Single vision lenses are created to help one field of vision; either short-sightedness, or long-sightedness. They are both very common and known as refractive errors. Refractive errors refer to a problem with the eye’s ability to focus light to the right part of the retina, which can often result in blurry or out of focus vision.
Myopia, otherwise known as short-sightedness, is an eye condition that can begin to develop during puberty and can get progressively worse until the eye stops growing. Myopia affects roughly 1 in 3 people in the UK. The signs you might have myopia include squinting, eye strain or headaches, and needing to sit closer to objects to see them more clearly. There has been research that suggests genetics play a part in myopia, a child is more likely to develop the condition if either or both parents also have it. It is likely that you’d need glasses for distance, or glasses for driving, if you develop myopia. It is usually diagnosed through a normal eye examination.
Hyperopia, sometimes also known as hypermetropia, long-sightedness or far-sightedness, results in objects nearby appearing blurry or out of focus, but objects in the distance are sharper. Adults can develop hyperopia with age, but age-related long-sightedness is usually defined as presbyopia. Children may be born long-sighted, but it often corrects itself. Your optician can offer the right advice if you think your child might be suffering from hyperopia.
If you notice a change in your vision, it could be that you have developed one of these eye conditions. The comforting thing is that both of these conditions are easily treated by wearing corrective lenses, such as spectacles or contact lenses.
Why having the right lenses is important
If you think you might need corrective lenses, it’s important that you see an optician and ensure you receive the right prescription lenses for your vision needs. An optician can not only check your eye health, but also assess your lifestyle or physiological needs, in order to prescribe the right type of lens.
Single vision lenses have been around for centuries, but their design hasn’t changed much over time. The same, however, cannot be said for our lifestyles. Both the way we live and our demands, have evolved. We live in a digital era with on-the-go lifestyles that demand straightforward results along with products that are easy to use and adapted to us.
When choosing the best single vision lenses for you, there are many different things to consider. Possibly the most important is your lifestyle and what you use your lenses for. For example, do you spend all day in front of a computer? Do you drive frequently or for long periods of time?
Understanding the benefits of single vision lenses
If you need single vision lenses, you might notice a change in your vision in not being able to see as clearly as before. However, there are other lifestyle-related issues to look out for.
Eye fatigue can be a huge problem. This is where your eyes feel tired at the end of the day. You might suffer from dry or itchy eyes too. This can often occur if your eyes are working too hard through the day to go about your day-to-day tasks.
Similarly, harmful light is becoming more of a factor for those looking to invest in single vision lenses. The potential dangers of blue light on our vision is a huge subject of debate. It is UV and Blue-Violet light that causes the most damage to our eyesight, both of which are emitted from the sun, while Blue-Violet light also comes from LEDs.
In other words, choosing single vision lenses isn’t just about being able to see clearly. It’s also important that the right precautions are taken to protect eye health too.
Essilor Eyezen lenses
Eyezen by Essilor delivers an advanced lens technology that provides increased comfort and acuity too. Eyezen lenses are designed to reduce and prevent visual fatigue, so your eyes don’t have to work as hard through the day.
Optical standards in reading distances and eye declination have evolved to meet the digital demands of our lifestyles, but most single vision lenses haven’t been designed with this in mind. With that being said, most single vision lenses are optimised for far vision only, despite frequently looking at digital screens close up.
Furthermore, Eyezen lenses include Eye Protect System, embedded into the lens itself. This can protect from harmful light including UV and Blue-Violet light, which is toxic for our eyes. Did you know that UV light is one of the leading factors of cataracts?(1)
