Always abide by up-to-date eyewear prescription –As per norms, the standard validity of an eyewear prescription is one year for minors and two years for adults. And if your eyewear prescription is outdated, then you should visit your local optical shop and go for a new one. It is essential to get your eyes examined, and your optometrist will give you a copy of the eyewear prescription.
Get your pupillary distance measured -Pupillary Distance or PD is the distance between both the pupils, and it is measured in millimetres (mm). The optical center of the lenses gives the real vision, and this particular section of the eyeglasses should remain in front of the pupils. In order to get the right positioning of the eye lenses on the spectacles, the eyeglasses lab requires your Pupillary Distance. The PD is usually between 54 and 68 mm. Given that it is quite a trick to measure the PD on your own, you should ideally get it measured by an experienced optician.
Go for the right size –While buying spectacles, getting the correct positioning of the eyeglasses in front of your eyes should be a primary concern. If you have a pair of spectacles already well fitted then check the measurements that are usually written on the inside arm of your frame. Sometimes, the numbers could be printed on or behind the nose bridge. The numbers represent eye size, bridge size, and temple size.
