How to do with it?
Wash your glasses once a week to avoid future accumulation. Remove the green goo with a soft cloth, a cotton swab, some mild dishwashing liquid, alcohol, and a soft-bristled toothbrush. Ultrasonic cleaning machines can remove dirt and green mud because vibration can do with micro-mud. This device is available in most optician stores, so you can have your glasses cleaned there. Just like anything we use, glasses need to be replaced. It is recommended that you replace the nasal pad with a new one every 6 months to keep it sanitary.
What Are High Index Lenses?
High index lenses are eyeglasses lenses that are designed to be thinner and lighter than regular lenses. High-index lenses have a high refractive index than their conventional counterparts. High index lenses are recommended for people who have significantly high refractive errors and strong prescriptions for nearsightedness, farsightedness or astigmatism.
High index lenses are thinner, lighter and more appealing than standard lenses, but they come in several different indexes such as 1.67 high index lenses and 1.74 high index lenses. In this post, we will focus on the 1.67 high index lenses and 1.74 high index lenses.
How to Choose Reading Glasses?
Choose big frames the first time. When choosing reading glasses, you can choose the big frames for the first time. You may need larger glasses frames or lenses to really get the sweet spot of where the prescription is.
And if you have never worn glasses for eye conditions such as nearsightedness, farsightedness or astigmatism, it is likely you will be able to see well with non-prescription reading glasses. So, you can buy these non-prescription reading glasses.
Large frame glasses
This year, glasses with large frames are popular, or glasses with wide edges are good-looking. The design inspiration of many series comes from the classic design. The rectangular frame shines brilliantly, but the angular line is softer. Many frames are made of synthetic fiber materials with excellent sculpture effect and wide application range, which has become mainstream.
What is a progressive lens?
A progressive lens is a lens whose upper sides are used to see far, and the lower side is used to see near. The distance from the fixed distance power above the lens to the near power fixed below the lens does not change suddenly, but a gradual transition between the two through the gradual change in refractive power.
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. However, is progressive lens good for eyes?
Sometimes they need to be adjusted by professionals.
Some connecting parts of glasses will be loose, but some people do not care about them and make casual changes. In reality, the change of the lens frame is very technical. The distance between the lens and the glasses will affect the effective strength of the lens, so the adjusted glasses need to be 12 to 14 mm away from the eye. The optical center of the lens should be aligned with the pupil position, and the nose pad, the temples should be consistent with the contact part of the bridge of the nose and the ear, without pressure and pain. Therefore, the lens frame must be adjusted by a professional optician. Especially some special lenses (progressive multi-focus glasses) need to be repaired regularly.
