What you need to know before you start using contact lenses.

Be sure to go to the ophthalmologist before purchasing contact lenses.
Including our website, many people don't go to the ophthalmology department because they can easily buy contact lenses online these days. However, in order to use contact lenses safely, ophthalmologists must see a doctor.

First of all, why should I go to an ophthalmologist? That's because contact lenses are highly controlled medical devices, and they can cause eye problems and deterioration of vision due to improper use of contact lenses.

A common pattern is when you wear contact lenses that don't match your eye size, you get eye problems, choose the wrong degree, and your eyesight deteriorates. Have accurate measurements of the values required to select contact lenses, such as BC (base curve) and PWR (degree).

In addition, ophthalmologists can practice putting on and taking off contact lenses. It may seem easy at first glance, but if there is a problem with how to remove it, it can hurt your eyes. Please see an ophthalmologist so that you won't regret it later.

In addition, even if you use lenses safely and comfortably after you start using them, be sure to have regular medical examinations as well as regular contact lenses. Even if you don't feel any abnormalities, you may have eye damage or eye problems. To maintain eye health, be sure to have a regular ophthalmologist check-up and follow the ophthalmologist's instructions.

color contact terms that should be kept to a minimum before purchasing for the first time

Here's a brief description of the terms you want to know before you buy your first contact lenses.

☐ BC (Base Curve)
BC stands for the base curve, indicating how bent the lens is.If BC is small, the eyeball feels tight because of the tightness of the bending, but if BC is large, the bending is slow, so it is easy to deviate.

Generally, it is considered acceptable if the error with your BC is within ±0.2mm.The only way to know which BC suits you is to measure it at the ophthalmology department.

☐ DIA (Lens Diameter)
DIA refers to the diameter of the lens. Instead of measuring the lens by crushing it, measure the diameter in a dome shape.

☐ Colored diameter
The colored diameter is the diameter of the colored part of the lens. If you want to make your black eyes look bigger, you need to choose a contact lens with a larger colored diameter.

If you want to make your black eyes bigger, you need to choose one with a larger colored diameter. Note that even if the DIA (lens diameter) is large, the area of the transparent part will only increase if the colored diameter is small, and the black eyes will not look large.

the right way to choose contact lenses

Now that you know the basics of contact lenses, let's look at what criteria to actually choose contact lenses.

DIA is not too big.

If DIA (lens diameter) is large, the lens will not slip easily, so you can wear it steadily, but the cornea will be difficult to breathe, which will strain your eyes. Therefore, it is not suitable for beginners who are not used to wearing contact lenses for a long time.

The appropriate DIA depends on the size of the eye and the size of the black eye you want to show, but the average DIA size is 14.0~14.2mm.If you are lost, I recommend you choose this size.

the act of choosing the size and degree that suits one

As mentioned above, if you don't choose the size (BC: base curve) and frequency you see, you can cause eye problems, and in the worst case, you can lose sight.

One-day contact lenses are recommended until you get used to them.

I recommend disposable one-day contact lenses for ultra-beginners who have never worn contact lenses themselves, and for those who have school and work to wear contact lenses only on holidays.

One-day contact lenses do not require cleaning or preservation fluids to be maintained at no initial cost. It may be expensive, but it will save you time and effort to take care of it.

From a safe point of view, it is ideal to start with a one-day type and gradually use long-term contact lenses.
