It’s A Wrap – Prescription Sunglasses

Sunday, September 5th, 2010

For us spec wearers, summer gives us the opportunity to blend in with every other cool dude, disguising our myopia with prescription sunglasses. This can be blessing or a curse, as we try to get the red-carpet film star or beach babe look in our sunnies while making sure we can see and look good! Prescription sunglasses have become an economical option for all in recent years, thanks to special offer prices and more and more styles becoming available. The only thing you need to take care with is frames that are unsuitable for prescription lenses.

The sunglass trend is always slightly funkier than for clear ophthalmic lenses, going bigger, bolder, and sometimes, more curved. This wrap around style is excellent for sunglasses, as it stops light getting in, and if you’re a keen cyclist then it stops the wind whistling around your eyes too. For non-prescription lenses a large wrap around shield type sunnie can therefore be ideal.

When it comes to adding lens power to a wrap frame however, you can run into problems. Prescription lenses have a curve which is governed by your lens strength. The wonderful laws of Physics do allow us to play around with this to some extent, so you can have curved lenses made to your prescription if the strength is low and the curve can coincide with that of your super cool sunnies. The key here is to talk to the optician before raising your expectations and falling in love with a curvaceous but unobtainable ideal – story of my life!! Make sure the frame you choose has traditional mounts, not some kind of fancy rimless which cannot be glazed with new lenses. Keep the size down as much as possible, and post to us or take into your optician to be assessed. We can get specially made wrap lenses if necessary but these are more expensive, full quotes are always given.

When the Postie delivers your new sunnies into your excited hands, note that your vision might feel a little odd to start with. This is due to the wrap altering your peripheral vision slightly. It usually settles down quite quickly and you’ll stop noticing it. Try wandering around the garden in them before diving behind the wheel or handle bars. Then await the sunshine and get posing!

Form & Function

Friday, July 2nd, 2010

We’ve often said that it can be a pleasure to buy specs if you treat yourself to a lovely trendy frame and possibly splash out on a Designer name to give you confidence in yourself and the good quality of the product. Glasses must look good to make you feel happy wearing them in your everyday lives. You do however have to take heed of advice from opticians and optical assistants when you make your choice, because the frame does more than just look good on your face – it has to be the perfect blend of form and function to suit your prescription and your lifestyle needs.

It’s all very well to fall in love with a frame and be happy with the colour, shape and size, and for many patients with simple prescriptions the decision is easily made just because you like the looks of the frame. But it can get complicated if you choose a very curved or a very big frame, because the annoying rules of Physics prevent us from making up any old lens power in any size or curve!

Specs for sport or sun wear sometimes lead a client to choose a very wrap-around or very large size frame, and ask us to glaze it with their prescription lenses. This is a situation where form and function requires careful thought. The dispensing optician who helps you to make your mind up on the frame and lens combination needs to consider your prescription, the size of your face, the detailed measurements of the frame and the amount of curve. So if you can’t always have your first choice of frame there is a good reason for it! We always do our best to work with the patient to give them what they want, but sometimes the frame will simply not suit a prescription lens. Lens power gives the lens a specific curve, and this may not fit within the frame. Or the wrap of the frame may give rise to distortion at the edges, which is uncomfortable and possibly even dangerous if you’re driving or cycling in them and need to be perfectly aware of upcoming vehicles in your peripheral vision. We may need to order specialised curved lenses or source an alternative frame for you. Consideration of your requirements and careful selection will give you a form of lens that fulfils your required function perfectly.

The Perfect Fit

Wednesday, June 9th, 2010

People are often confused when it comes to choosing spex, bewildered by the vast choice of frames, lenses, and coatings on offer. When we choose clothes or shoes we’ve often seen something we like in a magazine or an a friend, but with specs the subtleties of colour and design are often not that noticeable, until that is you come to choose yours, and such tiny details can make it hard for you to come to a decision. To help in your choice, let’s take a look at the most important factors in choosing a frame that will look perfect on you and do its job.

One of the biggest issues is in how the frame looks on your face, where it should sit and how the frame should fit you. There are three aspects to this question – the current trend for frame size, your proportions, and the lens power that you need. In the Seventies, all frames were huge, and it was very difficult to find anything that wasn’t big. Today the situation is less cut and dried, and there are frames in every size available.

For a frame to look in proportion to you, your eyes should sit in the centre of the lens. If the frame is too narrow your eyes will be at the outside edges of the lens, too wide and there’ll be lots of spare lens either side of your eyes! This adds thickness to your prescription lenses, increases edge distortion, and will make you look a bit shifty as your eyes will appear very close together! The frame should not sit on your cheeks, it will drive you mad as it moves up and down when you eat or laugh. The top edge should sit below your eye brows, and follow the shape of the brows – for example curved brows need a curved top frame.

If you are very short sighted it will benefit you to choose a small frame, as the lenses will then be thinner. So within the boundaries of fashion and looks, go as small as you can. Long sighted patients benefit from smaller frames too; we can have the lens manufactured from scratch to suit your frame, which again reduces thickness.

The frame sides must not dig into the side of your temples. This will give you a headache and strain the frame! There should be a gap between your head and the frame until the sides curve behind the ears, where they should sit closely to your head. The nose pads are only a resting area for the frame; don’t pinch them in until you can’t breathe!

Finding a frame that suits your face and your proportions will help you to feel happy wearing your glasses, as they become a part of you. Ask a friend, try before you buy – there’s a frame for every face, you just have to find your perfect fit!

Keep Your Eye on The Ball Golfers!

Saturday, May 16th, 2009

We all know that the Golfer’s amongst us will do anything to up their game – from buying every new club that manufacturers can produce to wearing some very dodgy trousers. If you really want to get serious though, let’s see if some eye wear technology can give you that little extra edge – move over Tiger Woods!

There are two aspects of eye wear for Golfers to consider – tinted lenses and the correct power to help you actually see. Talking about tints, golfers have two requirements – adequate sun protection and good contrast to let them see the contours of the green. If you’re out regularly make sure you have a UV filter on your specs, whether tinted or not. Even on overcast days you can be at risk from UV.

Tinted lenses need  a high quality, good contrast tint if dark.  An orange toned brown lets you clearly see any slight dips or rises in the greens. On duller days, some might benefit from a yellow toned tint, again to improve contrast.  Ask your optician or  email your online optician for advice.

With prescription lenses, some golfers struggle with varifocals.  The stance to tee off – chin up but looking down -  doesn’t tally with how varifocals work. You might need a single vision distance pair, which will also let you see the flag. The downside of this is that you won’t be able to see your scorecard – do you trust your team mates to do it for you?!  The other option is a varifocal with a low set reading area, again your optician or online optician will be able to sort this out for you.

Do You Have Time To Reflect?!

Sunday, May 3rd, 2009

If we told you that you could have more comfortable sight at the computer, be safer driving at night, and even look better, wouldn’t you jump at the chance?! Today’s technology can achieve all of this with one addition to your prescription lenses. This wonder product is an anti-reflection coating, and if you’re a clued up spectacle shopper you’ll have heard it mentioned, so lets take a look at it in more detail.

Wearing specs creates all of the problems above. Your shiny new spec lenses reflect light like a mirror, making you see ghost images. Reflections from the front and back surface of the spec lens also interfere with clear sight. This can be tiring as well as distracting, and in the case of night driving possibly dangerous as it makes it difficult to see headlights clearly.

Anti-reflection coatings are not visible like a tint, although you can see them if you tilt the glasses under a strong light. Then you can see an effect a bit like oil on water. The coating is a complex process, so now for the science bit! Think of light travelling as a wave, and if you can make the light waves travel out of phase with each other they will cancel each other out. Layers of coatings are used to cancel out different wavelengths of light.

The result for you is dramatically reduced reflection and therefore sharper, clearer vision. If you have a strong glasses prescription then your lenses won’t have that bottle bottom effect that we all want to avoid. The other advantage – as your glasses will look totally clear, when your other half is gazing into your eyes, they’ll see you, and not just themselves reflected back!

Are You Up to Scratch ?!

Saturday, May 2nd, 2009

I’m really enjoying buying my glasses online, because up until the net optician appeared on the scene I had a very expensive hobby – buying new prescription lenses because I kept scratching the ******* things!!! I just hope that some of you out there have done it and it’s not just me…….

When I was little my specs were changed every six months, so they were the type of NHS specials that Jarvis Cocker would kill for. I was before my time with the Jack Duckworth look due to the permanent lumps of very sticky plaster holding the arms on. Lenses were not anti-scratch then, and it showed! I gouged them on twigs in the garden, by using them to dig my favourite car out of the sandpit, (oops!) on the pavement when I fell over in them, and on the zip of my Mum’s cardie.

I put them in my cricket bag with a matchbox, my school bag with a metal ruler, and then the spare pair got wrecked after our holiday in the box with the shells I’d collected. I also discovered that if you try and remove the scratches with your Mum’s nail file it really doesn’t help…..

Nowadays I have a scratch resistant layer on my glasses. Please note the word resistant – it doesn’t help if you put your car keys in your pocket with them, or your dog runs off with them and his little puppy teeth find them soothing to chew. It helps with everyday wear and tear though, and now I’m shopping at the online optician I don’t have the expense or the embarrassment!

Being Long-Sighted

Wednesday, April 22nd, 2009

Of all the afflictions that can befall us, you’d think that long-sightedness is a fairly minor thing. I’m not blind as a bat, I can see with my specs on, I should be counting my blessings. For me though, my eye defect has been a real blight on my life……

When I was little I was quite severely bullied, because my confidence was poor due to wearing glasses. They were thick, heavy, and worst of all they magnified my eyes. Looking back at photos, I was engulfed by these big specs with my huge eyes behind them.

I wore contact lenses as soon as I could, but when I was pregnant and breast feeding my hormones affected my eyes and I couldn’t wear lenses. The happy time with my new baby was almost spoilt by the thought of wearing specs again. I was so traumatised that I couldn’t cope with the thought of choosing glasses at the Opticians.

I trawled through loads of online optician sites while breast feeding at night, steeling myself to get some glasses. I found a site I could e-mail and phone, and they were really helpful about my prescription lenses. I got lenses called aspherics which are light and flat and don’t magnify my eyes. For the first time in twenty years I have specs which I actually like wearing. If my baby has to wear glasses it’s great to know she won’t ever have to deal with the trauma that mine used to cause me.

Make Time for Make Up!

Monday, April 13th, 2009

Are you hiding behind your glasses? Are you using them to enhance your eyes, or disguise them? Maybe a few make up tips will help you to make the most of your eyes, and your eye wear.

Firstly make sure your brows are perfectly groomed, for in framing your features they frame your glasses too. Pluck stray hairs from beneath the brow line, taking care not to over pluck. Professional waxing or threading at a salon may help if you are not confident in doing this yourself. If your brows are too fair or sparse, then fill in carefully with an eyebrow pencil in soft, short strokes.

If you are short sighted, then your prescription lenses will make your eyes look smaller. Mascara will lengthen your lashes and enhance your eyes, and for evenings you could apply false lashes to make your eyes really stand out. An old make up artists trick is to use white eyeliner on the inner lash line to make eyes look bigger.

If you are long sighted then your glasses will make your eyes look bigger – fantastic! If however this makes you feel self conscious, play up your lip colour to draw attention away from the eyes, and use a dark eyeliner to minimise eye size. Always ensure that lip colour compliments your glasses frames – if you have several different pairs of prescription glasses play around with lip colours to see what suits each the best.

It’s Spring! Fashion for the New Season

Sunday, March 29th, 2009

If you’re visiting an online optician you’re obviously a smart shopper – price and fashion savvy. So let’s check out some key fashion trends for Spring and make sure they tie into your eyewear…..

With Mad Men influencing our look and our viewing habits this season, the secretarial fifties fashion vibe is back. Ultra feminine, classy and a little bit strict – something for everyone! If you adore pencil skirts and the re-emerging court shoe, then keep the theme with cats eye shaped, upswept eyeglass frames. Bold colours, little details at the outer corner of your lashes, flirtatious and very sexy!

The jumpsuit is back, for all you Mad March Hares leaping into spring. That fun Seventies disco look ties into the trend for Neon fashion – see below. If you hanker for those Roller Disco days then look for glasses frames in bold shapes and colours, with graduated tinted prescription lenses.

The first few watery rays of Spring sunshine always encourages us to bring some colour into our lives. The new palette includes yellow, orange, and of course the neons – you could go for a colour pop in vibrant spectacle frames, brightening and updating any outfit. Be daring with your glasses and of course if you invest in a few pairs you’ve got an eye wear wardrobe to match!

Suits You Sir!

Thursday, March 26th, 2009

As a self confessed techno geek, I didn’t think glasses would be as interesting to me as the newest mobile phone or mp3 player. When I found out I needed help to read of course I had to do as much researching on line as I could, checking out all the options. I was really pleased to find some techno information to get me interested!

I found out that eyeglass frames are not just a couple of bits of wire that hold the prescription lenses in. (I admit it – I did think that to start with! My wife rolled her eyes at that because she is more interested in the shopping opportunity and loves fashion specs!)

The materials they make spectacle frames out of are state of the art. The core metal is built up with layers of different materials and then have many more coatings of colours and lacquers, including protection against your skin and pollutants. Sometimes they use Stainless Steel or Titanium which is durable, lightweight, and strong.

Hinges often incorporate springs, which help eyeglass frames to keep their shape and stop the joints from wearing. Some specs have a nylon thread instead of a whole rim, which reduces the weight further. The spectacle lens has a groove cut into it which the thread bites into. I eventually chose a pair of these specs, in a cool geeky style of course!!
