When purchasing color contact lenses with degrees, is there anyone who is worried about how to choose degrees?
When it comes to choosing contact lenses with degrees, the degree is a big point. You should be careful because contact lenses that do not match the degree may cause problems such as strange perspective or out of focus.
Here, we will introduce the structure of the degree of contact lenses and how to choose them in detail. Especially if you're purchasing contact lenses for the first time, please check them out!
Degree is important when choosing contact lenses with degrees!
Degree is important when choosing contact lenses with grade. The degree of contact is a number indicating corrective force. Positive values such as "+0.50" and "-0.50" are used for long-sightedness and negative values for short-sightedness, up to two decimal places. The farther away from zero, the higher the frequency.
The lower the eyesight, the greater the number, and the increase or decrease in 0.25 intervals. The upper limit of frequency is +5.00 and -12.00.The upper limit of the frequency varies depending on the product on sale and the brand of contact lenses, so let's check it out in advance.
In addition, you can measure the degree of contact = 0.4÷ vision. If you have 0.4 vision, you can calculate "-1.0" and if you have 0.1 vision, you can calculate "-4.0".If your eyesight is 0.05, 0.4÷0.05=8 and your degree is -8.0.However, this value is only a guide, so let's go to the ophthalmologist to check the correct value.
When you buy contact lenses, you also need to go to the ophthalmologist to measure how much of your vision is up to date and have it checked for the correct degree. If you are already using contact lenses and want new contact lenses, there is no problem with the degree of contact lenses you are using now.
If both eyes have different eyesight, you need to buy contact lenses of different degrees. It's expensive to buy one box at a time on the left and right, but if you use contact lenses that don't fit, you'll have problems with perspective and out of focus, so even if it costs a little, buy one that suits you.
Also, there are contact lenses that can be used by astigmatism. Although there are fewer kinds of contact lenses for astigmatism than for long-sightedness and short-sightedness, they are suitable for corneal distortion, so they can be used comfortably.
When choosing contact lenses, it is important to first know the correct degree. Form and design are important for contact lenses, but for comfortable use and eye health, check the degree of contact lenses first.
