Semi-rimless glasses are easier to clean and maintain
Semi-rimless glasses usually have only half of the glass frame. We tend to wipe our glasses in one direction, but we all know that the glasses are all wrapped up. So when some small particles appear on our glasses, these things can not be wiped out by the glasses cloth, and it is easy to scratch the lens. This is one of the drawbacks of full-frame glasses.
What is night blindness?
Diminished night vision can also be called night blindness. When you suffer from night blindness, it does not mean that you can't see anything at all at night. This means that you have difficulty driving or seeing things in dark or dim lighting conditions. Night blindness also makes it difficult for the eyes to change from bright light to dim light. This is why night driving in oncoming vehicles can be challenging for some people with night blindness.
Many people have experienced a condition called night blindness, which can make driving at night difficult. Driving glasses at night should help alleviate this situation. However, research shows that night driving glasses are generally ineffective.
If you encounter problems while driving at night, please make sure that all reflective surfaces in your car are clean and free of dirt. You should also see an ophthalmologist determine the cause of the problem. Many causes of night blindness can be easily corrected, making you and others safer during the journey.
Understand the impact of frame selection on the lens
Frame size is an important consideration when using progressive lenses because some progressive lenses work better in frames of different sizes. Since progressive lenses allow you to see at all distances, it's important that the whole range of vision fits within the frame. Therefore, very short lenses and larger lenses are not suitable for progressive lenses.
Contact Lens Materials - HEME Mixed Materials
Using HEMA as the matrix, other monomer components are added to improve the hydrophilicity, oxygen permeability, anti-precipitation, and other functions of the lens.
The Cons of Transition Lenses
However, besides the pros of transition lenses, there are also some negative voices of transition lenses.
The transition lenses are not effective in cars because the windshield blocks the UV rays so that transition lenses won’t darken very well in the car.
Different brands of photochromic glasses have different levels of darkness and different reaction times. So, you may need to ask the doctor to find the brand that works best for you. Transition glasses are affected by colder weather. So it means that it may take a bit longer to react to UV rays in winter. Most transition lenses are not polarized which may result in harsh glares.
So, if you need transition glasses, try Koalaeye Optical, which provides the Koalaeye photochromic glasses. Besides these, Koalaeye Optical also provides other kinds of glasses, such as blue light blocking glasses, polarized sunglasses, progressive sunglasses, and so on.
Do Gaming Glasses Work?
Gaming glasses are similar to computer glasses. They work by countering the hue of the blue light with a yellow tint or amber tint glasses. Clear-lens gamer glasses are available, too. So, gaming glasses can help reduce eye strain and other effects of blue light caused by excessive screen time.
How to Choose Reading Glasses?
In this section, we will show you some tips for choosing reading glasses.
Find the right power. When choosing reading glasses, finding the right power would be the most important thing. All reading glasses will have signs or stickers indicating their power. In most cases, they will range from +1 to +4 diopter, in increments of +0.25. So, when choosing reading glasses, try the lowest power first.
Test-drive the glasses. If you have brought reading material with you, try reading it at a comfortable length. If you hold the material too far out to be able to read it, you should increase the power. Keep testing the differences powers until can read clearly at the distance that’s more comfortable for you.
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.
