Polarised Lenses



The best solution for sun protection and driving is polarised lenses.

Most optometrists recommend that everyone should own a pair of quality polarised sunglasses. Polarised lenses do what no other lens treatment, tint, or photochromic lens can - they block blinding glare. In addition, polarised lenses can enhance visual acuity, colour contrast and comfort and block 100% of harmful UVA (315-380nm) and UVB (280-315nm) light. You will see more comfortably while taking care of the health of your eyes. 

There is much demand for polarised lenses - in fact, without really knowing much about what they are or what they do, many people seem quite prepared to insist on having polarised lenses over ordinary tinted lenses (if given a choice). 

But, what do polarised lenses actually do? How do they work to make the wearer see more comfortably?
The answer is simple: polarised lenses ease the discomfort of blinding glare.

What exactly is glare, and what causes it?
Glare is uncomfortable visible light that compromises one's vision.

Light travels from the sun in the form of waves to earth. Once these waves hit a reflective horizontal surface (such as a road or a body of water), they change their energy and become scattered. At this moment of reflection, light becomes polarised and forms ‘visual noise’. This is known as ‘blinding glare’, interfering with the actual image. The only way to eliminate this glare is to place a polarised lens in its path to absorb the interfering glare. By neutralising glare, polarised lenses help one see objects more clearly, and more comfortably and also help to reduce the harmful effects of UV light.

This fundamental principle has resulted in the creation of polarised eyewear.

Polarised lenses are coated with a particular chemical film that helps to reduce glare. The most crucial element of any polarised lens is the polariser – a unique film incorporated into the lens structure.

Are Polarised lenses worth it?
Glare is unpleasant, but it also impairs depth perception, distorts your view and colours, and can cause temporary blindness. So the additional cost is worth it — especially for athletes. Regular sunglasses may filter some sunlight, but they do not eliminate glare as effectively as polarised lenses.

A polarised lens offers the following advantages over non-polarised lenses:
- Polarised lenses increase visual comfort. Since your eyes don't constantly challenge glare, it is easier to view objects in bright conditions.
- Polarised lenses enhance the clarity of vision and contrast for ground-level objects and surfaces and for seeing across the water.

The unique chemical composition of the polarising film facilitates a chemical reaction between the lens material and polarising film material. As a result, a stable chemical bond links the polarising film and the lens. This eliminates any chance of film separation.
