Lens Treatments | Options and Benefits

When you buy a new pair of glasses it’s not just the frames that come in a myriad of options – these days your lenses can be ‘upgraded’ with various tints, coatings and treatments. But there are so many it can all be a bit confusing – let us break down the most common options and the benefits they bring:

Anti-Reflective

Anti-reflective coating (also called AR or anti-glare) is perhaps the most commonly offered lens treatment, and with good reason: AR coatings not only benefit vision and reduce eye strain, but they can also improve your communication skills! That’s because they make the lenses in your glasses look nearly invisible, so people can see your eyes and expressions more clearly, and you can make better eye contact with them.

An AR coating virtually eliminates reflections from the front and back surfaces of your lenses, meaning more light passes through, allowing your eye to receive a higher percentage of the actual light available – up to 99.5 percent. This means less glare, sharper vision and greater comfort. AR coatings are also a good idea for sunglasses, because they eliminate glare from sunlight reflecting into your eyes from the back surface of tinted lenses when the sun is behind you.

As an additional benefit, most anti-reflective treatments have a special layer that prevents spots and makes them easier to clean, although any scratches do tend to be more obvious on AR coated lenses, so be sure to only use products and cleaning methods we would recommend!

Photochromic

Photochromic lenses automatically darken in bright sunlight (triggered by ultraviolet radiation) to make your eyes more comfortable. Because UV rays penetrate clouds, photochromic lenses may darken on grey days as well as when it’s sunny and they will not darken inside a vehicle because the windscreen glass blocks most UV rays. However, some newer types of photochromic lens activate with both UV and visible light.

An added benefit of photochromic lenses is that they shield your eyes from 100 percent of the sun’s harmful UVA and UVB rays and because exposure to sunlight and UV radiation has been associated with cataracts later in life, it’s a good idea to consider photochromic lenses for children’s eye wear as well as for the spectacles of outdoor-loving adults.

Polarized

Polarized lenses are anti-glare and virtually eliminate bright light from reflective surfaces and so are especially popular with fishermen and sailors.

Scratch-Resistant

Untreated lenses are surprisingly fragile, and it’s very easy to scratch them by storing them incorrectly, placing them down hastily or even cleaning them with some kitchen roll rather than the proper cloth! Luckily, lenses that are treated front and back with a clear, scratch-resistant coating have a much harder surface that is more resistant to scratching and more durable. It’s worth asking about this, because scratches are not only unsightly but can also seriously compromise the clarity of your vision. Nowadays some lenses have a built-in scratch-resistant coating, but double check that this is the case with your prescription.

Lots of options, then! Pop in a have a chat with us to choose that which best suits your lifestyle.


Back to School | Why Eye Examinations Are Important for Your Child

A survey last year by the Association of Optometrists showed a quarter of school-age children had not been taken for a sight test by their parents. But why is it so important?

Why do I need to get my child’s eyes examined?

Your child’s eye health is, of course, an important indicator of their overall health, but even if there are no concerns, regular eye examinations ensure your child has no vision problems that could affect their school performance and enjoyment of life. Early eye tests are important for several reasons: Not only because we need to ensure the visual skills that are essential for optimal learning are in place – a child who is unable to see what’s on the whiteboard can become easily frustrated – but also because children’s eyes are fully developed by the time they are 8 years old, so any problems must be detected before then. By demonstrating the importance of looking after one’s eyes we also help to create healthy habits that will hopefully mean your child continues to have their eyes tested regularly right through adulthood.

My child can’t read yet – how can you check their eyesight?

You don’t have to wait for your child to be able to read to bring them in for an examination – at Patrick and Menzies we have ways of testing that can be used with preschool children who cannot read, but even if you have no real concerns, we usually advise to bring them in for a full eye test before they start school just to make sure there aren’t any issues with their vision that could affect their early learning.

What should I be concerned about?

Once children start school it can be easier to spot the signs of a possible eye problem. If you notice any of the following, pop in and schedule an examination with us:

  • squinting
  • complaining of headaches or sore or achy eyes
  • hold books close to their face or sitting too close to the TV
  • problems with hand-eye coordination – being unusually clumsy
  • regularly rubbing their eyes
  • complaining that they can’t see the board at school

What can I expect at the appointment?

We’ll be able to work best with your child when they’re happy and alert – so for younger children an appointment straight after school when they’re tired and hungry may not work best, but generally an eye examination can actually be quite fun and interesting for a child. We have lots of different ways to check how well your child sees at different distances, but we’ll also check their eye movement, the back of the eye and how well they respond to light, amongst other things – our optometrists are experienced in making it a pleasant experience for your child and make sure your mind is at rest too.

Should your child need glasses we have an excellent range and are sure to have a style that will appeal, so do give us a ring or pop in to book your child’s appointment – that’s another thing you can tick off the ‘back to school’ to-do list!
