UV400, Polarized, BIS Certified: What Every Nxtedit Pair Includes

Quick Answer

Every Nxtedit pair carries UV400 lenses, which block 100% of UVA and UVB rays up to 400 nanometres. Polarization is a separate feature that cuts reflected glare from roads and water, and it is available on our dedicated polarized range rather than on every frame. BIS certification is the Indian standards mark for eyewear, and it is worth understanding before you buy anything. Prices run from ₹1,899 to ₹3,499, and every order ships with a rigid box, pouch and microfibre cloth. Here is what each term means in plain language.

Introduction

Three terms appear on almost every sunglasses listing in India: UV400, polarized, and BIS certified. Most buyers assume they mean the same thing. They do not. One protects against radiation, one improves comfort in bright light, and one is a standards mark about how the product was tested.

Knowing the difference is the fastest way to judge any brand, including ours.

UV400: the one thing you should never skip

UV400 means the lens blocks all light up to a wavelength of 400 nanometres, which covers both UVA and UVB rays completely.

This matters more in India than most people realise. UV exposure here is year-round, and damage builds up over decades. Long-term unprotected exposure is linked to cataracts, a leading cause of blindness in India.

The common mistake is assuming a dark lens is a protective lens. Tint controls brightness, not UV blocking. A ₹200 roadside pair can be darker than a certified one and still let UV straight through, and because your pupil opens wider behind a dark lens, it can be worse than wearing nothing.

Every Nxtedit pair has UV400 lenses. No exceptions, no upgrade tier, no asterisk. That is the floor we set before designing anything else.

Polarized: what it adds, and who needs it

Polarization is not UV protection. It is a filter that cuts glare bouncing off flat surfaces such as roads, water, glass and car bonnets.

You will notice it if you drive on highways, ride a two-wheeler, spend time near water at Goa or Vizag, or travel to hill stations where snow reflects hard. You will barely notice it if you wear sunglasses mainly in the city or as a style piece.

Nxtedit runs a dedicated polarized category, so you can filter for it directly. It sits alongside our standard range, because nobody should pay for a feature they will not use. Buyers comparing the best sunglasses for men often overpay here without needing to.

BIS certification explained

BIS stands for the Bureau of Indian Standards. A BIS licence means a product has been tested against a published Indian standard, and eyewear tests fall under the IS 7524 series covering optical tests for eye protectors.

Here is the honest position, which matters more than a marketing claim:

• A BIS mark tells you the product was tested to an Indian standard, not simply labelled.
• Displaying a BIS mark without a valid licence is an offence under the BIS Act, so treat unverified claims with suspicion, from any brand.
• Ask for a licence number when certification is claimed. A real licence can be checked.

Why Nxtedit gives the most luxury per rupee

We are not the cheapest, and will not claim to be. Fastrack is cheaper. We set out to find the lowest price at which a pair still feels premium in your hand and on your face.

That means UV400 as a baseline rather than a feature, lightweight frames, current designs, and packaging that feels like an occasion. In the ₹2,000 to ₹3,500 band, that combination puts us on the best sunglasses brand shortlist for anyone shopping sunglasses for men or women.

The Nxtedit collections

• Coastal Line: beach glare and salt air
• City Chrome: sharp urban frames including Plum Noir, Steel Edge and Cobalt Wire
• Desert Heat: bright, high-exposure conditions
• Aura Series: lighter, softer shapes such as Olive Halo
• Heritage: classic tortoise and retro shapes such as Tortoise Luxe and Jade Luxe

You can also shop by occasion: Everyday, Driving, Beach, Travel, Night Out and Work. Our sunglasses for men cover rectangle, round and rimless shapes, and women's styles include cat-eye frames such as Glam Noir and Amber Cat.

Premium packaging and the luxury feel

Every Nxtedit order includes a rigid sunglasses box, a soft pouch and a microfibre cleaning cloth.

This is not decoration. A hard case is the difference between lenses lasting two years and getting scratched in three weeks at the bottom of a bag. The cloth exists because wiping lenses on your shirt destroys the coating. And the box makes any pair giftable straight out of the parcel.

FAQs

Is UV400 the same as 100% UV protection?
Yes. UV400 blocks all UV rays up to 400nm, which covers UVA and UVB completely.

Do darker lenses protect better?
No. Tint controls brightness only. A dark lens with no UV400 rating offers no real protection.

Are all Nxtedit sunglasses polarized?
No. Every pair is UV400. Polarization is available on our dedicated polarized range.

Do I need polarized lenses?
If you drive, ride, or spend time near water or snow, yes. For city and style wear, UV400 alone is enough.

What is BIS certification for sunglasses?
It means the product has been tested against an Indian standard under the IS 7524 series. Always ask for a licence number when a brand claims it.

What are the best sunglasses for men who drive daily?
A polarized UV400 pair in a rectangle or wayfarer shape. Amber and brown tints improve contrast on Indian roads.

How do I care for the lenses?
Use the microfibre cloth, store the pair in its box, and keep it off the car dashboard. Heat degrades lens coatings quickly in Indian summers.

What is the return policy?
Returns within 3 days of delivery. Damaged, defective or wrong products get a full refund or free replacement. Change-of-mind returns get store credit or one exchange.
