Need to Know

Friday, June 18th, 2010

When we first tell people that they need to wear a visual correction – glasses or contact lenses – their first reaction, and their first question, is about when they need to wear their glasses. There are a few myths surrounding this issue, so here are the facts.

Wearing glasses, or not wearing your glasses, won’t alter your sight in the long term. There are some studies to suggest that’s children’s sight can be improved with specialist lens types, but at present there’s no evidence to suggest that your correction will actually make your sight better or worse. If you don’t wear them, in the short term you’ll suffer from eye strain as you try to focus. Squinting to thread a needle or read a book will be at best uncomfortable, at worst will leave you with a nasty headache. So don’t be afraid to wear your glasses! Listen to your Optician’s advice and wear them when you need them, especially if you’re illegal to drive without them!

If you’re under the age of forty, your eyes will do the work for you in focussing close too and far away. You only need one prescription for both. For most prescriptions you’ll be perfectly fine wearing your spex all the time. If you’re short sighted, as you get near to age forty, you’ll be more comfortable taking your specs off for close work. In this case not wearing your glasses will save eye strain. If you’re long sighted you’ll start to find that you need extra magnification for close work at this point.

After age forty-ish, you need help to focus close-up, regardless of what your sight was like before this point. So if you had no prescription before this, you’ll find yourself putting specs on and off when you need to read and then look up. You could have a varifocal with no power at the top of the lens, just your close and middle distance magnification. It’s fine to wear the varifocals all through the working day if it suits your lifestyle not to have to keep taking reading specs on and off.

Trust your optician and your own common sense when it comes to the best times to wear your glasses, and the important thing is don’t suffer in trying to cope without them.

The Perfect Marriage

Monday, May 10th, 2010

When it comes to making glasses, it’s not quite as straightforward as clipping a lens into a frame and sending the wearer your blessings! For the specs to give perfect vision, look good and feel comfortable, you need the perfect marriage of suitable frame, lens design and material and coatings.

Every optical establishment needs a qualified Optometrist and a Dispensing Optician in residence. The first step is for the Optometrist to look at your prescription and make sure it makes sense with reference to your age, optical history, and visual needs. Here at the InternetGlassesCompany we have a fully professional team who verify prescriptions and check with clients if anything looks amiss. Does the power ring true for your age? If there is a difference between your two eyes does it seem likely? While every prescription is different we do get some orders that would be a miracle of science!!

The next step is for the Dispenser to look at the choice of lens material and frame. For instance – a high plus prescription may be problematic in a rimless frame as the lens edges will be thin and may chip over time. A high minus strength will be very thick in a huge frame. They also look at your pupil distance, because if you’re petite and your eyes are close together, the lenses will be thick in a big frame. If they don’t think your choices would work they contact you to suggest alternatives.

They then consider your lens choice in relation to your prescription. Are Varifocals really suitable? Will a specific lens type be very heavy? Do you really need thin materials? Again, we occasionally have to verify with the client before we go ahead. It’s not in your interest or ours to produce a finished article that just won’t work.

When the order reaches the Lab, they again will look through everything and check that the glasses will do the job. Sometimes the Dispensing Optician will have sought their advice on technical aspects of lens finishing etc before they pass the job on.

When the glasses have been completed, success is once again assessed. If we didn’t foresee a potential problem then we start all over again!  Our precious work is shipped off to you with our congratulations on your choices, and we wish you happy ever after with them!

Make it Work for Work

Friday, April 30th, 2010

Confusion arises time and time again due to the choices you have to make when you need help for reading. It’s a problem that comes to us all, as the eye ages the lens inside stops allowing you focus close too. Basically your arms get too short! As arm extensions are beyond our capabilities at present, here is the simple guide to what you need to bring life back into focus!

If you don’t have a distance prescription and you just like to sit and read:

You need simple single vision lenses. Choose a narrow frame so you can peer over the top, (on the off chance that something more interesting than the election comes onto the telly!) and have anti-scratch lenses because you’ll be taking them on and off.

If you don’t have a distance prescription, use a computer and need to read small print too:

You need Vocational lenses. These combine screen distance and near vision in one lens, allowing you to look up at the screen and check work close too. Also great for ironing and eating your dinner!!

If you have a distance prescription, and use a computer: You’ll be better off with a varifocal, which lets you see

a) Far Distance – driving, TV and generally walking around.

b) Middle Distance – Computer screen, display on a wall, across a desk.

c) Close Work – Reading, threading a needle.

These are the ultimate specs that do what your eyes used to do, allowing you to focus both far and near, without swapping specs around.

If you have a distance and a reading prescription, but don’t use a computer: You can have traditional bifocals, which are simple and correct both of your prescriptions in one lens. You wouldn’t be able to use them at the computer and some wearers find it difficult to see the dashboard clearly.

So there you go, there is a lens to suit any lifestyle, and you just need to take a few minutes to think about what would be good for you. Mail or phone us if you need advice – Vision Perfect at TheInternetGlassesCompany !

Super Size Me!

Tuesday, April 13th, 2010

Not only have It bags and shoulder pads got bigger over the past year, but sunglasses and specs have too. The minimalist, tiny frames of the past few years are fading into the background, as frames get bigger and bolder. We’ve had a few mails about this, so we thought we’d put some of those fears to rest…..

I had big frames a few years ago and they were really heavy! I love the new look but I don’t want dents on my nose again!

Frames back in the Seventies and Eighties were super huge, and the weight was often an issue. Thankfully, things have moved on in the past few years, and there are several improvements that will help you to stay in fashion and out of pain! Firstly, frame materials are now lighter and stronger, so you get durability without bulk. Nose pads made of silicone provide comfort and better support without gouging holes in your skin. Lenses also come in a greater range of high density materials, so you can save the weight with lighter lenses too.

I love big glasses but my face is really tiny. Can I stay trendy and pick something that suits me?

As with any aspect of fashion, it’s important to find the middle road of something that fits you and your lifestyle, while staying up to date. Fashion is presently more flexible than it was twenty years ago – there are large and small frames, so go for something a size up from your present specs, but not enormous. Frames that are too big will make your eyes look closer together – not a flattering look! With dark lenses in sunnies you can afford to go as big as you like, as your eyes won’t be visible through the lenses. This may be a good compromise to make you feel funky and comfortable too!

I’m quite short sighted, and my optician said I need to pick small frames, but I don’t want to look frumpy!

Your optician is quite right in that bigger frames mean thicker lenses. You can however make some wise choices that should help. Firstly, a plastic frame adds size, and the thicker rims camouflage thicker lenses. So choose something plastic, preferably with a chunky temple area. Secondly, a thinner material lens will cut down the lens thickness and the weight. Thirdly, find a frame with a fairly even shape, don’t pick and Aviator with an exaggerated drooped lens. A square or round frame will give you a more even lens edge.

I love rimless, but they don’t seem to be made very big. Can I still have them?

The problem with rimless is that the lack of rim means the lens edges are vulnerable, and the bigger the lenses the more weight you need to support. So if you have to go for rimless, always pick thinner lenses, and do listen to your optician’s advice – only go as big as they suggest. Any rimless can be scaled up to the size you require, you just need to be sensible!

Mind The Gap

Sunday, May 17th, 2009

Customers often ask us about the weird moment when you look up from close work to distance, and your sight takes a moment to catch up. It happens to specs wearers and those with no spectacle prescription. As it’s come up quite a bit we thought we’d go through this for you.

Lenses are not just the bits of plastic or glass set in spectacle frames. We all have a lens inside each eye – it’s called the crystalline lens, and along with other structures in your eyes in helps you to focus. The lens is a clever little thing that changes shape to let you focus both close too and far away. It does all this work without us even having to think about it, although as we get older – forty onwards – it loses this ability and we need reading glasses.

At any age though, the lens is still doing it’s best to help you see close up. This is why you get that little visual gap – as you focus on different distances your lens and your brain have to catch up and let you re-focus. Of course you notice it more if you’re tired, or have been concentrating hard on anything at a specific distance. It’s nothing to worry about, although you should always make sure that your prescription glasses are up to date, to give your eyes all the help they need.

When you’re working close too, give your eyes a frequent rest by looking around the room at different distances, and remembering to blink, as this washes a fresh layer of tears across the eyes to lubricate them. If you only wear reading glasses you could consider swapping to varifocals, as they let you look comfortably into the distance without having to take your specs off.

Time for Some Good News!

Saturday, May 9th, 2009

Now we all know that fifty is the new forty, but try telling that to your eyeballs! The Botox can keep those wrinkles at bay, a dash of (because you’re worth it!) dye can disguise those pesky greys, but before you know it you’re perching a pair of bifocals on your nose and wishing your arms were a bit longer! You’re not alone though, so read on for the good news…….

As your knees get a bit stiffer, so does the lens inside your eye. It looses the ability to change shape and focus close too. So you end up squinting at menus in dimly lit restaurants, giving up on threading needles, and claiming that the print in phone books is getting smaller. Nightmare! You’re turning into your Mother!

The good news I promised you:
You needn’t worry about your wrinkles anymore because you won’t be able to see them.
You don’t need to waste time plucking your eyebrows because you can’t see those either!
You have a perfect excuse never to sew a button on ever again.
If the news is too depressing – Swine flu, Gordon Brown, the Credit Crunch, expensive identity cards etc – no problem, newsprint is too small to read.

There’s also the shopping opportunity. Feel free to spend madly on delicious Diors, or gorgeous Guccis, with prescription reading lenses or varifocals. Not an exercise in vanity, more a medical appliance with a fashion twist. You’ll be able to catch up on the news when it gets better, and at least you’ll be able to read the Government leaflet on how not to spread viruses.

You might need several pairs, to keep by the phone, the computer etc. Log onto the online optician and do it the cheap and painless way. More painless than Botox anyway!
