How to Keep Glasses from Slipping
Stick-on Nose Pads
Nose pads would be a good choice to prevent glasses to slide down your nose. Hence, you can stick a pair of rubber pieces in the nose pads of your glasses or you can choose a pair of glasses with rubberized nose pads. If you want to try a pair of nose pads glasses, the Koalaeye Optical may be a good choice. The rubber nose pads will make you feel steadier and better and the additional resistance on the nose pad will surely provide more support. So, if your glasses often slip down from your nose, try this way.
To keep glasses from slipping, you can try wax coating which is a smart move. Use the wax on your nose pad area along with the temple where the glasses come into contact with the skin. In general, it works fine and it is nearly invisible.
Temple Ear Hook
The temple ear hook is a good way to keep glasses from slipping. It can provide mechanical support behind the ear and you will feel the support from the back of your ears. But the drawback of the temple ear hook is that it is quite visible. When you take off the lenses, you need to lift the temple higher so that the ear hook could clear the ear’s crest. Besides, the cheaper one might cause some discomfort to the back of your ears because of the pressure.
Rubber Bands and Hair Ties
To keep glasses from slipping, you can also try hair ties and rubber bands. You can tie one around the temple tip behind your ear so that it can provide both slight mechanical support and friction forbidding your glasses from moving around. What’s more, this is a low-cost method.
What is the bifocal lens?
Bifocal reading glasses are characterized by distance vision correction in the upper part of the lens and near vision correction at the bottom. If you need help with both, that's great. This lens is designed to facilitate the working of reading glasses and standard prescription glasses, all in one frame. Glasses are recommended when you are diagnosed with presbyopia, and bifocals are usually the first choice. But for intermediate vision, bifocals are difficult because they're not close enough for the reading part of the lens, and they're not far enough away for the distance part of the lens. Bifocal sunglasses have no magnification at the top, and the reading ability is at the bottom of the lens. Bifocal reading glasses can be found anywhere reading glasses are sold, but they can be harder to find than full magnifying lenses.
What color lenses are good for driving?
The optometrist reminded us that it is not advisable to choose pink, purple, light blue, and other colors with obvious decoration effects for driving sunglasses. These colored glasses basically cannot protect the eyes. In addition, they may change the color and cause chromatic aberration. Generally speaking, you should wear brown and gray glasses when driving. The brown lens can filter out a lot of blue light, which can effectively improve visual contrast and clarity. The gray lens can absorb any color spectrum in a balanced manner and will not produce obvious chromatic aberration after wearing.
Nowadays, the colors of lenses for sunglasses on the market are dazzling. Many people only consider whether they look good when choosing colors, and do not pay attention to the impact of lens colors on vision. When choosing sunglasses, we should not only pay attention to their decoration but also pay attention to their protective function for the eyes. We should avoid using blue lenses when driving because it will make us unable to distinguish the color of the traffic signal lights.
Who are suitable for progressive lenses?
A progressive piece is suitable for most old people to wear. The proper person is the one who has the visual needs of the long, medium and short distance cares about beauty, and is willing to accept new things. In order to avoid binocular vertical prism differences, for the wearer whose equivalent spherical lens with anisometropia is more than 2D, especially if the difference in refractive power of the vertical meridian is more than 2D, it should be checked with caution. Opticians whose vision needs do not match the progressive lens design, like dentists, often experience blurred vision when working with the far side of the lens to look closer.
How to handle rusty spectacle frame?
Skin allergies are after the rust of the spectacle frame, so we have to solve the problem of rust of the spectacle frame by physical isolation. Apply a layer of transparent nail polish on the metal surface, or add an anti-allergic sleeve on the temple of the eyeglasses so as to separate the skin from the metal by resin. Both of these methods isolate the skin from the spectacle frame, effectively preventing corrosion of the spectacle frame caused by sweat and grease.
The glasses slid up your nose.
Although glasses often slide up your nose and pushing them up can be annoying, it's easy to pull them tight. If your nose frame is metal, use your thumb to shrink the nose pad until the frame no longer slides. If you have plastic frames, soak the arm in warm water for 30-60 seconds, then apply slight downward pressure to the end of the arm. This will make it fit more behind the ears, which will tighten the overall fit and prevent slippage. If tightening the frame doesn't work, try using eyeglass wax to stop it from slipping.
What Are Progressive Lenses?
Traditional eyeglasses are usually single vision lenses with one prescription. Progressive lenses are multiple with three prescriptions in a pair of eyeglasses. Progressive lenses let you see comfortably at different distances, allowing you to see close, near, and far without changing your glasses. There are other kinds of multifocal lenses like bifocals and trifocals, but progressive lenses differ because of their smooth transition between prescriptions.
Bifocals and trifocals work similarly to progressive lenses and feature either two or three prescriptions in a pair of glasses. These lenses have definitive lines separating the prescriptions. However, progressive lenses don’t use these lines and allow you to easily transition between prescriptions.
Hence, in the following section, we will show you 6 different types of progressive lenses.
