses based on your activity, no-line bifocals feature split but invisible lenses that facilitate both distance vision and reading vision.

To appreciate this accessory, let’s take a look at how no-line bifocal polarized sunglasses work.

What are No-line Bifocal Sunglasses?

No line-bifocal sunglasses, also known as progressive lenses, are an innovative solution for those who suffer from a diminished ability to focus on objects at close-up as a result of ageing.

No-line bifocal lenses are specifically made for people diagnosed with presbyopia or sudden loss of visual acuity. This condition typically develops in adults 40 years of age and older.

Eye specialists prescribe no-line bifocal lenses to eliminate the need of using two pairs of glasses - one for distance vision and one for reading purposes.

Progressive lenses provide a smooth adjustment from distance vision through intermediate vision to near vision. The necessary adjustments and corrections are supplied between all these points.

Simply put, instead of having two different viewing zones that are typical of traditional bifocals, no-line bifocals feature progressive correction powers, hence easing issues like eye strain to provide you with a vision correction naturally.

What are Polarized Sunglasses?

Polarized sunglasses are commonplace among people who always perform activities near bodies of water. Polarized lenses effectively block glare from the light reflecting off the water’s surface and do a better job than any other type of sunglasses.

It is best to keep in mind that polarized sunglasses are not only recommended for people who love water-bound activities, but they may also be worn for routine outdoor activities.

They are especially useful when driving since they are effective in reducing glare and reflections from flat surfaces, such as hoods of the cars and the pavement.

People who deal with light sensitivity issues or those who recently underwent cataract surgery will find it advantageous to wear polarized sunglasses, too.

How do you Adjust to No-line Bifocal Lenses?

Adjust to No-line Bifocal Lenses

First-time users of no-line bifocal lenses or progressive lenses will go through a short period of adjustment before they can get used to using them on a daily basis.

It is important to remember that non-line bifocals will change the peripheral vision as a result of power changes that develop at the edges of the lenses. When this happens, you are required to implement slight movements in the horizontal eye and head movements.

This issue will diminish and disappear over time once you get fully-accustomed with no-line bifocal polarized sunglasses.

Below are some pointers that will help you adjust to the use of no-line bifocal quicker and comfortably, too:

  • Refrain from wearing your glasses immediately.
  • Wear new glasses continuously throughout the day.
  • Place your glasses high on the bridge of your nose and as close to your face as possible.

It is a commonplace for first-time wearers of no-line bifocals to experience some issues, but they all disappear after a short adjustment period. These concerns may also be managed with a few changes of head and eye movements while wearing your sunglasses.

Here are the common problems associated with first-time use of no-line bifocal polarized sunglasses:

  • Dizziness

If you are a new wearer of progressive sunglasses, you will most likely feel dizziness and vertigo, ranging from mild to severe. In a no-line bifocal lens, multiple powers are integrated into one compact lens. Dizziness is usually caused by looking through the wrong region of your lens.

Swim is a term that refers to the seasick sensation that you may experience when moving with no-line bifocals on. You can remedy this by merely changing the way you shift your vision from one zone to another. This may also reduce the seasick sensation that you initially feel with new no-line bifocals.

It is important that you find the “sweet spot” of lens correction, but this will take a little bit of time and patience on your part. This will also come naturally over time. You may also try pointing your nose or chin at the intended object instead of relying on your eye’s natural movement to reduce dizziness and vertigo.

  • Depth Perception Issues

Your depth perception will be a bit off during the first few times of wearing no-line bifocals. You will notice that going up and down the stairs or stepping off the curb will be challenging.

Your natural instinct to look down while using the stairs will be an issue, as the correction in the bottom portion of the lens is not necessarily suitable for the distance between the floor and your eyes. This will also make you feel that your legs have magically grown or that the ground is in a different depth than you’re accustomed to.

In case you always trip and stumble while wearing your new no-line bifocals, you need to be patient and take your time during movement. Use extreme caution when walking and taking the stairs until your vision has completely adjusted.

It is also encouraged to wear your sunglasses while sitting down and then slowly walk or use the stairs. You need to train yourself to look through the correct part of the lens for distance vision instead of looking through the reading part of the lens.

  • Headaches

Your eyes and brain will require some time to get accustomed to your new no-line bifocals, so expect headache attacks during the acclimation period. If you notice an increase in the frequency of headaches while wearing your sunglasses or if your headaches are getting worse, you may be suffering from eye strain.

In this case, it is best to contact your eye doctor, so they can suggest a prescription for your headache, as well as lens replacement.

These are just some of the quick-fix solutions that you can do to successfully transition to wearing no-line bifocal polarized sunglasses. Seek professional help if these remedies do not help you in managing the problems.
