Tokai MYOGEN is an advanced spectacle lens developed for children with progressive myopia. It is designed not only to provide clear vision but also to help slow down the progression of myopia by managing peripheral defocus and suppressing excessive elongation of the eye axis.
As childhood myopia continues to increase worldwide, modern myopia management has become an important part of children’s eye care. MYOGEN by Tokai Optical Japan offers a premium, spectacle-based approach for parents and eye care professionals looking for a non-invasive myopia control solution.
What Is Tokai MYOGEN?
MYOGEN is a myopia progression control lens developed by Tokai Optical Co., Ltd., Japan. Unlike regular single vision lenses that only correct blurry distance vision, MYOGEN is specially engineered to help control how light focuses on the retina.
The main goal of MYOGEN is to help reduce the progression of myopia by suppressing axial elongation, which is one of the major structural causes of worsening myopia in children.
Why Myopia Control Is Important
Myopia is not only about needing stronger glasses every year. When myopia progresses, the eyeball often becomes longer. This is known as axial elongation. Excessive axial length growth can increase the risk of serious eye health problems later in life.
Progressive myopia may increase the risk of:
- High myopia
- Retinal complications
- Myopic maculopathy
- Glaucoma
- Early cataract risk
This is why early myopia management is important, especially for children whose prescription is increasing every year.
How Tokai MYOGEN Works
Tokai MYOGEN works using the principle of peripheral myopic defocus. In simple terms, the lens helps redirect peripheral light so that it creates a myopia-control signal, helping to reduce the stimulus for excessive eye growth.
1. Clear Central Vision Zone
The central area of the MYOGEN lens provides clear and sharp vision for daily activities such as:
- Reading at school
- Looking at the board
- Outdoor activities
- Sports
- Digital screen use
2. Peripheral Myopia Control Zone
Around the central vision zone, MYOGEN uses a special optical structure that helps control the direction of light entering the eye. This helps create controlled myopic defocus in the peripheral retina.
This design aims to:
- Slow down myopia progression
- Reduce axial length growth
- Minimize yearly prescription increase
- Support long-term eye health
Tokai’s Unique Honeycomb Microstructure
One of the most important features of MYOGEN is Tokai’s proprietary honeycomb microstructure. This structure uses small hexagonal lens segments arranged across the lens surface.
According to Tokai product information, MYOGEN features hexagonal micro-lens segments of approximately 600 μm, with around 300 μm spacing between adjacent segments.
This dense honeycomb structure is designed to reduce visual jump, blur, and discomfort when the wearer looks through different parts of the lens.
Benefits of the Honeycomb Structure
- Smoother visual transition
- Reduced peripheral blur
- Less visual jump
- More natural vision
- Improved wearing comfort
- Better chance of consistent daily wear
Why Comfort Matters in Myopia Control
For myopia control lenses to work effectively, children must wear them consistently. If the lenses feel uncomfortable, heavy, blurry, or visually disturbing, children may avoid wearing them.
Tokai MYOGEN is designed with strong attention to comfort so that children can wear the lenses for long periods during school, study, outdoor play, and daily activities.
Available in High-Index Lens Options
Tokai MYOGEN is available in high-index lens materials, including 1.60 index and 1.70 index. This is especially beneficial for children with higher prescriptions because high-index lenses can be thinner and lighter than standard lenses.
Benefits of High-Index MYOGEN Lenses
- Thinner lens appearance
- Lighter weight
- Better cosmetic result
- Improved comfort for long-term wear
- Suitable for higher myopic prescriptions
Premium Tokai Coating Technology
Tokai is well known for advanced coating technology. MYOGEN lenses are available with premium coatings designed to support children’s active lifestyle.
- Super Power Shield (SPS) Coating
Tokai’s Super Power Shield (SPS) coating provides excellent durability, scratch resistance, and easier cleaning. This is important for children who wear their glasses every day, this coating makes lens durable with less scratches.
- Blue Cut Coating Option (BCC P-UV)
MYOGEN lenses may also be available with a Blue Cut coating option, designed to reduce exposure to high-energy blue light from digital devices, and also P-UV for backside UV protection.
Optical Quality and ABBE Value
Optical clarity is another important strength of Tokai MYOGEN. Tokai highlights strong ABBE values for its MYOGEN lens materials:
- 1.60 index: ABBE value around 42
- 1.70 index: ABBE value around 36
A higher ABBE value generally means less chromatic aberration and better optical clarity. This helps reduce color fringing and supports more comfortable vision.
Clinical Evaluation of Tokai MYOGEN
Tokai has reported clinical evaluation of MYOGEN lenses in children aged 6 to 14 years. A 12-month clinical study compared MYOGEN lenses with standard Tokai 1.60 aspheric single vision lenses.
The study reportedly included:
- 174 children
- Age range: 6 to 14 years
- Follow-up visits at 6 months and 12 months
- Comparison between MYOGEN and standard single vision lenses
Tokai reported that children wearing MYOGEN showed slower myopia progression and reduced axial length growth compared with the control group. Children also adapted well and experienced clear, stable vision for everyday use.
Who Should Consider Tokai MYOGEN?
Tokai MYOGEN may be suitable for children who:
- Have increasing minus power every 6 to 12 months
- Have a family history of myopia
- Spend long hours reading or studying
- Use digital devices frequently
- Need a non-invasive spectacle-based myopia control option
- Require comfortable lenses for daily wear
MYOGEN vs Regular Single Vision Lenses
| Feature | Regular Single Vision Lens | Tokai MYOGEN Lens |
|---|---|---|
| Corrects distance vision | Yes | Yes |
| Designed for myopia control | No | Yes |
| Peripheral myopic defocus | No | Yes |
| Honeycomb microstructure | No | Yes |
| Axial elongation management | No | Designed for this purpose |
| Child comfort focus | Basic | Advanced |
Healthy Habits to Support Myopia Control
Myopia management is most effective when advanced lenses are combined with healthy visual habits. Tokai also highlights lifestyle habits that may help support children’s visual development.
Recommended Habits
- Maintain correct posture while reading and studying
- Keep at least 30 cm reading distance
- Use proper lighting while reading
- Spend time outdoors every day
- Take regular breaks during near work
- Follow the 20-20-20 rule during screen use
- Maintain a balanced diet
- Have regular eye examinations
Professional Fitting Is Essential
MYOGEN is not just a regular spectacle lens. Correct fitting is very important for achieving the best result.
For proper MYOGEN fitting, eye care professionals should ensure:
- Accurate refraction
- Correct pupillary distance measurement
- Proper fitting height
- Suitable frame selection
- Good frame adjustment
- Regular follow-up examination
Tokai MYOGEN lenses in Nepal are exclusively dispensed through optometrists experienced in myopia control management. Proper prescribing requires comprehensive assessment, including axial length measurement and other essential clinical parameters. These advanced myopia management lenses are not intended for routine dispensing through ordinary optical shops or general opticians.
