Sarah Knows Eyes

I touched upon this briefly before, but I felt it deserved a blog all of it's very own, as it combines two of my favourite things: sunglasses and Star Trek.

The ever-fabulous Rihanna has collaborated with fashion behemoth Dior to create an exclusive range of future-fantastic sunglasses, and you'll never guess where her inspiration came from... only frickin' Star Trek!!

Chatting with Dior mag Rihanna says:

"DM: Can you tell us about your inspiration?

R: Believe it or not, La Forge from "Star Trek" back in the day! I've always been obsessed with his eyewear, and when I got to Dior and saw the materials I could play with, it all just came together."

These little beauties are available in five metallic colours and in one luscious gold-plated version (sadly sold out I believe).














Since debuting the "La Forge", Rihanna has further confirmed her status as an out-and-proud Trekkie, by joining in Star Trek's 50th anniversary celebrations AND recording an exclusive track, Sledgehammer, for the soundtrack of new movie, Star Trek Beyond! (Which can I say is AWESOME! The track, and the movie!) She's a true "TrekkieGirl" ;)

And, is it just me or is Ri-Ri absolutely rockin' that Seven-of-Nine-esque silver lamay body suit?! HAWT!!!

I was going to term July the SarahKnowsEyes “fashion month”, as following my round trend blog, I have a couple of other posts up my sleeve that tie-in quite nicely. Admittedly I had intended to post these roughly one per week, but having just started a new job (woo-hoo!) things haven’t quite gone to plan! So I’m just going to try to post them all now… July has only JUST finished after all!

A couple of months ago I was trawling the Opticians of Camden with my friend, as I’d promised we’d find her the perfect pair of glasses. Having tried on every combination of round, square, oval, rectangular frames, we discovered that the more unusual “cat eye” was the perfect shape for her! She particularly fell in love with this pair at General Eyewear:



The retro/vintage vibe has been bubbling away under the surface for the past couple of years, with many loyal fans, and some absolute beauties have been coming through the practice. The cat eye is actually very “in” at the minute. Just the other day, this beautiful pair of frames was left with us to have new lenses put in…

A patient who is well known for her eclectic choice of frames recommended this quirky little wesbite to me - Here are a just a few of my favourite picks:






O.M.G. I am in LOVE! I want them ALL!

In case you’ve been living under a rock these past few months, you may have noticed a new trend in the world of Optics – everything’s gone round!

During my 14 years in practice, every now and then you would encounter somebody looking for a “John Lennon” – the round frame is synonymous with the icon, who was rarely seen without them.


However, I wouldn’t exactly have said they were an en vogue choice? Until now. Sunglasses, Ophthalmic frames, you name it, round is in and here is the proof…

Back in December, Tatler published this article, confirming my suspicions that a new trend was about to hit:



Cue, the ‘big brands’ jumping aboard the round frame train in their glossy advertisements:



And follow suit a plethora of celebrities rockin’ the round frame:



One of the biggest drivers of this new trend has been Dior’s “So Real”, the “new Wayfarer” according to March’s Glamour magazine (they’re featured twice in the edition!):


And since Rihanna featured in their ad campaign...



…the A-listers have certainly been clamouring to be seen in its multitude of colour combinations:



You know a trend is firmly cemented when they are used in non-Optical related ad campaigns:


My favourite wearer of the round spectacle frame has to be McFly’s Tom Fletcher, who has the style in several colours and isn’t afraid to bear them all over his Instagram. ❤️ you Tom!



If you read my blog post “The Significance of Face Shape when Choosing Glasses”, you’ll know that this trend is perfect, as round spectacles tend to suit most face shapes (oval/long/square/heart), possibly with the exception of those who have a more rounded face shape, which can serve to emphasise ithe fact. However, as I always say never be afraid to try them on, because you never know, you might just look awesome in them!?


If you have succumbed to the round trend please send me a picture (preferably of you wearing them!) as I’d love to see them! Share them on my Facebook or Twitter page using the hashtag #roundframes – thank you!

Believe it or not, this post is actually one of the reasons I first started SarahKnowsEyes, so I’ve had it in mind for quite some time! In fact, it was whilst watching Edgar “Pitbull” Davids, playing for the RoW team during SoccerAid 2014 (I was only watching because Danny from McFly was playing for England!), that it occurred to me that many people might be wondering why he wears goggles when he’s playing football. It’s because he suffers from glaucoma, and whilst a person newly diagnosed with this condition may feel like it’s the end of the world, Davids is proof that it's absolutely not – he is after all an international footballing legend! And so SarahKnowsEyes was born, created as a platform for me to impart just this sort of knowledge, and because I’m fortunate enough to be in a position to do so. (I just had to wait until now for this particular post, as SoccerAid is a biennial event! And fortunately Edgar Davids is playing again!)

So what exactly is glaucoma? The eyeball contains a fluid called aqueous humor which is constantly produced by the eye, with any excess drained though tiny little tubes. If for some reason, this fluid cannot drain properly, pressure builds up within the eye, this is known as the 'intraocular pressure'. Glaucoma is actually a group of eye diseases in which the optic nerve (which connects your eye to your brain) and the nerve fibres from the retina (the light-sensitive nerve tissue that lines the back of the eye) are damaged by this intraocular pressure. This may be because the pressure is higher than normal, or because the nerve is more susceptible to damage from pressure. Glaucoma often affects both eyes, usually to varying degrees and one eye may develop glaucoma quicker than the other.


There are four main types of glaucoma: -

  • Chronic open-angle glaucoma – this is the most common type and develops very slowly.
  • Primary angle-closure glaucoma – this is rare and can occur slowly (chronic) or may develop rapidly (acute) with a sudden, painful build-up of pressure in the eye.
  • Secondary glaucoma – this mainly occurs as a result of an eye injury or another eye condition, such as uveitis (inflammation of the middle layer of the eye).
  • Developmental glaucoma (congenital glaucoma) – a rare but sometimes serious type of glaucoma which occurs in very young children, caused by an abnormality of the eye.

Anyone can develop glaucoma, however, there are people at a greater risk, such as if you are: -

  • Aged over 40.
  • Very short-sighted.
  • Of African or Caribbean origin (or with very dark coloured eyes).
  • Closely related to someone with glaucoma, as it can be hereditary. (In fact, if one of your parents or children, or a brother or sister, has glaucoma, and you are over 40, the NHS will pay for your eye examination.)

Some people naturally have pressure that is above normal range, but this pressure does not cause any damage to their eyes. Although they do not have glaucoma, they may still be more likely to develop it.

Because you often cannot feel the pressure in your eyes, and damage occurs slowly, you may not even know you have glaucoma until a great deal of damage has already been done. If you have glaucoma but do not treat it, your eyesight will gradually get worse….

This damage is irreparable, and you could eventually go blind! Remembering however that this is supposed to be an "upbeat" blog post – the good news, is that treatment as simple as eye drops, may stop it getting worse! This is why early detection is absolutely vital. Optometrists recommend that most people should get their eyes tested every two years, however if you are at risk of developing glaucoma, they may recommend more frequent NHS eye examinations.

For more information about how glaucoma is detected, click here.

What will happen if you do get diagnosed with glaucoma? Unfortunately, there is currently no cure for glaucoma, and although any existing damage will most likely be permanent, its progression can effectively be halted. If your Optometrist suspects that you may have glaucoma, he or she will refer you to an Ophthalmologist. If you do have glaucoma, you will be given eye drops to use every day, these will reduce the pressure within the eye(s) and help control the build-up of fluid. Don’t worry, they won’t hurt!

(Love this picture so much, I just had to use it again!)

Because you won’t feel different in any way, you won’t know if the treatment is working, but your sight could get much worse if you stop the treatment, therefore it is very important that you, a) attend your follow-up appointments, and b) keep using the drops, even if you can’t tell if they’re helping. If you find it hard to use eye drops, there are special bottles available or holders to make it easier. In a small number of cases, an Ophthalmologist may recommend that you have an operation, called a trabectome, to help drain the fluid.

So why does Edgar Davids wear goggles when he’s playing football? To prevent his eyes from a traumatic injury that could further raise his intraocular pressure. The point being that it doesn’t stop him doing what he loves and making a very successful and lucrative career from it! Ever wondered why U2 frontman Bono always wears sunglasses?

..because he too has glaucoma! Now, I have to admit that I had to research this one – apparently, loss of contrast sensitivity, problems with glare, and light sensitivity are some of the possible effects of glaucoma that may interfere with your day-to-day activities, with some glaucoma medications exacerbating the problem even further. Sunglasses are an easy solution that can make life more comfortable, while also providing critical protection from the sun’s damaging ultraviolet (UV) rays when outdoors. See? Glaucoma hasn’t prevented Bono from being a world famous rockstar either?!

In fact, Bono is so rarely seen without his trademark sunglasses, that he was the perfect “celebrity ambassador” to front Revo’s brand campaign: “Buy Vision, Give Sight”. The legendary rockstar has created his own line of luxury sunglasses for the brand – for which he also features in their advertising campaign – $10 from the sale of every pair will go towards helping those fighting for their sight around the world. The creative collaboration hopes to raise $10million to improve access to eye screening, prescription glasses and eye health care in under-resourced communities, in a bid to combat vision impairment and unnecessary blindness.

In a statement on Revo’s official website, Bono said:

“The ‘Buy Vision, Give Sight’ campaign is a very personal one for me. Thanks to good medical care my eyes are okay, but tens of millions of people around the world with sight problems don’t have access to glasses, or even a basic eye test. Poor eyesight may not be life-threatening, but it dramatically affects your life and your livelihood if you aren’t able to fix it.

Sight is a human right and the ‘Buy Vision, Give Sight’ initiative will help ensure millions of people have access to the eye exams and glasses they need to see.”

What a great guy huh?

Actress Whoopi Goldberg also suffers from the condition….

Well, hopefully this has proved that being diagnosed with glaucoma really isn’t the end of the world and if it’s diagnosed early and treated effectively, you should be able to lead a perfectly “normal” life, and do whatever you want to do (within reason – bungee jumping is probably ill advised?!). However, as demonstrated in this and countless blog posts before it – early detection is the key and subsequently regular eye examinations are a must! So, if you haven’t had your eyes tested for two years or more, do so, pronto, especially if you have a parent, child, brother or sister with glaucoma! You’re not doing yourself any favours by procrastinating! Here endeth the lecture.
