The Best Guide for You Before Buying a Pair of Glasses

Are you going to buy a pair of glasses? Buying glasses is basically a simple thing. You will be tested to select the frame and lens of the glasses that best suits you. Here are some useful tips to make sure which sunglasses are suitable for you:

Choose the right lens

You have two basic options, single-vision lenses or multi-focal lenses. Single-vision corrects remote vision while multi-focal corrects remote and short-range vision. As aging, most of us can no longer rely on single-vision lenses that have only one focal point, generally in the distance. Most people will eventually need multi-focal lenses. Two types of traditional multi-focal lenses are bifocals, which have two different corrections, one at the top for long distances and the other at the bottom for reading; and trifocals, which have three different corrections, one at the top for long distances, one in the middle for medium-range vision, and the last one, at the bottom for reading.

In recent years, bifocal and trifocal have been defeated by progressive lenses, which work in the same way but offer a smooth transition and do not provide a dividing line. The type of lens that works best for you depends on your visual needs and your level of personal comfort. Be sure to try different types of lenses before you buy. If you are accustomed to using bifocal lenses, you may have difficulty adjusting to progressive lenses.

Lens Size

Stylish glasses are often selected because their shape not because of their function. This often makes people choose lenses that are too small. The form of glasses that is popular today is small rectangle. For single-vision lenses, small lens sizes may be sufficient, but if you need bifocal, trifocal, progressive, or special reading aid, you need an eyeglasses lenses replacement.

Consider Photochromic Lenses

If you expect to get one lens prescription for glasses, Photochromic lenses may be the best choice. Recent technological breakthroughs have made the lens overcome the previous shortcomings, such as the slowness to adjust to indoor and outdoor light.

Avoid designer labels

Keep using generic frames. Frames with designer labels are sold more expensive than others and are generally no better than unnamed brands. You also need to say no for the addition of anti-reflection layer as this layer does not reduce the glare. This is only useful as an additional sale for glasses sellers. Do not get caught up in situations where you’re disappointed to be affected by famous brands.

Consider polarized lenses

Polarization really reduces glare. Here’s how it works. Most of the glare comes from horizontal surfaces such as water or roads. The polarized lens remains at an angle that only allows vertical polarized light through the lens.

Do not underestimate the cheap reading glasses.

Cheap reading glasses sometimes get a bad reputation, but reading glasses are actually a good choice for improving presbyopia, age-related conditions that gradually make a person more difficult to read.
