How to pick a best frame for oneself
As a eyeglasses manufacturer with years of experience, every time meeting people wearing eyeglasses ,I can`t help looking at them.
Too funny ,once a time I almost followed the guy into a washroom in order to see clearly his eyewear. Hahahaha.
Actually,I noticed many eyeglasses wearers don`t care about some details: even it is twisted so badly or it losing some part or heavily
non-balanced. How could be?Don`t them know it is so harmful for their eyes.Feeling so badly when seeing such things. Not concerning
about the business, just don`t want them to do such carelessly to hurt themselves.
Eyes is so important for us.
So we are going to talk to you about those frames today.
Hope it could be a little helpful for the wearers who read this article.
In this times that everyone like to be good-looking ,with a nice and beautiful design eyeglasses is necessary. But, more importantly,
it is to choose suitable eyeglasses for you as your partner because he will company you all the time, especially for those who wearing
prescription glasses.
First,what is a good spectacle frame?
The spectacle frame first exists as a positioning device for lenses, then is beauty.
Therefore, it must have two basic requirements: straight and not easy to shit.
1.What details does "straight" include?
First the pupil and the optical center of the lens coincide.
Second Horizontal direction is not skewed.
Third Obliquity proper
Fourth frame must be on the same surface.
Bad example as following:
Pupil height in above picture is too low, after wearing, frame will be skewed.
1. What is the Panascopic tilt?
If it is too big which makes the bottom of glasses too close to the cheek.
If it is too small which makes the bottom of glasses far fram the cheek
2. What is good base?
But,bad base as following which are not on a curved surface.
3. What details does "no easy to shit" include?
It is basiclly symmetric on both sides.
Second:Several important dimensions affecting comfort.
1. Make sure that the opening size of temple is proper.
If smaller,it will make wearers feel tight and after while, it will leave a trace on this side of face.
If bigger, the frames will be moved so easily and always need to push it back.
2. Take care of the lenth of temple
If too longer, the frame will be easily slide which will make the wearers feel so uncomfortable
If too shorter, which will increase the panascopic tilt
3. the fitting degree of nose pad:
the larger the area of the nose pad, the better the comfort. Conversely, the worse. We should also pay attention to the distance
between the nose and eyelashes, especially the ladies, so as to prevent the eyelashes from touching the inner surfaces of the lenses.
4. Pupil height position:
It is necessary to consider whether the pupil is too low under normal wear after the lens is loaded, so that the frame has no need to
be pushed frequently.
Third:different prescription of optometry limits the material and structure of spectacle frame
1.rimless frame with astigmatism is not recommended because once the screw is loose, the astigmatism axis will change.
2. if the degree between the left and right eyes is large. The improper selection of spectacle frames is easy to slowly skew during wear.
It is recommended to choose a optical frame with material and structure that has large adjustable range.(Metal frame will be better)
3.If the prescription joint degree is higher than 600 degrees, the front end has a larger weight, than you need carefully select the temple
material with better elasticity, such as TR, plastic steel (PEI), stainless steel and beta titanium. Acetate will be better.
4. If the prescription degree is higher (more than 600 degrees), it’s better not to choose frame with spring hinge,for over-clamping one
affects the comfort, the loose one makes the frame easy to slide frequently.
5.If the face is asymmetrical and the ears are high or low, it is not recommended to use wide temple(unable to adjust the inclination),
flexible temple material (TR, plastic steel PEI, stainless steel, beta titanium, etc.) and integrated nose pad. Metal will be better.
5. If the bridge of the nose is slightly asymmetrical and the nosewing is asymmetrical, it is not recommended to use an integral nose pad
or a one with a small adjustable range.
The frames without nosepad will better.
Forth, The glasses used for special occasion
1. For people who like watching movies. Whether using 3D clips or cinema 3D glasses, the size will be relatively small, the choice of lens frame
size needs to consider the coverage.
2. In the larger environment of sand or dust. Do not choose structures and styles that are not easy to clean, such as hollowing out, crystal inlay,
scaling-prone structure, painting wear-prone surface, etc.
3, For sweaty people. It is not recommended to choose the frame with spray paint, and non IP plating (especially gold plated)
Our eyes is so important to us, we sincerely hope that you could protect your eye with the proper eyewear style, so let you are in good mood
every day.
