Wearing glasses correctly will not get deeper degrees
The development of myopia is not directly related to wearing glasses. Patients with myopia wear suitable glasses and pay attention to eye hygiene, and the degree of myopia will stabilize at a certain level. But if you think that with glasses, everything will be fine. If you don't pay attention to eye hygiene in normal times, if you continue to keep your eyes in a state of fatigue for a long time, it will lead to vision loss and deepening of myopia. In addition, wearing improper glasses such as no optometry or inaccurate optometry, too large power, will increase the burden on the eyes, reduce vision and deepen the power. For some people with high myopia (more than 600 degrees), although they insist on wearing glasses, the degree will still deepen, accompanied by changes in the fundus, which is medically called pathological myopia. This deepening of myopia is related to the degree of myopia and family and has nothing to do with wearing glasses.
The Advantages of Single Vision Lenses
As is well known, single vision lenses can be used to correct your vision so that they can restore your ability to see clearly.
Single vision lenses can boost the overall quality of your life with improved visual health and acuity. Single vision lenses can also help relieve you of eye strain and ensure fatigue and migraines.
Besides, single vision lenses will help to protect your eyes from impact, trauma and common irritants like dust, sand and insect.
Semi-rimless glasses are easier to clean and maintain
Semi-rimless glasses usually have only half of the glass frame. We tend to wipe our glasses in one direction, but we all know that the glasses are all wrapped up. So when some small particles appear on our glasses, these things can not be wiped out by the glasses cloth, and it is easy to scratch the lens. This is one of the drawbacks of full-frame glasses.
How to choose progressive lenses
The progressive lens can effectively control the deepening of myopia, but there is no reliable empirical evidence. At present, the height of the lens frame is only about 30mm. The distance from the design of the transition interval is not enough, and the comfort of the eye is difficult to adjust the short distance. From the quality and technology, the foreign brand design process is stable and mature, but the price is too high, there are still a lot of people who are not easy to adapt. The parameters of progressive lenses need to be determined by strict optometry.
Square face with round glasses
The square face belongs to the type of facial lines or tough, which looks a bit unnatural. For this type of face, it is best to choose round glasses because a round shape can make your facial lines softer and add a little femininity. The most suitable glasses for a square face are round, but the size of this round is also very particular. If you have a wider face, it is better to choose larger glasses, which can better modify the face and make the face smaller.
Marc Walks pure titanium rimless glasses
The detailed processing lets you experience the perfect quality. They areβ titanium pure titanium ultra-light rimless myopia glasses, the new silica gel temple tips, and rivet design, and they will not deform with many twists and turns. The silicone material is safe and non-toxic. They have a non-screw design, so installation is not loose, and the lens is stable and not shaking. The lens is not in direct contact with metal and is not easy to break. The degree is not limited, so 1500 degrees below can be installed.
Why do spectacle lenses fog up?
The fog on the surface of the lens is essentially related to the saturation pressure and water vapor liquefaction. The air is full of water molecules, which are constantly doing irregular movements. When there is no temperature difference, water molecules keep hitting the surface of the lens and will keep bouncing off. The lower the temperature, the slower the speed of movement. Therefore, when water molecules hit the cold lens from the hot air, on the one hand, they move too slowly to fly out in time. On the other hand, because of the relatively low temperature of the lens itself and its vicinity, the water vapor will liquefy. As a result, more and more water will accumulate on the lens and form small droplets, eventually forming a foggy layer. As the lens heats up, the mist evaporates back into the air, and the fog disappears.
