1. Contact Lens come in various size in Ryocon. Are they suitable for everyone?

Every individual's eyes are different, so does the curvature. That is why not every design fits everyone. For example people with little eye white will have difficulties wearing contact lens with diameter 14.80mm.

2. After wearing the black lens, will it look unnatural?

If you naturally have many eye white part, black lens will look very natural on your eyes. As black lens are more subtle, even without make-up, black lens will look quite natural on you. If you have very little eye white part, black lens will look abit unnatural, black lens with small diameter (14.0mm-14.2mm) is advised for normal size eyes.

3. I have very small eyes, can I wear your company's contact lens?

Certainly yes. We have contact lens from size 14.0mm to 15.0mm for you to choose from. If you have no experience with wearing contact lens, we advise you to book an appointment with eye-specialist  to learn the correct way to wear and remove contact lens. This is highly recommended.

4. How to read contact lens  data?

BC= Base Curve

DIA= Diameter

PWR= Power

CYL= Astigmatism

AXIS= Direction of astigmatism

These data are usually written at the side of box or on top of packaging.

5. What is Power?

Power here refers to shortsightedness. it is usually in this form ( -2.00 ) . Throughtout this website, we made it simple by just writting numbers only, for example 200 instead of -2.00. It is assumed that customers understand the color lens are for short-sighted correction only.

6. Are the color lens soft or hard contact lens?

All color lens sold in this site are soft contact lens. 

7. Can I wear soft contact lenses if I have astigmatism?

Astigmatism of 1.50 and above are strongly advised to not wear ordinary color lens. Normal soft contact lens are unable to correct astigmatism. Astigmatism users should use toric contact lens instead. This might be available in Ryocon in the near future.

8. What does Base Curve (B.C) mean?

The base curve or radius (BC) describes the curvature of the lens.

9. What does diameter mean?

The diameter (often abbreviated to DIA) is the size of the lens measured from edge to edge.

10.  Where can I find my presciption data?

You can find your parameters on the paper copy of your prescription, or on the box containing your lenses. You will find details of the power/strength/sphere (SPH), base curve (BC) and diameter (DIA). If you have astigmatism you will also find an axis (AX or AXIS) and cylinder (CYL).  If in doubt, please contact us.

11. Which colored lens is suitable for me?

All color lens are carefully selected by staffs and we have all worn them before putting them into market. Whether you like obvious or subtle effect, light or deep color, we sure have something for you. Please book with us a free appointment, and our staffs will give you advises on choosing the color you want.

12. Why toric lens with color is not available?

Coloured toric lenses are available (although not in Ryocon's range currently), but they are not very common. Since the demand is not very high most contact lens manufacturers have concluded that it is too expensive to produce coloured toric lenses.

 Lens Wear FAQ

1. Can I wear the lens straight after I opened it ?

For vials, it is recommended to soak the lens in case using multi-purpose solution for at least 2 hours before putting them in eyes. For blisters, you only have to wash the lens with multi-purpose solution for a few times , and you are ready to go.

2. My eyes feel dry all the time. What can I do?

There can be many reasons for dry eyes, and you will often need to try out different types to find a good solution. Sometimes changing your contact lens solution or changing to a contact lens with lower fluid content can help. The lenses that usually work best for dry eyes are the new silicon hydrogel lenses, for example Barbieeyes.

You can also use eye lubricating drops (suitable for contact lens use) to moisten your eyes. Due to environment issues, one's eyes can get dried up easily. We recommend you to use Rohto eyedrop to moisten your eyes.

3. My vision is blury after wearing the color lens. What is the problem?

This can be due to many reasons. First, make sure the power you purchased is correct and you'd checked your eyes quite recently. If you are not sure, have a eye test again. Remember it has to be contact lens prescription, not eyeglases prescription as they are different.

Second, protein built up on surface on lens. Make sure you clean your lens everyday with the correct solution. Soak lens in cases for at least 2 hours before reinserting.  Use saline to clean off debris each time before you wear. 

Thirdly, your iris might be bigger than normal person and the color parts of conlens has blocked your vision. In this case, we would advise you to choose a color lens that has minimum center coloration, eg. Ringo Black, Super ring etc.

4. Contact lens does not stick to my eyeball.. It keeps shifting!

Once you'd inserted contact lens into your eyes, make sure it is centered. Close your eyes and press your eyelid softly to remove any air bubble on lens. Otherwise, make sure your B.C is in the range of 8.4~8.6 as this is the common B.C in Ryocon color lens range. If not, the color lens might not fit on you eyeballs.

A big size contact lens may have difficulties shifting in small eyes. Take extra attention when you choose your contact lens.

The optician will also show you how to care for and handle your lenses in the right way.

12. I feel like something is poking my eyes when I wear contact lens. What happen?

If you feel stitching pain, please remove the contact lens immediately and place it in contact lens case. Make sure the solution you used is not strong (like ozone-based ) and if you'd used extra strong solution to clean your lens, please soak them in mild multi-purpose solution before wearing them again. Use saline to wash off the strong solution and when the pH of lens is diluted by saline it is safe for your to wear again without any pain.

Also, check for any tear orchip-off on lens. This might be due  chip-off caused by improper care.

For manual on how to wear, clean and store contact lenses properly, please refer to our manual.

1. Can I buy any solution from pharmacy shops? 

Please be caution when you choose solution. The most common solution is  " Multi-purpose solution"  . Make sure your solution is compatible with hydrogels contact lens. Do not use saline to soak lens as saline cannot remove protein effectively.

2. My vision is clear when I first wore them, but as time goes on, my vision gets more and more blurry, why does this happen?

Protein builds up on lens surface very quickly. Customers are advised to use "Protein removal pills" to remove the protein on lens surface twice every month. However, vision blurry might be dued to an increase or decrease in eyesight power. Please have regular check-ups with your eye-specialist.

3. Which bacteria, fungi and amoebae colonize lens, and what can they do?

Many different microorganisms are capable of producing side-effects in conjunction with contact lenses. The most serious side-effect is infection in the cornea. If bacteria are present on the lens, this need not mean that you will get an infection, although the risk will increase. Bacteria on the lenses can also cause inflammation in the eye. That is why it is always important to ensure good hygiene and to follow the cleaning and disinfection instructions closely. With the fewest possible bacteria on the lenses and in the storage case, the risks of infections and inflammations will reduce.

The Pseudomonas bacterium, for example, is capable of producing severe infections, which in the worst case can lead to serious visual impairment. Fungi (e.g. Candida) rarely cause infections in the cornea, unless the individual is already in a poor general state of health or has an immune system deficiency. However, they can grow on the lens and destroy it. Mould fungus also occurs when the lenses have been left standing too long in a fluid without preservative. The most feared and treatment-resistant infection is caused by Acanthamoeba. This is a single-celled organism that occurs naturally in the soil, water, etc. It is a very rare infection, but it is highly resistant to treatment and almost always leads to visual impairment or even blindness.
