What Strength Reading Glasses Do I Need?

What strength reading glasses do I need? You can choose the reading glasses strengths by age or you can also perform a reading glasses test. If you are aging from 40 to 44, the +0.75 to +1.00 dioptre power is recommended. If you are aging from 45 to 49, the +1.00 to +1.50 dioptre is recommended. Age from 50-54, recommended power is +1.5 to +2.00 dioptre. Age from 55-59, recommended power is from +1.50 to +2.25 dioptre. Age from 61-65, recommended power is from +2.25 to +2.50 dioptre.

If you find two different strengths of reading glasses are available, choose the lower power because too strong strength can cause discomfort compared to weaker powered glasses and can even lead to nausea and dizziness.

So, if you need a pair of reading glasses, try Koalaeye Optical, which is an online glasses store. It provides all kinds of eyeglasses, sunglasses and frames. You can choose the satisfied one from here.


Do you need to wear glasses to drive?

In the evening, lights from street lamps, buildings, and other vehicles create a lot of reflection on the windshield, making it hard to see. It's even worse when it rains. But if your glasses have an anti-reflective coating, they can reduce the glare and reflections, allowing you to see more clearly while driving at night.



Does glasses make your eyesight worse?

If you wear suitable glasses, pay attention to eye hygiene, and your myopia can be stabilized to a certain level. If you do not pay attention to eye hygiene, or if the glasses for myopia are not suitable, the degree of myopia will increase. If you wear myopia glasses but don't wear them for a while, or usually put them in your pocket and wear them when you look at distant objects, it will also deepen the degree of myopia. Therefore, the deepening of the power is not caused by glasses but is caused by not wearing suitable glasses frequently.


Benefits of Progressive Lenses

The lens looks like a single vision lens, with no dividing line between degrees. Not only is it beautiful in appearance, but more importantly, it protects the privacy of the wearer's age (for the wearer of reading glasses). There is no need to worry about showing the secret of the wearer's age by wearing the glasses. Because the degree is gradual, the replacement of the adjustment effect is increased step by step according to the shortening of the close distance. There is no adjustment fluctuation, which is not easy to cause visual fatigue. Clear vision can be achieved at all distances in the visual scope.



Bertoni polarized glasses

Bertoni polarized night vision driving glasses are made of strong, flexible, durable, and ultralight polycarbonate. Yellow polarization increases contrast, improves visual acuity, and filters out blue light. They are great for drivers, cyclists, and winter sports enthusiasts. The driving glasses with polarized yellow lenses block glare from headlights, reduce night driving glare, improve night vision, and improve color clarity and visual clarity. They are ideal for driving in low-light conditions. Most sports sunglasses glasses frames and goggles are made of polycarbonate because of their strong, thermoplastic, lightweight, and impact resistance features.


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%.



Zeiss lenses

Carl Zeiss AG is a German company that manufactures optical systems, industrial measuring instruments, and medical equipment. The name of the company comes from one of its founders, German optician Carl Zeiss (1816-1888). It was established in Jena in 1846 by Carl Zeiss, Ernst Abbe and Otto Schott.

Zeiss resin lens guarantees up to 99.4% of the lens light transmittance. The naked eye can no longer feel whether the lens is worn or not. So far, only Zeiss, the leading optical industry, can bring such extraordinary extreme effects. Moreover, in order to ensure the good imaging quality of the lens and make the lens longer life, Zeiss also adopted a new coating design, imported from Korea. The unique professional technology is combined with nanotechnology so that they manufacture the good quality of the top lens.
