High-index lenses are another one of the options
you can choose to add on to your new frames under the Prescription checkbox on
danielwalters.com. These lenses are thinner and lighter than standard plastic
or glass lenses are, so they are perfect for those who want more
attractive-looking and comfortable eyewear.
These lenses are highly recommended for
anyone who has a very strong prescription – whether it is for near or distance
vision or astigmatism – as well as anyone who may want slimmer lenses.
Now you may be wondering:
why are they recommended for those with strong prescriptions?
Eyeglass lenses are used to help correct any
refractive issues that can result from your eye shape and so on by bending
light as it goes through the eyeglass lens. How much the light needs to be bent
– also known as lens power – in order for you to have good vision is written on
The refractive errors as well as the lens
power you need to correct them are measured in diopters, written just as D. For
example, if you are just mildly nearsighted, your prescription could say -2.50
D. If you are severely nearsighted, you might need -8.00 D. A plus sign
High-index lenses help out with comfort by
decreasing the weight of the lens – as they can become quite heavy with higher
prescriptions – and they do this by bending light more efficiently.
This means that, even if you have a high lens
power, you will still have a thin lens.
Combine the high-index lenses with the
coatings that come free with your prescription on our website, and you will
continue to have very attractive looking eyewear that won’t scratch easily and
will look almost invisible due to the anti-glare coating.
