Optometric data
Accurate degree: Go to a professional eye institution or optician for optometry to obtain accurate myopia, farsightedness, astigmatism degree and axial position data. This is the basis for the selection of optical glasses, only the degree of accuracy, in order to effectively correct vision, reduce the burden on the eyes.
Consider pupil distance: Pupil distance is the distance between the pupil centers of the two eyes. The appropriate pupil distance can make the optical center of the lens correspond to the pupil of the eye, ensure clear and comfortable vision, and reduce eye fatigue and discomfort.
Lens material
Glass lenses: With high refractive index, good optical properties and wear resistance, can provide a clear visual effect. But the disadvantage is that the weight is heavy, easy to break, and the safety is relatively low.
Resin lens: light weight, strong impact resistance, not easy to break, high safety. At the same time, it has good optical properties and can effectively block ultraviolet rays. However, its wear resistance is poor relative to glass lenses, and it is prone to scratches.
PC lens: also known as polycarbonate lens, is a new type of lens material. Its strong impact resistance, light weight, but also has good anti-ultraviolet performance, suitable for sports enthusiasts or children to wear. However, the refractive index of PC lenses is relatively low, and the lenses may be thicker and more expensive.
Lens function
Single-light lens: suitable for people with simple nearsightedness, farsightedness or astigmatism, it can only correct a vision problem and provide a single diopter.
Progressive multi-focus lens: there are multiple different diopter areas on the same lens, which can meet the vision needs of far, middle and near different distances at the same time, suitable for middle-aged and elderly people or people with presbyopia.
Anti-blue lens: can effectively block the harmful blue light emitted by electronic devices, reduce the damage of blue light to the eyes, suitable for people who use electronic devices for a long time.
Frame material
Metal frame: common titanium alloy, nickel alloy and so on. Titanium alloy frame light weight, corrosion resistance, high strength, comfortable to wear, but the price is relatively high. The price of nickel alloy frames is relatively close to the people, and the styles are diverse, but there may be allergy problems, and people with sensitive skin need to choose carefully.
Plastic frames: including sheet and TR90 materials. The plate frame is rich in color, fashionable in style, has certain elasticity and flexibility, and is not easy to deform. The TR90 frame is light in weight, high in strength and good in fatigue resistance, and is suitable for all face shapes and wearing needs.
Natural material frame: such as wood, horn and other materials of the frame, with a unique texture and style, giving people a natural, retro feeling. However, these frames are relatively expensive and require careful maintenance.
Frame style
Face shape adaptation: Round face is suitable for square or rectangular frames, which can increase the three-dimensional sense of the face; Square face can choose round or oval frame, soft face line; Heart-shaped faces are suitable for wide edges or decorative frames to balance the face proportion; Diamond faces are suitable for round or polygon frames to modify the contours of the face.
The right size: The size of the frame should match the size of the face. The length of the mirror leg should be appropriate, too short will compress the ear, and too long will easily slip. The width of the frame should be slightly wider than the width of the face, to avoid the edge of the lens beyond the face, affecting the beauty and vision.
Personal needs and lifestyle
Daily use scenario: If you often do outdoor activities, you can choose lenses with UV protection and lightweight, durable frames. If you spend a lot of time in the office, anti-blue lenses and comfortable frames are more appropriate.
Sports needs: People who like sports can choose sports special optical glasses, such as frames and PC lenses with anti-slip and anti-impact functions, to ensure safety and comfort during sports.
Beauty and style: Choose the right style of glasses according to your personal preferences and wearing style. If you like a simple style, you can choose rimless or thin frame glasses; Those who pursue fashion trends can try some personal and unique frame designs.
