The Choice is Yours!

Saturday, March 5th, 2011

You may be browsing specs online or facing the dread of the Opticians dispensing shop, but for many clients the selection of the perfect frame is a bamboozling experience that leaves many with a headache and the dread that they’ve picked the wrong thing. If you’re about to embark on this – X factor speak!! – journey, then the first basic choice boils down to 3 looks; plastic, metal, or rimless. Here are a few points to consider.

Plastic Frames – A chunky, bold, often high fashion look, with more obvious colour than a metal frame..

Perfect for – anyone allergic to metal materials

higher prescriptions – they disguise the lens edges

fashionistas

sensitive souls who don’t like the nose pads on metal frames

Not ideal for – Petite faces – they can overwhelm you

Chubby cheeks – the lack of nose pads mean they can rest on the face

Metal frames – a chic, minimalist look, with slimmer rims.

Perfect for – varifocals or bifocal wearers – adjustable nose pads give you the best

lens position

petite faces

colour phobics! The colour is less obvious than with a plastic

Not ideal for – sensitive skin, many metal frames are made with nickel silver, which

can provokes a reaction

high prescriptions – you’ll see the lens edges and all the weight of the

heavier lenses is focussed on the small area of two little pads.

Rimless – the pared down minimalism of bridge and side arms gives an almost invisible look.

Perfect for – anyone who hates wearing glasses! They are less visible than

conventional frames.

Anyone who wants to design their own glasses – you can have the

lenses cut into any shape you fancy!

Not ideal for – High prescriptions – the lens edges are visible, so thickness will show.

The heavy handed – these specs are more vulnerable than any other,

and the bit that breaks will usually be the lens, which is the expensive

part!

So that’s the easy bit, the practical pros and cons of each broad spec style. Now you just have to work out what shape, what colour, how thick the sides should be……..

Life in 3D

Friday, March 4th, 2011

Technology moves at a swift pace, and from the early days of wonky plastic specs and magic eye pictures, we’ve come a long way in making 3D an important part of our daily entertainment. From the ground breaking spectacle that was Avatar, to the joy of Toy Story 3, 3D is gathering pace and fans! It’s not all excitement though – there have been some concerns raised over the safety of 3D, and potential problems with eyesight, so studies are ongoing within our profession to monitor any effects.

So far, you can rest assured that there is no evidence to suggest that 3D can cause long term harm to viewers. They may even have a positive effect in bringing to light slight visual problems that the patient has been suffering with but have not been diagnosed. If you watch 3D and suffer any visual problems or headaches then it may prompt a visit to the optician, where double vision or undetected short or long sightedness can be corrected. These ‘eye-strain’ type symptoms have been reported by viewers, but it’s usually a short term problem.

The launch of the Nintendo 3DS portable gaming system has worried many parents, concerned over possible damage to children’s sight. The advice at present is that again, there’s no evidence to suggest problems. Parents should however note that like any other system children should not use them excessively. Hand held consoles are closer to the eye than 3D TV or film, and kids may watch them for longer, so frequent breaks are advised. The short focal distance to the screen of a game means the child has to focus harder, so eye-strain is a potential problem. Healthy outdoor sports, where you focus far away help the eye’s optical systems to develop properly, so a mixture of hobbies is the best way to offset any potential overuse of hand held games.
