What lens is suitable for me?

Finding the type of contact lens that suits your eyes and lifestyle is crucial for both your comfort and eye health.

    Nearsightedness

     

    How are you with road signs or movie screens? What about newspapers and labels? If you can see objects nearby with no problems, but reading road signs or making out the writing on the board at school is more difficult, you may be nearsighted. Your eye care professional may refer to the condition as myopia.


    Put simply, your eye is either too long, or your cornea is too curved (relative to the length of your eye). As a result, when light rays enter your eye, they’re bent too much - first by the cornea which acts as an outer lens and then by the actual lens inside your eye. The rays come into focus before they reach the retina - the part of your eye, which acts like a projection screen at the back of the structure. Therefore, instead of bringing images into one single focal point (like the bottom of a V shape) onto the screen, the rays cross (like an X) in front of it. This means they are split and diverging by the time they reach your retina.


    Therefore, that is what causes your blurred vision. The more powerfully your eye bends the light, the more shortsighted (myopic) you are. By contrast, the less your eye bends light, the more long-sighted (hyperopic) you become. Myopia is not a disease, it is an eye disorder, but that does not mean that you have “bad eyes”. It refers to a condition wherein the focusing power of the eye is too high in proportion to the length of the eyeball. This is typically treated with corrective lenses.

    Spherical correction works exactly how it sounds

    In the same way glasses correct your vision, contact lenses use spherical correction to help you see the world around you. It’s the first number in a prescription, often abbreviated as SPH, and it measures how powerful your contacts lenses need to be to correct nearsightedness or farsightedness.

    Farsightedness

     

    Trouble reading things close up but fine with reading at a distance? Does reading a book give you a headache?

    If so, you may be farsighted or have an eye condition known as hyperopia. The size and shape of the eye largely causes farsightedness. If you are farsighted, the cornea is not sufficiently curved or the eye is too short, so the light rays from close objects focus behind, rather than on, the retina when the eye is resting (not actively focusing on something).

    Farsightedness can cause the eyes to exert extra effort to see close up. Symptoms may vary depending on the amount of hyperopia. After viewing nearby objects for an extended period, blurred vision, headaches and eyestrain may occur. Other vision disorders can also contribute to these symptoms.

    Farsightedness isn’t a disease, nor does it mean that you have "bad eyes". It refers to a mismatch in the focusing power of your eyes in comparison to the length of your eyeball. The degree of variation will determine whether you will need corrective lenses.

    Presbyopia

     

    When you pick up a menu, do you have to move it away from you in order to see the text? Have you come to the point where your arm isn’t long enough for that trick to work anymore?


    The above scenario is a common telltale symptom of presbyopia. Unfortunately, as we get older, the lenses in our eyes lose some of their elasticity, and with this they lose some of their ability to change focus for different distances. The loss is gradual. Long before we become aware that seeing up close is becoming more difficult, the lenses in our eyes have begun losing their ability to change shape to help focus light rays. Only when the loss of elasticity impairs our vision to a noticeable degree do we recognise change.

    TOTAL1 Multifocal

    For oustanding comfort and seamless vision at all distances, near and far, try TOTAL1™ Multifocal contact lenses.

    Test123

    How do TOTAL1 multifocal contact lenses work?

    Unlike multifocal glasses that require you to look through the bottom part of the lens to read up close, TOTAL1™ multifocal contact lenses blend multiple prescriptions in one lens to allow your eyes to focus on objects at all distances. This Precision Profile Design™ combines a bi-aspheric surface, an adaptive minus power profile, and a centre-near design. This innovative technology allows these lenses to deliver uninterrupted transitions from near to intermediate to distance vision.

     

    This is sometimes also referred to as “simultaneous vision” because your brain learns to automatically select the right focus for what you want to see, so you can seamlessly see both near and far vision at the same time.

    Astigmatism

     

    Everyday moments a blur, everywhere you look?


    If your answer is yes, you may have astigmatism. It sounds like a scary word but actually having astigmatism is a pretty common condition; it’s not a disease and it doesn’t mean you have “bad eyes”. Astigmatism usually occurs when the front surface of the eye (the cornea) or the lens inside the eye isn’t completely even, causing the light rays to focus unevenly on the back of the eye (retina). This affects the ability of your eyes to focus and blurs your vision. If you've ever found wearing standard sphere contact lenses difficult, switch to toric contact lenses that are uniquely designed for astigmatism.

    What’s so special about toric lenses?

    The secret’s in the shape of the contacts. Most contact lenses are shaped like a semicircle with a spherical surface. But someone with astigmatism have corneas that look more like an egg than a ping pong ball. This is where toric contact lenses come into play! Imagine trimming the edge off the side of a doughnut – this creates a lens with several focal lengths to help your eyes refract light.
