Almost everyone's going to see it with glasses. The students' parties need to change their mirrors, the workers need to guard against the blue light, and the elderly need to be older and enter the glasses store, which opens with the following words: mirrors are made of national production, imports, and frame frames are ordinary, titanium, brand name plates。
Prices range from 300 to 2000 and are even more expensive, several times lower. A lot of people are groaning in their hearts: isn't that a glass with a frame? Why is it so bad? Is it really more expensive, or is it iq tax
Today, the distinction between 300 glasses and 2,000 glasses is clear and clear in the most tangible and common words. Tell you where the money is, who should buy the cheap, who must buy the expensive, and when they're done with glasses, at least half the money。
First, tell the truth: 90% of the money spent on glasses is in both
A pair of glasses, the cost structure is very clear:
- mirrors: determining clarity, comfort, eye-protective effects, over 60 per cent of the total price
- frames: determine weight, comfort, durability
- lighting + processing + door rental + services: hidden form
The difference between $300 and $2,000 is not “can we see it or not” but “can we see it for a long time, enjoy it, have no bruises and wear it properly”。
Following is a line-by-line comparison。
Mirror gaps: 300 and 2000, where is the core
1. Material and perforation: the eyes are tired
- three hundred
Most are common resin lenses, with a prevalence of 90%-92%。
During the day, the lights were clearly dazzled and luminous, the lights of the car, the street lights were scattered around and the driving and the night was not comfortable。
- 2,000
Most of these are high decomposition resins, high end membrane lenses, with a radiance rate of over 98 per cent。
Seeing things is closer to “naked-eyed realism”, light is soft, mobile phones, computers for a long time and eyes are not sour and dry。
In short:
The light rate is less, the eye is harder, and the fatigue is several times different。
2. Refraction rate: the higher the degree, the scarier the gap
The larger the refraction, the thinner the lenses。
- $300: most are 1. 56, 1. 60, normal refraction rates
- 2000 dollars: common 1. 67, 1. 74 high refraction rate
- less than 300 degrees: the difference is small, not visible in thin eyes。
- 500-800 degrees:
Cheap lenses are the bottom of a bottle, thick and heavy, crushing noses and slipping noses
Your glasses are half thin, much lighter, and you're wearing it all day long。
High-sighted people, precious lenses are not luxury, they're loss。
Membrane: shaving, anti-fouling, anti-blue light
The "film" on the surface of the lens is the sharp profit line。
- 300 lenses
- it's easy to scrape
- fingerprints, oil stains, dirty
- blue light protection, radiation protection, multiple foundation, general effect
- weak water protection. Rain and sweat. Hana
- 2,000 high-end lens membranes
- multi-layer membranes: shaving, grinding, anti-fouling, waterproof, static
- it's not easy
- it's clean. No prints
- formal blue light-proofing, filtration of harmful bands, non-yellow, non-coloural
- partly reflecturistic, uv-proof, more comfortable outdoors
Many people wear cheap glasses, and they feel fuzzy, obfuscated, dirty, not bad, but the membrane。
4. Optical design: normal sphere vs non-spherical/high-end non-spherical
- low-end lenses: sphere design
On the edge, things are deformed and twisted, and the more they get to the edge, the longer they get dizzy。
- high-end lenses: non-spherical, double non-spherical
The horizon is smoother, the residual light is not distorted, dizziness, adaptation faster and eye-friendly。
5. Branding and technology: it's not a brand price, it's a standard
The import of high-end lenses is expensive because:
- it's purer, less impurities
- production accuracy is higher, with minimal error in degrees
- there's a strict optical test. Every one of them
- multiple technology patents: protection against fatigue, gradual multi-focused, intelligent colour, etc
The 300-dollar lens meets the "read-out"
The 2000 lens is satisfied: comfortable, long-sighted, without injury。
Iii. Mirror gaps: 300 and 2000 with too many differences
1. Material diversity
- 300 frames
Most of them are: general alloys, plastics, tr90 low end feeds
- weight, nose, ears
- it's easy to paint and fade
- intensity, easy to bend. Break
- skin sensitive people. May be allergic, red, itchy
- a 2000 lens
Common: pure titanium, beta titanium, high-end plates, carbon fibre
- super light: it's only a few grams of titanium
- no paint, no sensitivity, no corrosion
- it's tough. It's hard to break
- nostrils, chainwork, no faces, no slips
It's 8-12 hours a day, 10 grams light, and it's completely different from the pressure on the spine and nose。
Work and detail
Your frame wins in invisible places:
- the chain's smooth
- the screws are solid. It's not easy
- nose nostrils, no crushes
- it's a lot tougher to look at
It's half a year for a cheap frame, it's a year for a change
Your frame has remained stable for 3-5 years, with low annual costs。
Iv. Sight testing and processing: some of the bad money is here
Many people only look at lens frames and ignore light + processing。
- low price glasses
- let's go. Five minutes
- the machine has a direct bill, no light, no pupil distance, no trial
- processor level, precision
- middle-high-end glasses
- integrated light detection: naked eyes, dispersive axes, dominant eyes, regulating functions
- the luminator will give you 10-15 minutes to make sure you're not dizzy or bitter
- high processing accuracy: high pupils, pupil distance, very small error in axis
The glasses don't match. They're cheap
It's perfect. Cheap lenses are comfortable。
No,
Real comparison: $300. Vs 2000 glasses. A watch
1. 300 yen glasses characteristics
- suitable: students temporarily changing mirrors, low near-sightedness, very limited budget
- advantages: cheap, short-term
- disadvantages: heavy, shaving-friendly, dazzling, comfortable
Life expectancy: about one year
2. 2000 yen glasses characteristics
- suitability: high-intensity, long-term computer, driving, sensitive muscles, durable use
- advantages: light, clear, comfortable, dry, insensitive
- disadvantages: expensive
Life expectancy: 3-5 years
3. Practical experience gap
- it's on in the morning: it's not that different
- to the afternoon: cheap start-up nose pain, ear pain, eye acid
- lights at night: cheap dazzling, expensive
- one year: cheap scratches, deformations, expensive as usual
Conscientious objection: should you buy 300 or 2000
For these categories, $300-500 is enough
- age, degrees rise every year, change every year
- low near-sighted below 300 degrees
- it's just extra glasses
- limited budget. Make sure you see it
Principle: sufficient, not unjust。
2. For these categories, it is recommended to go directly to $800,000
- over 500 degrees of near-sightedness
- over eight hours a day
- workmen, programmers, student parties, long-time watch
- always driving at night
- skin is allergic
- want to wear glasses for three to five years
For them, a little more expensive is the loss of eyes and body。
3. Right thinking with glasses
- mirrors: priority is given to the top-of-the-mill brand
- frames: light, insensitive, solid, not blind to big cards
- shining: precise, more important than expensive lenses
- don't be fooled. The more expensive, the less useless
Like when you don't look at computers, you don't have to put on the most expensive blue light
Vii. Write at the end: no glasses are the most expensive, only the best
The eyeglasses of $300 and $2,000 are not “can you see” differences, but differences in quality of life。
Cheap glasses to meet basic needs
Expensive glasses that make you easier to see, more comfortable to wear and longer to use。
Iq tax is either expensive or cheap。
It's a good choice to know how many degrees, habits, budgets you have。
The little thing with glasses affects your eyes and feelings every day。
It is more important than anything to step on the pit, not to be fooled, and to spend the money on the blade。
How much for your glasses
How long was it on? Have you seen the dazzling, dizziness, dizziness
Do you think lenses are important or more important
