Do you like glass and resin lenses

The Pink Tortoise Glasses lens has stable refractive index, good wear Rainbow Eyeglass Frame resistance and stable optical properties, but it is heavy and easy to crack. Glass lens: stable refractive index, good wear resistance, stable optical properties, but relatively heavy, easy to crack. Resin lens (CR-39) : Warner Sunglasses light, safe, high transmittance, not easy to crack, but easy to wear surface. PC lens: high refractive index, strong, but easy to wear surface. Reduce the lens degree (generally between 1.00D ~ 3.00D), strive to maintain comfort and binocular vision function. Use the lowest degree lens that can also correct myopia to the best vision. After fitting, it is recommended to try on the glasses for a longer time, so as to determine whether the Warner Glasses fit.

The ability of sunglasses to resist uv rays

 Eccentric piece: is the convex surface made of curvature uneven cross surface, so that the refractive index of light in the range of our eyes, so that our vision is clear and not dizzy, so as to achieve the pursuit of fashion while protecting our eyes.

Polarized Sunglasses For Sale lenses have shades of 15%, 34%, 50% and 70%. Fifteen percent of them can be worn indoors and outdoors. The Glasses Lens Index is required to be the most suitable strength, 34% suitable for ordinary outdoor environment, 50% suitable for the sun and the sea, 70% suitable for special purposes such as electric welding. The color depth of the High Index Lenses Meaning only affects the absorbance of visible light, and has nothing to do with the anti-ultraviolet ability. Uv resistance is only related to the lens material, space Transition Lenses is the best.

Sunglasses must be chosen according to the shape of your face

 It's summer, are you ready to go on vacation? Are you ready to go on vacation with Polarized Prescription Sunglasses? How do you choose Cheap Polarized Sunglasses that suit your face shape? Just write one. So our topic today is: How to choose Polarized Sunglasses For Sale that suit your face shape? As the name suggests, a round face is similar to an oval face in that it has no edges, but a shorter aspect ratio. Such as Zhao Liying and Michelle Chen. Round face, while cute and playful, is not a good partner for Women's Prescription Sunglasses. An important rule of thumb to make your face look small is to keep your lenses big enough. Whatever the shape, bigger shades distract the eye and make rounded faces look smaller.

What kind of glasses would you choose

 It is not recommended to use big brands, many of which are OEM factories in mainland China. The choice that picture wears wants to return colour Tortoiseshell Glasses and lustre to choose from material qualitative, design, this optional is very rich. It usually takes into account your age Transparent Clear Glasses, face shape and main purpose. I guess you are myopic, do not recommend the choice of low grade plastic frame and high bending frame such as aluminum magnesium Clear Frame Glasses, the former quality is very poor, the latter usually curved degree is very large, need prism compensation, and the vast majority of Transparent Eyeglasses shop will not calculate this degree. If you are around 30 years old, the TR90 will be lighter and the plate will be more fashionable (personal opinion). If the age is older, it is recommended to use titanium frame and so on.

Do your glasses fit you

 If the degree of the Eyeglass Lenses Online is not high, choose an ordinary Cheap Reading Glasses lens. Don't believe that the higher the refractive index, the better. If you face the computer for a long time, it is recommended to use anti blue light. If you want to go out often, you can choose color changing Buy Reading Glasses lenses. If possible, you can also choose moderate sun Reading Glasses For Sale lenses. If you are an adult flower, it is recommended to use progressive multifocal.

Your personal information is not rich and not very good suggestions. I hope you can provide gender, age, degree (myopia, old flower), purpose, etc. Generally, the degree will not increase after adulthood, and it is impossible to reduce the degree.

Professional lens selection skills

 Must be professional to Buy Lenses For Glasses and the product that regular manufacturer produces has production license, cannot buy irregular product to irregular place absolutely, take care of Progressive Eyeglasses lens quality not pass a standard. Lens material selection, currently there are many lenses material. For example, glass lenses have stable refractive index, good wear resistance and stable optical performance. Resin Cheap Progressive Glasses Online lenses are light in weight, wear resistant, light transmittance is high, not easy to crack, but the surface is easy to wear. PC lens: high refractive index, strong, but easy to wear surface. You can choose Progressive Reading Glasses lenses of different materials according to your own needs. Pick the right frame. The weight of the frame must be considered, not too heavy, or the nose is difficult to bear. The picture frame of additional high grade wants firm and deft, after wearing, also feel more comfortable, natural premise also is to need beautiful and easy.

The color scheme of the sun lens

 Yellow Polarized Sunglasses For Sale lens: yellow lens can absorb 100% ultraviolet light and most blue light, after absorption of blue light, the scenery will be more clear, so we can find that when hunting, shooting, wearing yellow Cheap Polarized Sunglasses lens as a filter is very common. The color selection of the lens should be based on the principle that the color of the surrounding environment is not distorted, the edge of the object is clear, and the signal light of different colors can be recognized effectively. The color of lens is better with gray, tan and green, because the Polarized Prescription Sunglasses lens of these colors absorbs better infrared ray and ultraviolet ray. Gray lenses can be evenly absorbed to any color spectrum, and the scenery seen after wearing the lens will only darken without obvious color difference. Tawny lenses filter out a lot of blue light, which improves visual contrast and clarity, especially in polluted or foggy air. Recent studies have found that it is best to avoid blue chips when choosing Women's Prescription Sunglasses because blue lenses do not filter out the blue light in the spectrum of the sun, which is harmful to the eye.

Glass frames made of high-tech materials

 Nickel plated titanium: in order to reduce the cost and make the production more convenient, there are also factories to study the use of titanium metal plated nickel metal. This can then be handled using traditional welding techniques. Pure titanium glasses Frames Online is made of the lightest material in glasses. The hardness is very good, the frame is not easy to deformation, corrosion resistance, rust, does not cause skin allergy, more durable. Titanium Eyeglasses Frames For Men is made of high-tech materials, no rust, no deformation. Its disadvantage is that the material is soft, can not do more delicate glasses, only the line is thicker, in order to ensure the stability and strength of the glasses. In general, PURETITANIUM Clear Frame Glasses are marked on the legs or lenses with 100%TITANIUM or PURETITANIUM. BetaTitanium Glasses Frames are labeled BetaTitanium or β Titanium, which varies slightly from manufacturer to manufacturer.

What is the oxygen permeability of contact lens

 Oxygen permeability: The oxygen permeability of different Progressive Reading Glasses lenses varies greatly. Center thickness <0.04~0.06mm low water content, center thickness 0.06~0.10mm medium water content, and center thickness 0.15~0.20mm high water content Women's Progressive Reading Glasses lens can provide enough oxygen for daily wear. If the cornea is in a hypoxic metabolic state, it will cause complications over time, so avoid wearing contact lenses while sleeping.

About the use and replacement of lenses

 If it is false myopia, through dilation, the eyes after rest and drug treatment, vision can be restored, without Benefits Of Blue Light Glasses. It should be emphasized here that young people should replace Clip On Eyeglasses with dilated optometry. Optometry with Prescription Computer Glasses careless, must be based on regular hospital prescription optometry with Blue Blocker Clip Ons glasses. In addition to subjective optometry, dilated pupil optometry should be adopted. Teenagers' eye muscle regulation function is too strong, so dilated pupil optometry can understand their true refractive state and diopter. The diopter of the matched lens should be consistent with that on the optometry sheet. If the deviation exceeds the national standard, it will accelerate the development of myopia or hyperopia. There are many kinds of lens materials on the market. Resin lens is light and easy to carry, but easy to scratch, especially pay attention to lens maintenance.

About glasses for old people

Features of natural lens and PC lens

 Natural lens material: the High Index Lenses Meaning of this material is made of quartz finely ground, mainly composed of silica (Sio2), 100% Sio2 in pure crystal. Advantages: material hardness is relatively large, not easy to wear; Disadvantages: can not completely absorb the ultraviolet rays of the sun, also can not reduce the transmittance of infrared ray.

PC Transition Lenses material: the material of this lens is solid, mainly composed of polycarbonate, a thermoplastic material. Eyeglasses Transition Lenses can only be formed after heating, so this kind of lens has strong toughness and is not easy to break, so it is called safety lens.

The silver-plated lens is evenly mixed with photosensitive silver halide particles, a small amount of copper oxide and ordinary lens Discount Reading Glasses materials. When silver halide encounters sunlight, a reversible photocolor tautomac reaction will occur. Silver halide can absorb all ultraviolet rays from sunlight, and then the following reaction will occur under the catalysis of ultraviolet rays: AgX2→Ag+X2 (X is the halogen element, including fluorine F, chlorine Cl, bromine Br, iodine I) Since the silver atom particles can absorb visible light, so, the lens turns dark gray. When the Rimless Glasses lens is in a weak light state, the following chemical reaction takes place under the catalysis of copper oxide: Ag+X2→AgX2, so that the lens becomes colorless again.

Test lens transparency and optical uniformity

 Hold the Rimless Eyeglasses lens 30 cm in front of the eye and observe the distant scenery through the lens.
