Not all Polarization  and UV Protections is Treated Equally!  Know the  facts.


So many terms are thrown around about sunglasses, that the thought of buying a pair can be a bit overwhelming.  It is an investment to purchase a good quality pair so one should know the facts because not all UV, not all polarized are treated equal.

The question stands....What is polarization and why do I need it?

Polarized lenses are the only thing on the market that protects your eyes against damaging glare.  It is the glare off of the surface that goes directly into your eyes.  But know your facts before buying and know what you are protecting against. 

Polarized lenses is the only lens that protects against dangerous surface glare

Sunlight reflects off of  water, snow or flat roads and creates glare- which is  dangerous. Blinding sun glare can cause accidents.  A good quality polarized sunglasses are made with a filter, much like a filter in a camera.  The filter is embedded into the lenses and cannot be rubbed off, like sun tan lotion can.  Many polarized lenses, like  the kind that are bought in drug stores and department stores are made with a film of polarization that is applied like a band aid.  A band aid comes off with exposure to wind, water and external elements.  Much like a band aid , this is what happens to the polarized lenses that are applied with a film.  When this polarized film is exposed to elements, it  no longer is protecting your eyes and the UV protection on the film is not of good quality.  The film that is put onto these lenses also creates a darker lens which does not mean better coverage, it actually can do more damage to the eye.  As the eye is exposed to a dark lens, the pupil opens up, much like it does in the dark and when the pupil opens up, you have now exposed your eye to damaging UV rays.  So the protection that you thought you were buying is actually causing more health issues to your eyes. 

 Long term exposure to sun glare has been known to cause cataracts and has been directly linked to Macular Degeneration, which causes blindness.  Take your health of your eyes serious and know your facts about polarization.  

Here are the facts:

  1. A virtually invisible filter can be built into lenses to eliminate the amount of reflecting light that enters the eye. Polarized lenses not only reduce glare, they make images appear sharper and clearer, increasing visual clarity and comfort. Available for prescription and non-prescription sunglasses, polarized lenses can be worn indoors by light-sensitive people, including post-cataract surgery patients and those continually exposed to bright sunlight through windows.

    Most polarized sunglasses provide UV protection which is important to maintaining healthy eye sight. Just as we put on sunscreen to protect our skin, it’s critical that we protect our eyes from UV rays too.

    Look for sunglasses that block 99% or 100% of all UV light. UV absorption up to 400nm is equal to 100% UV absorption.  Do not purchase polarization applied by a film application
  2. Lens color and degree of darkness provide no indication of UV protection
  3. Larger frames, wraparound and closer fittingstyles provide better protection from stray light
  4. A higher price tag doesn’t guarantee quality. Cheaper sunglasses can offer superior eye protection over expensive counterparts as long as the polarization is a filter within the lens.  Much like our Sunclouds at Omni Eye Specialists that you can get for a great price!
  5. Polarized lenses help cut glare, but do not add sun protection
  6. If your sunglasses are old, ask your optician to test their UV protection.
