How to Know If You Need Bifocal Glasses?

As you get older, you will find that is more and more difficult to read or focus on things that are really close up. This is called presbyopia and it is a common eye condition among older people.

How to know if you need bifocal glasses? If you find yourself squinting at the text that once was easy to read or your vision is blurry, you may need to see an eye doctor. In this situation, you may need bifocal glasses to correct your eyes.

If you currently wear glasses but see print more clearly when you remove them, it is a sign that you may need bifocal glasses in the future.

To know if you need bifocal glasses exactly, check your eyes by an optometrist or ophthalmologist.



Who needs computer glasses?

Blue light radiation from computer screens and so on usually only requires a piece of fiberglass to block, usually, we just use the anti-radiation glasses. Office white-collar workers often spend more than 8 hours a day working in front of a computer, and sometimes they spend their entertainment with a computer after going home. After long, the eye often can feel dry, sour bilge, ache, shed tears even, giddy. These are all related to the blue light stimulus emitted by the screen.


First of all, you have to look at your face shape and skin color, and then combine your working environment needs and personal preferences to choose the frame. The corrective glasses should be combined with the test data. Finally, you have full consideration. The single pair has certain characteristics. And the glasses frame has popular fashion characteristics, so the style is always updated.



Why do spectacle lenses fog up?

The fog on the surface of the lens is essentially related to the saturation pressure and water vapor liquefaction. The air is full of water molecules, which are constantly doing irregular movements. When there is no temperature difference, water molecules keep hitting the surface of the lens and will keep bouncing off. The lower the temperature, the slower the speed of movement. Therefore, when water molecules hit the cold lens from the hot air, on the one hand, they move too slowly to fly out in time. On the other hand, because of the relatively low temperature of the lens itself and its vicinity, the water vapor will liquefy. As a result, more and more water will accumulate on the lens and form small droplets, eventually forming a foggy layer. As the lens heats up, the mist evaporates back into the air, and the fog disappears.


Cheap frames can cause skin irritation.

Some cheap frames may look like more expensive frames. But more often than not, they are made of low-level materials that can cause skin irritation over time. Cheap plastic frames can be bleached by ultraviolet light, leaving the surface rough after months of wear and tear. Cheap metal frames often contain nickel alloy, which can cause skin irritation.
