A new pair of glasses offers a great opportunity to change your appearance and keep your prescription up to date. Buying glasses online allows you to choose the glasses you like at ease at home. When you order prescription glasses online, the selection and customization process is entirely in your hands, which means you need some important information. Here are some tips to help you choose glasses that fit your face shape, correct your vision, and complement your style when buying prescription eyeglasses online.
Why should I buy glasses online?
When buying glasses online, there are many options for you to choose from. Brick-and-mortar stores and offices have limited space and a limited number of frames to display, making it impossible to offer as many styles and options. Online eyewear retailers don't have these restrictions and can stock up on all the popular styles. When you shop for glasses online, you can find the one you really want from a wide variety of designer glasses frames.
It's convenient and saves money. When you're shopping at an eye doctor's office or a brick-and-mortar store, you must schedule an appointment and make time. Online shopping offers the opposite experience. Buying glasses online gives you plenty of time to make the decisions without leaving your home. In addition, it can also save you money. Online sellers can offer customers the best possible price. You can buy multiple pairs of prescription glasses online at the price of a single pair from an eye doctor so that you can give yourself a different choice of glasses during the week.
What do I need before buying prescription glasses?
1. Your Prescribing Information
To buy prescription eyeglasses online, you will need to get a copy of the prescribing information. For best results, you need to make sure your prescription is up to date. There are different rules for how long eyeglass prescriptions can be used. In general, your prescription may be valid for a year or two. If you have had an eye exam in the past year, you can call your eye doctor to ask for a copy of the information. If it has been more than a year since the last exam, it is best to schedule an appointment to get your new prescription before ordering glasses.
2. Your Pupillary Distance
In addition to your prescribing information, you will also need to know your pupillary distance (PD). This number measures the distance from the center of one pupil to the center of the other pupil. Your PD helps ensure that your frames are centered over your eyes, which aids in fit and proper function, as it ensures the prescription is in the correct position for the lenses.
PD is not always included in your prescribing information. When you pick up your prescription, you may want to ask your optician if PD is listed. If not, it only takes a few minutes for them to measure for you. You can also do this measurement by yourself at home or with the help of your friend. No matter how you get your PD, make sure your measurements are as accurate as possible, especially if you order bifocal or progressive lenses.
3. Your lens thickness preference
Most online eyeglass retailers offer different prescription index options that allow you to adjust the thickness of your lenses. The higher the prescription index, the thinner the lens.
1.56 Index: This is considered a thin lens and is a good idea for anyone with a spherical value between plus or minus 3.75 to 4.50.
1.61 Index: This is considered an ultra-thin lens. This is a good choice if you have a spherical value between plus or minus 4.75 and 6.50 and you want your glasses to feel light.
1.67 Index: This is considered an ultra-thin lens and may be suitable for someone with a spherical value of plus or minus 6.75 to 8.50.
