Tokai Progressive Lens

TOKAI PROGRESSIVE LENS

Progressive lenses have turned into a popular lens design that is commonly worn by people nowadays. Especially for those already present with glasses to look at the distance since young and they also start getting blurry vision when reading or looking at computer screens when they are entering the age of 40. Progressive lenses are convenient, it eases the user, with only one glass, able to access vision through all distances, way far better than having 2 separate glasses where users have to switch between them when looking at distance and look at near. 

However, a good progressive lens is very important, as it helps the users to make their daily work to be completed much more effectively and reduce the work stress. To ensure progressive lenses come with maximum comfort and are stress-free, TOKAI introduces the RESONAS, an all-new progressive lens design using the neuroscience technology – analysis of the brain wave.

Neuroscience Technology

NEUROSCIENCE TECHNOLOGY

The design is developed from the E.N.Spiral Model which uses neuroscience to repeatedly test the lens.

TOKAI invented this new design with both the front and back surface of the lens being a progressive design, an additional combination with the use of an aspheric lens. Incorporated neuroscience technology, allows the evolution of RESONAS inner surface progressive addition lens. The double side progressive and double side aspheric made to balance the far, intermediate and near vision, maximising the comforts when switching distance. It also decreases the distortion, giving a better peripheral vision, makes the sight even clearer and wider. 

b) RESONAS

Progressive design lens incorporated with neuroscience, a neurologically pleasing fit. TOKAI RESONAS with the design of backside progressive and backside aspheric perfectly suits customers who want more than just a progressive lens. The neurological design is developed under the concept YES/NO, NO = brain in Japanese, YES = rejoicing, in pursuit of the extremely simple but important comfort fitting. This contributes to the optimization in fuzziness, distortions and movements, and leads to a better fitting. RESONAS neuroscience design and monitoring based on ergonomics, measures and analysis of the brain waves, led to the uprising of progressive addition lenses, even pleasing to the brain.

How to read your contact lens prescription?

Most of you must wondering on ‘how to read your contact lens prescription?’

Your contact lens prescription allows you to purchase contact lenses that match your requirements from optical shop or online suppliers.
You need to know your physical prescription with you in order to purchase contact lenses from physical or online shop and also you do need to have a good understanding of what it is. How to read your contact lens prescription? You can find your prescription on the piece of paper given to you by an optician during a check-up. However, contact lens prescriptions can vary in number depending on the brand of the product itself.
A written prescription usually includes the following specifications: base curve, diameter, power (or sphere), and then additional figures for Cylinder and Axis if you have astigmatism, and Addition and Dominant figures for presbyopia correction. The prescription for your left and right eye will be listed separately as they may vary.

What OD and OS mean
The first step to understanding your eyeglass prescription is knowing what “OD” and OS” mean. They are abbreviations for oculus dexter and oculus sinister, which are Latin terms for “right eye” and “left eye.”
Your eyeglass prescription also may have a column labeled “OU.” This is the abbreviation for the Latin term oculus uterque, which means “both eyes.”
Though use of these abbreviated Latin terms is common on prescriptions for glasses, contact lenses and eye medicines, some doctors and clinics have opted to modernize their eyeglass prescriptions and use RE (right eye) and LE (left eye) instead of OD and OS.
On your eyeglasses prescription, the information for your right eye (OD) comes before the information for your left eye (OS). Eye doctors write prescriptions this way because when they face you, they see your right eye on their left (first) and your left eye on their right (second).

What does each prescription figure mean?

  • Base Curve (BC): The base curve determines what type of fit is required for the lens to meet the curve of your eye. This is usually written in millimeters or sometimes with the words: flat, median or steep.
  • Diameter (DIA): The diameter of the contact lens is also written in millimetres and determines the width that best fits your eye.
  • Power/Sphere (PWR/SPH): This figure shows whether you are long or short-sighted and how much correction your eyes require. If you are long-sighted your figure will begin with a + (plus sign) and if you are short-sighted it will begin with a – (minus sign). This will be followed by a number that goes up from 0 in measures of 0.25 dioptres, the higher the number the stronger the visual correction needed.
  • Cylinder (CYL): The cylinder will always be a minus number that increases in measures of 0.25. Much like the power/sphere figure that is shown on all standard prescriptions, the cylinder denotes the extra visual requirements needed for astigmatism and how severe the astigmatism is.
  • Axis (AX): Astigmatism is caused by the irregular curvature of the eye; the axis is a figure which determines the angle of the correction needed in order to see clearly. The Axis is always a number between 0 and 180 degrees.
  • Addition (ADD): If you suffer from presbyopia it affects your near vision, the Addition figure determines what level of correction you need to be able to see clearly at a close distance. This is a number between 0.50 and 3.00, some contact lens brands refer to this as a high, medium or low.
  • Dominant: If you wear multifocal contact lenses or bifocal contact lenses, the correction is determined by a dominant and non-dominant eye, this is the dominant figure usually marked with a “D” and “N” to express which eye is which.

An eyeglass prescription cannot be used to buy contact lenses

Eyeglass and contact lens prescriptions aren’t the same. An eyeglass prescription is for the purchase of eyeglasses only. It does not contain certain information that is crucial to a contact lens prescription and that can be obtained only during a contact lens consultation and fitting.
In addition to the information in an eyeglass prescription, a contact lens prescription must specify the base (central) curve of the back surface of the contact lens, the lens diameter, and the specific manufacturer and brand name of the lens.
Also, the power of an eyeglass prescription frequently is modified when determining the best contact lens power. This is because eyeglass lenses are worn some distance (usually about 12 millimeters) from the surface of the eye, whereas contact lenses rest directly on the cornea of the eye.
An accurate contact lens prescription can be written only after a contact lens fitting has been performed and the prescribing doctor has evaluated your eyes’ response to the lenses and to contact lens wear in general. Let’s make an appointment with us at Malaya Optical Optometrists, we are ready to teach you on how to read your contact lens prescription!

5 things about multifocal contact lenses

In this article, we will explain 5 things about multifocal contact lenses which can helps people see clearly across a range of distances, and are often used to correct presbyopia. Multifocal lenses bend light to more than one focal point on the retina. This is how they compensate for refractive errors affecting near, intermediate, and distance vision. Many people with presbyopia choose to wear multifocal contact lenses rather than juggling two pairs of prescription glasses. Today, there are various multifocal contact lens options are available, so let’s know more about multifocal contact lenses that are best for you.

Here are the 5 things about multifocal contact lenses you should know:

1. What are multifocal contact lenses?

Multifocal contact lenses are made with different lens powers, targeting vision at varying distances from the wearer. Basically, they are contact lenses with multiple prescriptions in one lens. This all-in-one lens benefits people with presbyopia by helping to correct age-related vision problems – when their eyes can no longer focus on objects up close. As we age, it becomes more difficult for our eyes to focus on nearby objects. Many people need one prescription to read and another to see things farther away. Multifocal contacts are a popular option for dealing with presbyopia.

2. How Multifocal Contacts Lenses Work

Multifocal contacts are wonders of optical engineering that provide more than one prescription power in a single lens—no small feat. This is accomplished with a complex structure that brings light to different focal points depending on where it enters the lens. Consumers have several types of multifocal contacts to choose from, including:

Simultaneous Vision: There are two types of simultaneous vision lenses. The concentric design features alternating powers arranged in concentric circles. The aspheric approach gradually changes the prescription as you move outward from the center of the lens. Your brain learns to pay attention to the part of the lens that provides the clearest vision in a given situation.

Segmented Vision:  A distinct border separates each prescription, similar to the design of bifocal glasses. In order for segmented lenses to work properly, your pupil must be able to move beneath them so you can use the proper prescription. This is accomplished with a simple design tweak: when looking down, the bottom of the lens gently touches the lower eyelid, pushing the lens back towards the center of the eye.

3. What’s the difference between multifocal and bifocal contact lenses?

Multifocal contact lenses have a smooth and gradual transition between the prescription for reading and seeing things close up, the prescription for normal distance, and viewing things far off in the distance – very much like progressive eyeglasses. Bifocals, on the contrary, have an abrupt difference in the line between the near and normal vision prescription areas of the lens.

4. What are the types of multifocal contacts?

Multifocal contacts are available in both soft and rigid gas permeable (RGP or GP) lens materials and are designed for daily wear or extended (overnight) wear. Soft multifocal lenses can be comfortably worn on a part-time basis, so they’re great for weekends and other occasions if you prefer not to wear them on an all-day, every day schedule.

For the ultimate in convenience, one-day disposable soft multifocal lenses allow you to discard the lenses at the end of a single day of wear, so there’s no hassle with lens care.

In many cases, GP multifocal contact lenses provide sharper vision than soft multifocal contacts. But because of their rigid nature, GP multifocal contacts require some adaptation and are more comfortable if you condition your eyes by wearing the lenses every day.

Hybrid multifocal contacts are another option for clear vision at all distances after age 40. These lenses provide the clarity of gas permeable contacts and the comfort and easy adaptation of soft lenses.

5. Choosing multifocal contact lenses

The most important thing to know when choosing multifocal contact lenses is communication with your eye doctor. Your eye doctor will need to know about your lifestyle, hobbies and regular activities, what your prescriptions are and will then be able to go over the options which are best for you. Visit to your eye doctor for consultation, book your appointment with us at Malaya Optical Optometrist.
