The lens material
Lens material affects the effect of protecting our eyes, so we should choose the kind of driving glasses made of polarized lens, which can effectively reduce the dazzling lights, and can filter out the redundant lights. When used at night, the powerful light is softened and the vision is clearer, thus ensuring the safety of drivers and relieving eye fatigue. If you can, let the seller dim the light when you buy, feel the softness and clarity of the light after wearing the product.
Glasses are no longer ordinary daily necessities. A pair of glasses not only can assist eyesight, but also enhance or even change your temperament. In addition to the material, color, and shape, when choosing glasses, the most important thing is to match your face. Some frames are really good-looking, but they will be scary if they don’t match the shape of your face. Today we will talk about how to choose glasses according to your face shape.
Progressive Lens
Standard progressive lenses are multifocal lenses with three observation areas, farsightedness, intermediate vision, and nearsightedness. Unlike bifocals, there are no visible lines between each viewing area. They have a seamless, invisible design, where the optical power changes 'gradually' throughout the lens. Many people confuse 'bifocal' or 'trifocal' with 'progressive' but remember that bifocals and trifocals have visible lines in the lens, while progressive lenses do not. Because progressive lenses have no lines in the lens, they are more popular multifocal lenses than bifocal lenses.
The main observation area of the progressive lens is a far distance, the smaller area at the bottom of the lens is used for myopia, and the middle area in the middle is smaller. Standard progressive glasses are very suitable for general purpose glasses, focusing on hyperopia activities (such as driving and walking) and sufficient area in the lenses for nearsighted activities (such as reading and computer use). The left and right sides or 'convex corners' of the lens are deliberately blurred to achieve an invisible design. The clearest line of sight in the gradual process is from the center to the top of the lens.
Choose lenses with good optical clarity.
If you're wearing low-cost glasses, the quality of the polycarbonate lenses may not be as good as expected. If you wear a pair of safety glasses and the lenses look cloudy or have tiny distortions, it's a sign of poor optical quality. Lenses with excellent optical quality are free from aberrations and imperfections, and they allow to be seen using as close to natural vision as possible.
How To Use Contact Lens Correctly?
Check your eyes for abnormal cases. Do your eyes sting or dry? If so, it is recommended not to wear contact lenses for the time being. Look in the mirror to see both eyes carefully, if it is red and swollen or if is both eyes full of bloodshot? If you do, you can no longer wear contact lenses, and you can go to a professional store for inspection. After putting on the contact lenses, block the left and right eyes respectively to see if the vision of one eye is clear. If the eye vision has decreased or blurred, check if the lens is dirty. If the lens is still the same, you should go to a professional store to find out the reason.
