At the same time, in the process of wearing contact lenses, the lens may be polluted, damaged, and have other changes. This is to check regularly to prevent damage to the eyes.

Points to Note When Buying Saddle Bridge Glasses

Ask yourself the following questions: Is it worth buying saddle bridge glasses? What are the benefits of buying saddle bridge glasses? Which saddle bridge glasses are better on the market at present? Where can you find information about saddle bridge frames? It includes buying guides, rating sites, word-of-mouth recommendations, online forums, and product reviews for saddle bridge frames. These studies are important to ensure that you get the best saddle-bridge frames possible. Make sure you only use trustworthy websites and sources.



The shape of the lens is also important.

Aviator and cat-eye glasses should be avoided, as both will cut off the base of the prescription, resulting in poor reading vision. Instead, they should opt for shorter frames with rounded edges, such as bull horn frames, vintage wingtips, round frames, and oval frames.


The characteristics of suppleness, lightweight and non-deformation

Pure titanium glasses have the characteristics of ultra-high flexibility, ultra-light, and not easily deformed. Pure titanium spectacle frames get rid of the shortcomings of ordinary spectacle frames that are stiff, heavy, and easily deformed. Medically implanted high-grade plate materials, combined with the color electroplating process, highlight youthful vitality and three-dimensional sense, making our facial features more refined. The nose pads are stable, not slack, and highly conformable, which avoids the embarrassing moment of the glasses frame falling down. And pure titanium glasses can make you look stable and reliable, and people can't help giving you more trust.



Why are titanium glasses expensive?

One reason is that the current titanium raw material cost is too high. The other reason is that the production of titanium frames is very complex. The production of titanium glasses requires special processing equipment, special welding technology, and electroplating technology, and many difficult and different processes, so it has a high production cost.

With the emergence of new titanium glasses production equipment and the improvement of production and processing technology in the industry, the price of titanium glasses will become lower and be available to a wider range of people.


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.



Contact Lens Material - PHEMA material
