Almost a fourth of the world’s population has to wear prescription glasses to correct their vision. This means that a lot of people are buying spectacles. When the time comes for you to choose yours, you need to pay special attention to the lenses as they are the most important part of your glasses. Sadly, many of us do not pay enough attention to choosing the best lenses. Here is a brief explanation about the importance of choosing the right glasses.
Which kind of glasses do you need?
The first thing you need to do is decide whether you need single vision glasses or multi-vision glasses. Most of us however will not need to choose anything other than single vision prescription glasses. However, if you have both farsightedness and nearsightedness issues, then you may be better served wearing multi-vision glasses. Progressive glasses are a good option because they have different optical strengths and so you can correct both your near and farsightedness without needing to change your glasses.
Choose lenses carefully
Second, you need to decide which kind of lenses are best for your vision. We all have unique eyes and our eye problems also differ from person to person. There are also different kinds of lenses to choose from including high index, polycarbonate, and photochromic lenses. If you can afford them, then you should opt for high index lenses because these are able to refract light better than your regular plastic lenses. They are also very thin and light and so are a good option.
You may also want to opt for polycarbonate lenses because these are impact-resistant and they provide good protection to your eyes from the dangerous UV rays of the sun. these lenses are also lighter and thinner than regular plastic lenses and they are especially useful for correcting your child’s vision or that of an aged person.
Photochromic lenses are designed to protect your eyes from the sun. they either change to a lighter color when exposed to low light conditions or they become darker when exposed to bright lights.
While choosing the right lenses is important when deciding on your prescription glasses you also need to look at lens coating. You can choose between scratch-proof, anti-reflective, and UV coating. Each offers its own benefits and will provide certain benefits that you cannot overlook. For example, anti-scratch coating keeps your lenses safe and protected against scratches. Anti-reflective coating on the other hand will improve the quality of vision, especially at night when your eyes will be hit by bright headlights from oncoming cars. UV ray coating is important because it helps to prevent eye cancer. Just make sure you ask for and get 100 percent UVA and UVB coating.
The bottom line is when it comes to choosing your prescription glasses, you need to look at a few important factors. First of all, you have to decide what kind of spectacles are right for you. Second, you need to pick the right lens material and third you need to ensure you use the right lens coating. As long as you address these issues, you won’t have any difficulty in choosing the best glasses.
