Doctor’s schedule

For the beginners

Do you use contact lenses properly?

You might unconsciously get eye diseases if you do not use the lenses properly.
Here are some bad examples below.

Example1. Handling the contact lenses with dirty hands.

Even if your hands look seemingly clean, there might be bacteria or dirt on them.
They might cause some infections or allergies, so please wash your hands for sure before you wear/take off the lenses.

Example2. Wearing the contact lenses after applying makeup.

Cosmetic ingredients could also cause eye disorders. Please wear contact lenses before applying makeup to prevent them from getting stains.

Example3. Rubbing the eyes while wearing contact lenses

It might cause damages on the cornea if you rub your eyes with contact lenses worn. If you tend to rub your eyes a lot, that means there are possiblity of eye disorders. We recommend you stop using them and consult with the doctor.

Example4.Using the same contact lens case for a long time

You must completely rinse and dry the case to prevent it from growing bacteria, however, they might multiply inside even if you do so.
Therefore you need to replace the case every 1.5 to 3 months(soft contact lens)/6 months to 1 year(hard contact lens).

Example5. Sleeping with contact lenses in your eyes

You must take off the lenses before you sleep unless the doctor gives you a permission for the extended use.
There are less tear production during sleep and that make the eyes dry, which increases the risk of your eyes getting dameged by the contact lenses.
Please see ophthalmologists if the eyes condition is bad after you wake up.

Example6. Overwearing contact lenses

Please do not use contact lenses beyond the time period.
Contact lenses are made on condition that you use them properly, so the conjunctiva or cornea might occur inflamation if you do not follow the rules.
The symptoms are often chronic and get worse gradually, so it’s difficult to be aware of them. Sometimes your symptoms might suddenly become severe too. Be sure to follow the rules and use contact lenses properly.
If you have used contact lenses in a wrong way and have any symptoms or concern, stop using them and go to an ophthalmologist.

Do you know how to wear/take off and care contact lenses?
If you use the lenses in a bad way, you might unconsciously get eye diseases.

See a doctor before these disorders occur.

However, if you have any symptoms, please see a doctor as soon as possible.
