What is lens index and why must you know about it?
Gone are the days when the conventional rectangles and rounds in black made the perfect prescription glasses for your regulars. Today, the plethora of options in shapes, textures and colours can be styled for different occasions making you want more than just one pair.
But choosing the right pair of glasses online doesn’t end here, there are types of coatings, lens type and the lens index that you need to pick that flatters your vision and lifestyle effortlessly.
What is Lens Index?
Lens index stands for the thickness of your lenses, basically the curve of the lens diameter. The higher the index, the lesser the thickness of the lenses and the lower the index, the thicker your lenses will be.
High index lenses use optical aspheric technology into lens design giving them a flatter curve making it look like you hold a lower lens profile.
Why it Matters?
If you hold a higher prescription then you require higher index lenses, a lower prescription can use a lower basic lens index. At Optically, every pair of eyeglasses and prescription sunglasses online comes with 1.56 index lenses and an anti glare coating for no additional cost.
Once you decide your prescription needs, like the type of lenses- bifocals, multifocals or computer use, you can proceed to choose the lens index.
