Advice of buying your prescription eyeglasses online
Purchasing prescription glasses online can be a great way to find the perfect pair of frames and lenses for your unique vision needs. However, it is important to keep in mind that there are some key considerations when shopping for eyeglasses online. Knowing the basics of reading your eyeglass prescription and understanding different types of lenses is essential to ensuring you get the right pair of glasses.
When you receive an eyeglass prescription, it will typically include four frame measurements: sphere (SPH), cylinder (CYL), axis (AXS) and pupillary distance (PD). The first three measurements indicate the power, or strength, of the lens and include the amount of correction required for near-sightedness and far-sightedness. The PD measurement indicates the distance between the centers of your eyes. It is important to provide this information accurately when ordering your prescription glasses online as it affects how the lenses fit in the frames.
In addition to these measurements, you should also consider the type of lenses you need. Single vision lenses are used for basic vision correction and are ideal for those who only require one prescription for both distance and near vision. Progressive lenses allow for multiple prescriptions for different viewing distances and are best for those with presbyopia, or age-related vision loss. Bifocal lenses are similar, but have two sections in each lens that offer separate prescriptions for near and far vision. Photochromatic lenses contain molecules that lighten and darken the lenses depending on the amount of light they are exposed to and can be useful for those who often move from inside to outside.
Once you have determined the type of lenses you need, the next step is to compare frames and lenses offered by different online sellers. Make sure to look at the frame size, shape and material to ensure the frames will fit comfortably and suit your style. Also, compare the features and cost of different lenses to make sure you are getting the most value for your money. Lastly, read reviews of the vendors and check out their return policies to make sure you are dealing with a reliable company.
By following these steps, you can purchase prescription glasses online with confidence, knowing that you are getting the right lenses and frames that meet your unique vision needs. With a little research and comparison shopping, you can find the perfect pair of prescription glasses that are comfortable and stylish.
