Considerations for Purchasing Prescription Eyeglasses Online:
Here are some factors that you will need to consider before ordering prescription eyeglasses frames online:
1. Prescription Information:
It is always recommended to secure your prescription details so that it’s convenient for you to enter your information online while ordering eyeglasses. You just have to make sure that your prescription details are up-to-date. According to the Federal Trade Commission, eye doctors are not allowed to charge you extra for your prescription. However, there are different rules in different states. But it’s recommended to upgrade your prescription every one or two years. Moreover, make sure your prescription includes:
– Right and left sphere
– Left and right Cylinder
– Right and Left Axis
– Prism Correction
– ADD power number
2. The Pupillary distance:
It is also important to know your pupillary distance that is the distance between the centres of your pupils. This helps to ensure that your eyeglass lenses are centred over both eyes correctly.
3. Your Preference for Lens Thickness:
Many people are not aware of the lens thickness and they do not even bother to consider it when it comes to buying eyeglasses frames. It is important to know the standard index numbers that are usually between 150 and 156. The thickness may vary according to the sphere value e.g. 1.56 index is considered to be a thin lens and can be perfect for sphere value between 3.75 and 4.50 (positive or negative).
4. Determine Frame Size According to Your Face:
Another important factor to consider is the frame size that will suit your face. The size does not only include the overall size of the frames but also the lens measurement. It is easy to determine the size of the frames if you know the lens width. The Size of the frames also includes bridge width, temple length, and frame width. All these measurements are mentioned on the eyeglasses sites to choose a suitable frame for your face.
5. Choose a style according to Your Face Shape:
This is another one of the most important factors that you must consider before choosing eyeglasses online. For example, if your face is oval which means a longer forehead as compared to the other shapes. For oval shapes, it is best to choose cat-eye, square, rectangular, or round glasses frames. For a square face, as the jaw and forehead are wide and defined, you can go for round, oval, or browline eyeglasses styles to soften the features.
