Some cheaper anti-glare coatings can make glasses very difficult to keep clean. These budget coatings get smudged very easily, should anything touch them. Most glasses wearers know how irritating it can be, constantly cleaning grubby lenses.
We recommend a Crizal Forte anti-glare lens coat. This scotchgard coating has a number of great benefits:
- It is very tough, and doesn’t scratch easily.
- It’s smudge resistant, and will stay cleaner than other lenses.
- It is also easier to clean, when it does get dirty .
- It lets through 99% of light, (up to 30% more light than cheaper alternatives), and minimises reflections and glare.
It’s a little more expensive than standard anti glare coatings, but well worth it when you consider the extra benefits.

- Varifocals have the distance prescription at the top of the lens, so when you’re looking straight ahead, things should be clear far away.
- There is a gradual change in the prescription from top to bottom of the lens, where your reading area is located.
- Because all these powers are blended together in the lens, there are distortions at the sides of the lenses, and only a central channel in the lens has clear vision.
- People with lower quality varifocals will notice that they have to move their head from side to side a lot when reading in order to keep within the narrow central zone in the lens.
- Superior quality varifocals have less distortion than cheaper ones. This means the wearer will have a wider clear zone in the lens, and enjoy greater comfort with the glasses. You may still have to move your head a little from side to side when reading, but not nearly as much.
- Like all superior products, they cost a bit extra compared to standard varifocals, but considering the added benefits, they’re well worth it.
The cheap varifocal has a narrow area of clear vision centrally, and a narrow area for computer and reading due to distortions at the lens edges.

We all know that spotting your ball as it hooks or slices its way to oblivion is one of the most frustrating parts of your golf game. Even worse is depending on your colleagues to tell you where your ball has landed.
Why not give your self every advantage so you can have the confidence to follow that ball on its journey. To improve the contrast ratios and thus enhance your visual recognition you need the right tints and lenses.
For Golf we recommend:
• Transitions VI and Scotchgard Forte coating – hydrophobic and smudge repellent
• Essilor Master Brown 24% LTF
• Large frame for a wide field of view

Top Tips for Sports eye-wear over the next few weeks !
How you perform at sports often depends on your tools and gear. Hand-eye co-ordination is a critical success factor in most sports. So over the next few weeks we will be sharing some of our secrets for enhanced visual recognition which hopefully will be relevant to your favourite sport. I hope you enjoy the tips and put them into practice!
Firstly a little background:
Excessive Ultraviolet Light can cause you a lot of harm. Short-wave UV is present in sunlight and particularly at high altitudes, especially where the sun is reflected from the sand, snow or sea.
Tinted lenses are designed to operate at contrast filters to give you the edge when playing competitive sports. They absorb specific wavelengths of light and increase contrast, therefore providing enhanced visual recognition. You can see it faster than you opponent.
Tip No 1.
For Snow Skiing we recommend:
• Large slightly wrap spectacle frame for maximum protection
• Mirror tint to reflect UV
• Essilor Touareg Brown 12% LTF suitable for snow skiing, rock climbing,mountain biking and hiking
• Essilor Sherpa Brown 5% LTF suitable for glacier skiing and mountain climbing. Note as this level of tint is a class 4 and therefore it is not suitable for daytime driving.
