How to buy anti-blue light products?
In order to further standardize anti-blue light products and make all kinds of products effectively protect eye health, relevant standards have been formulated. Based on the different effects of blue light in different bands on the human body, the transmittance of blue light in each band is required in the standards.
For example, in the band range of 415-445 nm, the transmission ratio of light is less than or equal to 80%, and more than 445 nm, it is greater than 80%.
Which Glasses for Computer Are the Best?
There is no such a thing that one type of computer glasses can fit all or is the best for everybody. When selecting glasses for screen protection, the visual ability, personal preferences, the type of work, the distance between the computer user’s eye and the monitor, and other factors should also be considered.
What Are Gaming Glasses?
Gaming glasses are designed for people who play video games on computers or gaming systems. Many gamers and e-sports competitors spend long periods in dark room and the blue light from the screen can affect their eyes. However, if they wear gaming glasses when playing computer games, they can protect their eyes because they provide anti-reflective coating, magnification, and blue light protection.
Gaming glasses with anti-reflective coating helps to reduce glare, which is light that reflects back into your eyes from a digital device. Reducing the amount of glare can help to make eye focusing easier, improve color contrast and potentially increase your reaction time.
Many gaming glasses add a small magnification power to their lenses, which can reduce squinting and eye strain.
The gaming glasses can also help to block blue light and improve your body’s circadian rhythm and improve your sleep quality.
So, you can find that gaming glasses are beneficial to your eyes. However, do gaming glasses work?
What Are Progressive Lenses?
Progressive lenses have grown in popularity and are one of the most common solutions to treat vision loss that occurs with age or presbyopia. This eye condition occurs when the eye loses some of its flexibility and ability to adjust to clear seeing objects at different distances. Presbyopia often occurs among adults who are over age 40 and is very easy to correct with a proper and prompt diagnosis.
Progressive lenses are often used to correct this eye condition. Progressive lenses are a modern alternative to bifocal glasses, which provides two prescriptions in a single set of glasses. Bifocal glasses are a better solution than carrying around multiple pairs of glasses. Progressive lenses were developed to resolve some of those common issues and to provide better aesthetics. Progressive lenses provide a smooth transition and can accommodate up to three prescriptions and are a replacement for both bifocals and trifocals.
The too apparent frame will be distracting. Rimless or light-framed glasses are the least visible, avoiding stealing the wearer's thunder, and look more mature, which is why many business leaders wear rimless glasses. For those with low levels of self-deprecation or obvious shortcomings, wearing glasses may be a plus.
How to drive at night with glasses?
If you need to wear glasses while driving, you'll need special glasses when driving at night, because common lenses reflect oncoming lights, which produces a faint glare. This will reduce your visibility. It's OK to wear contact lenses while driving. As you get older, your eyes become more sensitive to glare. Ordinary sunglasses or goggles are only suitable for wearing during the day, driving at night will seriously affect the vision (national standards stipulate that light transmittance of night driving glasses must be greater than75%). Although the all-weather driving glasses can weaken the strong lights, the vision darkens and affects road safety which does not meet the national standards for driving glasses at night. You should choose functional driving glasses that can block strong light, glare and increase the field of vision. This can effectively reduce the glare of the car lights but can filter out the extra harmful light. When worn at night, it can soften the strong lights and make the vision clearer. In this way, the safety of drivers is ensured, the fatigue of eyes is alleviated, and the radiation damage of harmful lights to glasses is prevented.
How can you tell if blue light glasses work?
It can be identified in the light. Ordinary lenses have a yellowish feeling under the reflection of light, while the anti-blue lens film color has blue on the yellow-green film, which is the cause of reflecting blue light out. Check the instruction manual to verify that the lenses contain radiation-resistant materials. When wearing, you can look at the electronic screen far away, and check if there is a sense of irritation to the eyes. The biggest difference between the regular lens and the anti-blue lens is the coating layer. If you look carefully, you can see that the anti-blue lens layer is very clear. Put the anti-blue light glasses on the fully open phone screen and observe if the covered area is blue. If it is, the prevention effect is good. This is because the blue light emitted by the phone is reflected on the phone screen by the lens.
