Lens Options Explained

Lens Design (Standard vs Digital HD [High Definition] Design):

Optical lenses by nature, consist of multiple curved surfaces, which means there will always be some degree of light distortion around the periphery/sides of the lenses. The effects of light distortion become more pronounced for higher prescription powers and for goggles, glasses or sunglasses with more curved lenses (e.g. wrap-around sunglasses).

While Digital HD Designed lenses (regardless of lens material) will always result in clearer vision all-round, as a general rule however, you are likely to enjoy noticeable improvements by selecting these lenses as opposed to standard lenses if your required prescription is above Sphere (indicates near/farsight correction required) of +/-3.00 and Cyl (indicates astigmatism correction needed) of +/-1.50.  

 

Ultra-Thin/High Index Lenses:

Light weight/slimline, plastic optical lenses are generally recommended for casual wear and are not required unless the total prescription power for any one eye is greater than +/-8.0 (i.e. sum of sphere power and cylinder power > +/-8.0   -eg: sphere for right eye = -5.0 and cylinder for right eye = -3.5 hence total power for right eye = -8.5 thus require ultra thin/high index lenses). Please consult our Opticians if you have any questions regarding this.

 

Hard and Super Hard Lens Coating:

Hard coating is standard on all our lenses.  Hard coating essentially forms a protective layer on the lenses that helps guard against scratches.  Super hard coat (optional extra) is also available, which is an even tougher coating for maximum scratch protection.

 

Anti-Reflective Lens Coating:

This coating allows light to travel through the rear-side of the lenses instead of reflecting back into the eyes (i.e. stops you seeing a reflection of your own eye).  This is especially useful for indoor use as well as night time use (e.g. reduces glare from bright headlights coming from the rear).  Anti-reflective coating is different from polarized lenses (see section on polarized lenses below for more details).

 

Hydrophobic Lens Coating:

It repels water (or sweat) off the lenses much more effectively than regular lenses.  This coating also makes it much easier and quicker to wipe clean your lenses so you take less time off the ball.

 

Color Lens Tinting:

A common misconception is that only color tinted lenses provide UV protection while clear lenses do not; this is not always true. All our lenses, including clear ones, are UV400 rated that offers maximum UV protection against harmful UV radiation from the sun.  Color tinting, apart from reducing sunglare, can also help improve contrast (e.g. help you see the ball better on a green field) as well as depth perception, depending on the type of surface or surroundings you enjoy your sport in, together with the lighting conditions.

Brown: Improves depth perception and contrast, particularly against grassy green fields or blue sky.  Often used for tennis, golf, boating, soccer etc.

Grey: Grey color or smoke tinted lenses do not alter natural colors and are great for general outdoor use.

Green: Improves contrast (less so compared with brown) but doesn't affect color balance as much.  It also reduces glare while brightening shadows.  A good general purpose color for outdoor sports such as golf.

Yellow: Increases contrast under low light conditions such as fog, first light or late afternoons/early evenings and also flat light condition (i.e. indoor pool lighting).  It also delivers sharper focus since it filters blue light.  Generally used for indoor swimming, cycling, skiing, tennis, archery and shooting.

 

Polarized Lenses:

Not to be confused with anti-reflective lens coating (see above), these lenses reduce glare reflecting off shiny surfaces such as snow and water, thus, for example, allows you to see marine life/fish under the water that's normally hidden behind sunglare (great for fishing).  Essentially, ideal for outdoor use under bright sunlight.

 

Transitions/Photochromic Lenses:

These lenses combine the best of both worlds; the lenses look practically clear (only a very slight grey tint is visible) under low light conditions while turning into grey tinted lenses when exposed to sunlight (level of tint changes according to sunlight intensity). These lenses are ideal for those who are active both indoors and outdoors.  They are also great for cyclists/bikers, for example, that start their rides very early in the morning (low light) and then finish up later in the morning (brighter sunlight) since they can simply take with them one pair instead of 2 pairs of glasses.

 

Mirror Lens Coating:

While mainly selected for cosmetic reasons, they do also help reduce glare.  One thing to note when ordeing is that mirror coating will only show up on color tinted lenses (will not show up on clear lenses).
