Non-prescription glasses – advantages ?

For many people, glasses are just a styling accessory. When you choose them, you have to think first and foremost about health, not fashion. How do I choose sunglasses? The most important thing when choosing glasses is to adapt them to the individual needs of the eye and the way of life. This rule also applies to corrective and sunglasses. Do not buy cheap glasses at markets, as they can cause permanent damage to your eyesight. The low price indicates that these are not e. g. anti-reflective glasses or other protective coatings.

Non-corrective glasses are primarily a solution for people who work in front of a computer, spend a lot of time in front of a TV set or other device that has a screen such as a phone, tablet, laptop. They are also ideal for children and adolescents of school age.  More and more schools are using monitor boards and projectors, which are tiring or even eye-catching. To sum up, the lenses used in non-corrective glasses are not designed to correct vision, but only to protect it by using eye protection coatings, such as anti-reflection coatings.

Is it worthwhile to invest in kindergarten glasses - opticians opinions

According to opticians, the most common cause of visual impairment are various types of monitors. The light they emit can cause:
  • tiredness,
  • problems with concentrating,
  • headaches,
  • pinching, burning and reddening of the eyes.

Long hours of work at the computer and watching TV or constant staring at the screen of the phone irritates the eyes with light reflections. The solution to this problem is the anti-reflective non-corrective glasses. Why would I do that? The anti-reflective coating minimises the reflection of light from both the outer and inner surfaces of the lens. This eliminates the feeling of fatigue when working with the monitor. In addition, it provides better contrast and sharpness. Anti-reflection coating does not distort the real image. It only minimises the penetration of light into the eye, including water that is split by particles of water circulating in the atmosphere.
