Is It Safe To Wear Colored Contacts?

Q1. Are contact lenses dangerous?

Countless people wear contact lenses every day. Some first-time contact lens wearers worry that the lenses will slip behind their eyes. Please rest assured that this will not happen. However, you should be aware that contact lenses are medical devices. Therefore, they must only be prescribed and dispensed by an eye care professional. There have been cases of people who have suffered eye injuries from wearing novelty “Halloween” contact lenses.

Q2. Cosmetics and contact lenses: can you only choose one or the other?

Cosmetics and contact lenses can coexist harmoniously as long as you are careful when using them. We recommend that you wear contact lenses first. This will prevent the oil and other substances in cosmetics from getting on your contact lenses. Also, be sure to wash your hands before touching your contact lenses, and do not use heavily scented moisturizing soaps when washing your hands. Using such soaps can lead to unwanted residue on your contact lenses.

These are common problems encountered by first-time contact lens wearers who want to switch to contact lenses. If you have any questions, be sure to consult with your eye doctor, as many specific issues will vary from person to person.

Q3. What are the advantages and disadvantages of contact lenses compared to glasses?

It is important to consult with your eye doctor as the conditions of use and the environment in which they are used can lead to different discomforts in the use of contact lenses.


  1. Even people with high myopia will feel that their field of vision is wide and there is little to no strabismus or objects that look small.
  2. Even if there is a large difference between the degrees of the left and right eyes (different refraction), it can be fully corrected.
  3. There is no blurring of lenses due to rain or heat, etc.
  4. Soft contact lenses have the feature of not falling off easily even with intense movement.
  5. Soft contact lenses that are replaced once a day come in boxes of 30 lenses, and soft contact lenses that are replaced once every 2 weeks come in boxes of 6 lenses. You can replace them even if you lose them, so there is no need to worry.
  6. Will not change the wearer’s appearance.

Disadvantages and Precautions

  1. There is a risk of eye disorders if contact lenses are not used correctly. (Regular examination by an ophthalmologist is required)
  2. Contact lenses should not be used in dry conditions or in environments where dust or drugs can easily enter the eyes.
  3. People with eye diseases, such as those with extremely low amounts of tears or allergies (allergic hay fever, etc.), may not be able to use contact lenses.
  4. For cases where contact lenses cannot be used, it is recommended to prepare glasses as a backup.

Q4. Why do I need glasses when I already use contact lenses?

When the eye is abnormal, etc., there may be a situation where contact lenses must be temporarily removed.

In such cases, glasses are needed. In addition, using contact lenses for a long period can be difficult for some people, so it is recommended to have glasses as a backup.

To rest your eyes as much as possible, it is also necessary to use them with glasses for short periods.

Q5. Can contact lenses break in my eyes?

Generally speaking, contact lenses hardly ever break during daily wear. However, since contact lenses are made of thin plastic, they can break in the eye in the event of an external impact, such as a ball hitting the eye. In the case of soft contact lenses, the lens can bend in the eye. If a contact lens breaks or bends in your eye, please go to an eye clinic to have all of them removed.

Q6. Will myopia increase with glasses and contact lenses?

Some people often say that wearing glasses will worsen myopia and that wearing contact lenses will not worsen it too much, but this is not true. When myopia worsens, both glasses and contact lenses will worsen equally. However, it is not because of wearing glasses and contact lenses that my myopia worsens. Whether myopia worsens or not is influenced by a variety of external circumstances, such as often looking at objects up close.

In addition, wearing hard contact lenses can result in a change in the degree of myopia and astigmatism. This is because the cornea (the part of the black eye) is slightly distorted by the pressure of the hard, rigid lenses. It will return to its original shape without the use of hard lenses.

Q7. Do I see better with a higher prescription?

It is wrong to say that the deeper the prescription of contact lenses and glasses, the clearer you can see. You can see best with contact lenses that are perfectly suited to your nearsightedness, farsightedness, and astigmatism. Deeper prescriptions also do not improve vision. When correcting myopia, if you go higher than the proper prescription, you will instead become farsighted.

This is called (myopia) overcorrection. Instead of seeing clearly, it becomes difficult to see up close or becomes a cause of eyestrain.

In addition, the above-mentioned perfectly appropriate prescription is the clearest one, but it is not limited to the one that is most comfortable to wear. The right prescription for each person is different depending on age, living environment, work content, etc. Please decide on the prescription after careful communication with your ophthalmologist.
