Listings of sunglasses for men in India often show UV400, polarised and 100% UV side by side, and a first time buyer cannot always tell whether these describe one feature or several. They describe different features, and a pair can carry one without the other.
The same confusion affects pairs bought as gifts for a father, a brother or a friend. A gift buyer has even less information about how the frame sits on the face, so the printed measurements matter more.
What UV400 and polarised each mean
An explainer published by IPS News says UV400 is a label for lenses that block all light up to 400 nm, a range that covers both UVA and UVB rays. The article links ultraviolet exposure with certain eye conditions but describes that link as unconfirmed.
Polarisation is a separate feature. As per the same explainer, polarised lenses reduce glare but do not block ultraviolet light on their own, and lenses that protect against UV are not necessarily polarised. The article advises buyers to look for both.
Fastrack describes the glare side in its own terms. Its brand page says polarised lenses reduce glare from water, snow and vehicle hoods.
On ultraviolet light, the Fastrack FAQ says its lenses are treated to block 100% of UVA and UVB. This is the brand’s own statement, and it was not checked by any independent laboratory for this guide.
Ray Ban India makes a different kind of claim. Its product pages say polarised lenses block more than 99% of the reflected lights, which concerns reflected light and not ultraviolet rays. The four Ray Ban pages read for this guide print no UV wording at all, so the UV label has to be looked for on each listing before a pair is chosen.
Lens darkness and road use
The Swiss Federal Office of Public Health grades sunglasses in five filter categories, from 0 to 4, according to how much light the lens passes. Its factsheet says the two lightest categories are not suitable as sunglasses, and it names the two middle ones, 2 and 3, for everyday use.
Category 3 is meant for bright places such as beaches and mountains. Category 4 is for extreme glare at sea, in deserts, on high mountains or over snowfields.
Lenses of category 4 are too dark to show traffic lights, and the factsheet bars them from road use. The Irish consumer body CCPC gives the same warning about that category and driving.
The ABDO eye care FAQ says most sunglasses suit daytime driving apart from very dark tints, and it calls an anti reflection coating a must for driving. The same FAQ says polarised lenses cut glare, and that a mirror coating on polarised lenses suits use on water and on bright days.
On tint, the Swiss factsheet adds that UV protection depends on the lens material and not on the colour or tint of the lens. Moorfields Eye Hospital warns that dark lenses without effective UV filtering make the pupils widen and let in more harmful UV, so darkness alone gives no protection.
Marks on the pair and its papers
The ISO 12312-1 standard covers sunglasses for general use, meaning plano pairs that carry no prescription power, along with clip ons. It includes pairs used on the road and for driving, and it excludes ski goggles, sport eyewear and occupational protection.
Moorfields says a UV 400 mark indicates protection from both UVA and UVB rays, and that a CE mark indicates compliance with European standards. It also says counterfeit sunglasses often give little or no protection from the sun.
The CCPC says the protection class should be marked on each pair, from 0 for no UV protection up to 4. It adds that the CE mark must be visible and legible, and that it must be marked indelibly on the glasses.
According to the CCPC, the information note should name the model, the manufacturer’s name and address, the filter type and category, and the cleaning instructions. The Ray Ban India pages print no UV label, so these marks and the note would be the place to look on a delivered pair.
Reading fit from measurements
Ray Ban India publishes lens width, bridge and temple length in mm on its product pages. One page gives a 51 mm lens with a 21 mm bridge and another gives a 58 mm lens with an 18 mm bridge, so the numbers differ between models of the same brand.
Buyers who already own a pair that sits well can compare these three numbers against that pair. The same comparison works for a gift, using a pair the recipient already wears.
Frame material is not always written out. The New Clubmaster page gives only a polished front finish and a silver temple, with no material named.
Fastrack’s FAQ names TR-90 and metal alloys as frame materials but does not say which product uses which.
Some pages also contradict themselves on size. The RB4264 page shows a lens width of 58 mm in one place and 57.8 mm in a lens table, while the Justin page lists 53.9 mm in its product details and 55 mm in its size section. Reading the full specification block, and not only the model name, is the way to find such differences.
Four Ray Ban pairs with published measurements
All four pairs below are polarised as per their Ray Ban India pages, and all four list a temple length of 145 mm. None of the pages states UV protection wording, so that check remains with the buyer.
The Lifestyle 0RB3703M in Arista with a brown mirror lens has a polycarbonate lens and a lens height of 45.8 mm, along with the width and bridge given above. The page shows a 2 year warranty and links to a standard warranty page. It names no frame material beyond the colour.
New Clubmaster 0RB4416 in silver is the only pair here with a glass lens. Its lens width equals that of the Lifestyle, the bridge is 20 mm, and the warranty and return terms are linked but not written out.
RB4264 Chromance combines a nylon frame with a polycarbonate lens. Its lens height is 46.5 mm, and the page lists a 2 year warranty.
Justin 0RB4165 with a dark blue lens also has a nylon frame and a polycarbonate lens. Its bridge is 16 mm, the narrowest of the four, and the page does not write out a return window.
Which pair suits which buyer
The Lifestyle suits a buyer who wants a mirror finish on a polarised lens, a larger lens and a brand warranty. Its page leaves out the frame material, so that detail would have to come from the seller.
A buyer who prefers the classic clubmaster outline and a glass lens is the one the New Clubmaster suits, and the UV label would still need to be confirmed separately.
The RB4264 offers a wider lens on a light nylon frame, while the Justin pairs a nylon frame with a narrower bridge and a dark blue lens. For the Justin, the two listed lens widths should be settled with the seller before ordering.
Warranty, fit and care
Ray Ban India states that its warranty covers breakage from material or workmanship defects for two years from the date of purchase. It excludes scratches on the sun lenses, damage from accident or abuse, normal wear and unauthorised repairs.
A claim needs the frame sent in a cardboard box, together with contact details, a copy of the invoice and a completed product complaint form. The buyer pays for shipping, which should be tracked, and Ray Ban is not responsible for parcels lost in transit.
For an accepted claim the remedy is repair with spare parts or a replacement. A discontinued model is replaced with a product of similar value, and the company states that its decision on a claim is final.
The Swiss factsheet says a good fit has lenses that reach up to the eyebrows and cover the width of the face. It also says scratches reduce UV protection, so worn or scratched pairs should be thrown away.
Included with the RB4264 Chromance order are a case and a cleaning cloth, and its page describes a lightweight nylon frame with polycarbonate lenses. The retailer FramesDirect advises rinsing under lukewarm water, using a small amount of lotion free soap and drying with a lint free microfibre cloth.
It warns against hot water, paper towels and household cleaners. FramesDirect adds that polarised lenses need extra care, and that glasses are best kept in their case and away from extreme heat, which can cause crazing on coated lenses.
What a listing needs to state
Listings differ in how much they print, and a short checklist shows where the gaps usually are.
- The UV wording, such as a UV400 label, separate from any polarised mention.
- Whether the lens is polarised, as a yes or no.
- Lens width, bridge and temple length in mm.
- The frame material, and not only the colour or finish.
- The warranty terms and the return window, written out on the page.
Ray Ban India links its warranty page without reproducing the terms on the product pages. The IPS News explainer directs buyers who are unsure about protection to an eye care practitioner.
