How Do Prism Glasses Work?
After learning what prism glasses are, you should know how prism glasses work. So, in this section, we will show how prism glasses work.
People with binocular are struggling with seeing two images instead of a single image. The light they see falls in different places on their retinas, which causes distortion and doubling of what they are seeing.
Meanwhile, prism glasses are mostly used to deal with double vision, making it easier to maintain binocular vision, which is the ability to maintain focus on an object with both eyes. With the prism glasses, the light bent before it hits the retina. It is redirected so it falls correctly and the brain can interpret the message as getting in the usual manner, resulting in a single clear picture of seeing.
Do blue light glasses really protect your eyes?
Scientists at the University of Kansas in the United States summarized the results of studies around the world in the past 30 years and pointed out that there is not enough evidence in human trials to prove that blue light is related to macular degeneration, and there is no test showing that blocking blue light glasses are related to macular degeneration. Moreover, experts from the University of S?o Paulo in Brazil have observed after five years that patients who use anti-blue light intraocular lenses after cataract surgery have no difference in the incidence of macular disease compared with those who use ordinary intraocular lenses.

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.
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.

Titanium is currently too expensive to refine.
It is highly demanding in buckling, stamping, cutting, and welding. The extraction of titanium, like that of aluminum before the 19th century, was quite costly and produced in limited quantities, so it was used only in extremely important fields, such as aerospace, electronics, precision instrument manufacturing, and so on.
What Are Glasses Without Prescription?
Nowadays, some people wear glasses not only just for correcting their vision, but also for fashion. However, for those people who do not have any eye conditions such as nearsightedness, farsightedness or astigmatism, they can wear glasses without prescription.
Glasses without prescription, also called non-prescription glasses or clear lens glasses, work as a fashion statement to add style to your wardrobe. They also may serve a purpose if they have blue light blocking lenses.
Throughout the years, many people choose to wear glasses without prescription to improve their look. This trendy accessory is a reality available in a range of designs, colors and materials that can add just the right touch to your outfit.
It is important to note non-prescription glasses have zero corrective power whatsoever, while non-prescription reading glasses offer some level of magnification, enlarging what you see up-close.
