Lenskart under it’s premium eyeglass lens brand, British Optics, offers three following lenses :

Don’t get confused with “British Opticals“, which is a UK company and I don’t think they have operations in India.

British Optics have their own website: britishoptics.com which was registered  recently on 20-07-2015 with nameserver as “ns1.domainsearchindia.com”.  And they sell their lenses exclusively on Lenskart.com. For some reason, their website is hiding it’s Contact Information in the WHOIS records, such a suspicious brand.

Hence, I can safely conclude that it’s brand owned by Lenskart. The brand is not British and has nothing to do with Britain. It’s an old marketing trick to deceive Indian consumers with foreign sounding names. Similar marketing trick is being used by some other Indian brands like Peter England, Allen Solly, Louis Phillippe, American Swan, Franco Leone and Lakme.

To compare the two most expensive lenses (Super Thin & Blue Cut) from Lenskart, I ordered two similar eyeglasses on May, 2017 with these two lenses. I decided to go with the following rimless frames for both the eyeglasses:

  • Vincent Chase SIZE ZERO VC 0315-10A1 Eyeglasses
  • Vincent Chase SIZE ZERO VC 0353-C31 Eyeglasses

Reason being, I’m used to wearing rimless frames because they’re light weight and this time, my goal was to compare both the lenses in terms of thickness as well, which wouldn’t be possible with Full Rim frames. Please note that the Blue Cut lenses have an index of 1.61 and the Super Thin lenses have an index of 1.67. My eye power is R-4.25 and L-3.5.

After receiving the package, and observing the lenses of both eyeglasses, I found no difference in width of lenses in both the eyeglasses other than the blue tint on the Blue Cut lenses. And it’s not possible to identify if the lenses I received are even from British Optics. You cannot differentiate a British Optics lens with their cheaper Klar lenses, so it’s easy to get scammed here.

Please find the pictures of both the glasses below and decide yourself if it’s worth paying the extra premium for Super Thin lenses.

Thickness Measured Using Vernier Caliper
Thickness Measured Using Vernier Caliper

I measured the middle thickness of both the lenses using a Vernier Caliper, and I found almost negligible difference in the measured thickness. I measured the thickness 3-4 times, below is the average of those readings:

  • Blue Cut Lens: R 2.2mm, L 2.10mm
  • Super Thin Lens:  R 2.13mm, L 2.03mm

I also tested the Blue Cut lenses from Lenskart using the following coloured  images. These images were made to test blue cut lenses only. But they didn’t pass both the image tests.

If you have normal color perception and your monitor can display RGB, the two images shown above should appear different. The image on the left represents a regular RGB color model. The image on the right was modified to reduce the blue hues using a photo editing software. Now try looking at the image with your blue light filtering eyewear. If you have true blue light filtering eyewear, both images will appear almost identical with the glasses.  source: blueblockglasses.com
Blue Spectrum
If you have normal colour perception and your monitor can display RGB, the two colour spectra shown above should appear different. The upper spectrum represents a normal colour range. For the lower spectrum, a photo editing software was used to remove the blue hues. As you can see, the cyan component of the spectrum (which is a mix between blue and green) appears green. The blue component has disappeared. True blue blocking glasses, or lens that filter out >90% blue light, the two spectra should appear very similar. This should occur because the glasses should do mechanically what we’ve done using the photo editing software : i.e. filter out blue light. source: blueblockglasses.com

I visited a nearby Lenskart Store to check the authenticity of Blue Cut lenses, they did a demo by passing a special blue laser light through the lenses, and I observed that only 20% of the blue light was passing.
