How to Choose and buy Myopic Movement Flasses the Choice Skill of Lens of Myopia Movement?
How does myopia choose motion glasses
1.Contact lenses + ordinary sports glasses
This is the plan that most people will choose, because it is simple, glasses style selection range is wide, cheap a treasure can be bought for dozens of yuan, but also a variety of color lenses can be interchangeable, foreign high-end brands of thousands of yuan is also a lot, completely depends on their economic strength.But the downside of this approach is that it's only suitable for short distances of running, hiking, cycling, and other activities, as contact lenses can cause a variety of hazards if worn for long periods of time.
Including: 1. A long time of breathlessness will lead to hypoxia of the eyeball, unable to normal metabolism and decreased resistance; 2.2. Easy to produce visual fatigue, and even cause dry eye disease, resulting in itching, foreign body sensation, eye excrement, dryness, burning eyes and blurred vision;3. Various substances secreted by glasses are deposited on the surface of the lens, breeding bacteria, causing corneal edema, corneal neovascularization reaction and allergic reaction, etc.;4. Can wear the cornea, may cause serious consequences of corneal epithelium shedding or perforation, resulting in irreversible vision loss;5. Long-term attachment to the eyeball, nerve endings will cause paralysis, resulting in decreased corneal sensation, many people appear ulcerative keratitis is still unaware;6. When the sand or sweat gets into the glasses during sports, the sour and cool can only be understood by those who have experienced it.Therefore, for the sake of the health of our eyes, and for our eyes to be more comfortable when we exercise, it is better to wear contact lenses as little as possible.
2.the inner frame of sports glasses myopia frame
The benefits of the scheme are the same price range is very wide, a treasure you can find a lot of choice, as low as 100 yuan of less than, high-end brand also has some can match its myopia box design, buy back frame, can be at a nearby store had compound myopic lens, can according to the demand situation, to choose collocation contact lenses or include myopia box.
However, this plan also has a big drawback, that is, sports glasses, especially cycling glasses, are basically designed to fit the face with a curved shape in order to achieve the windproof effect, so that the distance between the lens and glasses is very close. Under normal conditions, there is no problem, but now a layer should be forcibly inserted in the middle.Which causes our eyelashes to sweep back and forth across our lenses with the blink of an eye.Sometimes with the jolt of movement, the glasses shake and the lenses stick to our eyelids, leaving behind sweat and other debris.And because the space between the glasses and the face shrinks, when it's cold and sweaty or rainy, the lenses can quickly get a mist.All of the above will affect our vision and bring certain dangers to sports.
3.short-sighted sports glasses with windproof lenses
The principle is very simple, be equivalent to a pair of myopic glasses above all, next outer layer installs the windproof lens that can flip a lid, be like the sunglass clip that adds on the myopic glasses that we see at ordinary times, just this is sport version.
4.have a degree of swimming goggles + cycling glasses can clip myopia lens frame mirror
In long distance races (such as Ironman70.3 or Ironman Ironman Iron), riders may experience long battles and wear eyewear for hours during cycling and running, making the comfort of eyewear even more important.In particular, the choice of myopia lenses is the key to alleviating visual fatigue in long-distance cycling.
Five, myopic children can choose orthokeratology lens
Now myopia is getting younger, and many teenagers under the age of 18 are also suffering from myopia, but they love sports, so it is inconvenient to exercise with glasses on.And wear frame glasses once broken in the movement, the debris splashes into the eye or injury and facial tissue, it is difficult to find and remove.When you wear contact lenses for sports, you will often encounter dust or small particles entering your eyes, which can easily cause eye discomfort.In this case, myopic children want to exercise easily, orthokeratology lens is the ideal choice.
After wearing orthokeratology lenses for 8 to 10 hours at night, myopic people can remove them during the day.Because the lens produces slight pressure on the cornea, it will slowly change the shape of the cornea, flattening the central optical area of the cornea, thereby reducing the degree of myopia and astigmatism, improving the naked eye vision, and maintaining the vision of the whole day.
