In the world of students, are there any students without glasses? If there is, hurry up and let me envy you! I’m not going to lie, I’ve been nearsighted since the 5th grade, from 200 degrees at the beginning to 800 degrees now, so I’ve been wearing glasses for over ten years. Like my last glasses, buying prescription glasses was expensive, but it cost me $500! After all, my prescription is high, and the requirements for prescription lenses are gradually increasing; the consequence is that my wallet is directly “deflated.”
Where there is oppression, there is resistance, can not let their wallets suffer, so I began to buy glasses online. The following talks about the process of buying glasses online!
Offline eye examination
This is a necessary step, mainly to test the prescription of myopia and astigmatism to find the most suitable for their degree. The general optometry store is the first professional machine to measure the degree and then change the test lenses to let you adapt for a while; look at the vision table. Special reminder, if you can not see or are especially blurred must be the optometrist speaking, do not be shy! Find the right lens, then it is with it all over the place, mainly to see whether the dizzy, clear, or not. If the above is not the case, then congratulations, you found the right degree of lenses for yourself!
Honestly, our general myopia students do not have to refer to the mirror eye distance, eyebrow height, leg length, and other such parameters that make people head, and we are mainly concerned about myopia and astigmatism on the degree of entirely OK!
Choose lenses and frames.
Most of the prescription lenses on the market today are resin lenses because the material is really light but also very wear-resistant; they will not use for a week or two on the lens is scratched phenomenon.
First of all, a little knowledge, the greater the refractive index of the lens, the lighter and thinner the lens; the current specifications of the lens is divided into 1.49 (basically eliminated), 1.56, 1.61, 1.67, 1.71, 1.74, of course, 1.49 this specification is basically eliminated, not to hide from you, I am 800 degrees of high myopia, before also used 1.56 it, really thick so you can not imagine I’m now on both sides of my nose are still pressed down by them pits it!
Lenses are thin, natural, light, and comfortable; it is also said that people are naturally costly! Before, my index 1.56 prescription lenses cost more than 100 dollars; now, with a refractive index of 1.74 directly to 500, of course, if you have a low degree, not so expensive.
The choice of frame is much easier; you like it, of course; good-looking is the kind of metal material, giving a sense of style, but it is a little heavy, high degree of the original lens is thick; I still do not recommend. Want a little lighter, why not choose titanium or plastic, light material, do not worry about the nose bridge pressure out of the marks.
The critical issue is that most online prescription glasses are of good quality, which means that cheap glasses online are of high quality, perfectly acceptable, and less low quality than others say.
