you may be asked what lens index you want to choose. The lens index
is a number that represents the refractive index of lens material.
It is used to measure how much a lens material bends light, and can
affect the thickness and weight of the lens.
When choosing your

available, as they can greatly impact the appearance, comfort, and

>, so here is a brief rundown of the different lens index options
you can choose from.
Standard (1.5)
This lens index is ideal for the majority of prescriptions,
particularly those with weaker strength. However, if your
prescription strength exceeds +3.00 or -3.00, the lenses may
start to appear bulkier.
Thin (1.6)
The 1.6 lens index is a suitable choice for prescriptions within
the range of +4.00 and -4.00. These lenses are approximately 23%
slimmer than standard plastic lenses. However, if your
prescription exceeds this range, the lenses may begin to appear
thicker.
Thinner (1.67)
The 1.67 lens index is one of the most commonly selected lens
options. It is about 15% thinner and 25% flatter compared to the
1.6 option. It is well-suited for prescriptions ranging from
+6.00 to -6.00. However, prescriptions beyond this range may
appear noticeably thicker.
Thinnest (1.74)
The thinnest plastic lens available on the market. It is around
50% thinner than the 1.5 standard plastic lens and 30% lighter
than the glass equivalent. It is ideal for medium to high
prescriptions, providing a slim and lightweight solution for
those with strong corrective needs.

So now you know the different types, what are the actual benefits of
having thinner lenses?
Benefits
Aesthetics
Thinner lenses with a higher index look a lot thinner and
lighter. This can be an attractive option for people with strong
prescriptions. Perfect if you want to avoid the 'coke bottle'
effect that can result from thick lenses.
Comfort
Thinner lenses are often more comfortable to wear. They put less
weight on the nose and ears and can reduce pressure around the
eyes.
Clarity
High-index lenses are made from materials that bend light more
efficiently. This reduces lens distortion and improves visual
clarity compared to traditional lenses.
In conclusion, if you have a strong prescription, choosing a thinner
lens index can result in a more comfortable, clearer, and stylish
pair of
