What are zero power glasses?

Zero power glasses also known as Plano Spectacles are spectacles with no corrective power.  These are widely used as protective glasses to shield the eyes from wind and dust.  People with contact lenses often use them for additional protection over contact lenses when they go outdoors.  People with eye dryness issues are advised to use zero power glasses, if they do not have spectacle power, to protect from the wind and air-condition blast worsening the dryness.

Two-wheeler riders use zero power glasses as protective eyeglasses, especially at night when they cannot use sunglasses.   Stylish people and celebrities often use zero power spectacles as accessories to complete a look.  Some professionals use zero power spectacles to create a sophisticated or geeky look for themselves.  Hence, zero power glasses have been around for a long time and have diverse functions.

Zero powered glasses with special anti-reflection treatments that filter electro-magnetic rays and blue light from digital devices are also referred to as computer glasses. These glasses are different from prescription glasses since they have no power. Computer glasses with zero power glasses are believed to reduce the digital eye strain.  Hence, these are very popular among youngsters who spend long hours on digital devices and IT professionals.  However, this is more of a myth created by irresponsible marketing.  Just having spectacles with blue filtering properties does not actually do anything to relieve eye-strain or reduce eye-fatigue.

We have discussed the true science behind the blue filtering spectacles in a separate blog.  For true relief from digital eye-strain or eye fatigue from any activity that is done continuously for a long time at near (about 1-3 feet) distance, we need Anti-fatigue spectacles.  

These spectacles have lenses that have a power booster zone.  Due to this booster, the eyes feel comparatively less tired after working at near continuously for long hours.  If at all there are any glasses that qualify as true computer vision glasses, then it is this category of spectacles.

Most international brands like Essilor, Zeiss, Nikon and others make these special lenses.  The same principle is also incorporated in contact lenses by Cooper Vision.  

Next time you are in for a vision consultation, do make it a point to discuss this with the Optometrists at R. Kumar.  The optometrists will also demonstrate to you with a simple device how the anti-fatigue lenses will benefit you.

Computer glasses, with anti-fatigue boosters, are beneficial in reducing the eye strain that you may feel after prolonged hours of screen time. In various cases, it is also suggested to people with watery or tired eyes because of excessive screen time. It helps mitigate the issue.   

Types of zero power glasses?

Computer glasses come in multiple formats, so before you buy any, it's important to see the ones that fit your specific needs. So, let’s check out the different types of computer glasses: -

  1. Computer glasses with blue filter 

The surfaces of Computer glasses are processed with special anti-reflection treatment that filters blue rays emitted from digital screens. However, such superficial treatment based lenses are now an out-dated product.  The new age blue filtering lenses have blue filtering properties incorporated in the monomer of the lens material itself.  These zero power glasses can be used by anyone. These computer glasses are available at R Kumar Opticians.

There are many other benefits of zero power glasses, including glare reduction, prevention against vision conditions, and many others. Let’s discuss the benefits of wearing powerless glasses in the next section.

Benefits of wearing zero power glasses

  1. Shield Eyes from Dust 

Zero Powered spectacles act as physical shields from dust, smoke and environmental pollutants.  In places with poor air quality, such glasses can help prevent irritation of eyes.  They are a necessity for two-wheeler riders at night when it is not feasible to use sunglasses.  Contact Lens users can benefit from these as additional protection over contact lenses when going out.

  1. Protection from Wind

Zero power spectacles blocks a majority of wind.  Wind dries the surface of the eyes.  As a result of the eyes feel dry, itchy and they water.  Many people develop dryness due to continuous exposure to air-conditioning blast on the face.  Also, you may have noticed the same while driving, if the AC is directly on the face or when you are driving with the windows open, the eyes water slightly.  Zero powered or Plano spectacles are helpful in these situations.

  1. Style Statement and Change in Appearance

Since times immemorial, you would have seen stylists pairing the right eyewear to complete a look.  Actors have effectively used zero powered spectacles to create the right look for a charter they are portraying.  Celebrities, Infulencers use zero powered spectacles creatively in their content.  In fact the most popular snapchat filters are the ones with spectacles.  In the professional world, various people use spectacles to curate their look from sophisticated to serious and geeky.  

  1. Reduce eye strain

Zero powered spectacles with anti-fatigue properties and blue light filtration can help relieve eye-fatigue caused by continuous computer use and desk work and also strain caused by prolonged use of digital devices.

  1. Prevent frequent eye-infections, especially in children

This may come as a surprise, but it's a proven tactic especially for young kids.  We often touch un-sanitised surfaces and invariably touch our eyes, or rub them when we feel tired.  This is instinctive, not intentional.  In some people, this leads to recurrent low grade infection. It causes unnecessary irritation.  With zero power spectacles, the hands are literally restricted from touching the eyelids.  Hence, such unwanted infections can be prevented. 

Conclusion

Hence, you see how zero powered or plano spectacles can help in so many different ways. Therefore, by purchasing a pair of zero-power glasses from a reliable optician like R Kumar Opticians, you can protect your eyes from these conditions. Furthermore, computer glasses can reduce screen glare to an extent because they come with anti-reflective and slightly tinted glasses.
