Below is a brief introduction the some of the lens options:


Thinner lenses :
High index (thinner) materials can reduce the thickness and weight of lenses by over 50%.



Scratch-Resistant coatings :
Lenses treated with these coating have a much harder surface that is more resistant to scratches.



Anti-Reflective (AR) Coatings :
These coatings virtually eliminate distracting reflections off the lens surfaces. Reducing reflected light is particularly helpful Reducing reflected light is particularly helpful for computer users and for night driving. Anti-reflection coatings also improve the cosmetic appearance of your glasses and can make thick lenses look thinner. Some AR coatings are better than others. The latest and best coatings are Multi-Layered incorporating a combination of treatments such as Anti-smudge, hydrophobic(water repellent),UV Protection and Anti-scratch treatments. Many of these come with a 2 year warrantee.



Varifocals :
Varifocal lenses, also known as progressive lenses, are used for correcting *presbyopia but unlike bifocal lenses have no visible dividing lines between the different corrections. Instead they have a graduated section in which the power of the lens progresses smoothly from one prescription to the other, allowing the wearer to see clearly at all distances. These lenses also have the benefit of looking better - they don't draw attention to the ageing process.

*Presbyopia is the loss of focusing ability that occurs naturally with age. In younger people, the lens is very flexible and the eye has a wide range of focus from far distance to close up. As you get older, the lens slowly loses its flexibility leading to a gradual decline in ability to focus on near objects. Presbyopia is not a disease but a normal and expected change which sooner or later affects everyone, whether you already wear glasses or contact lenses or not. Around the age of 40-45, you will begin to notice that you are holding the newspaper further away or need more light to read small print. There is no advantage in delaying using reading glasses, or changing to bifocals or varifocals. They will not make the eyes lazy.
