Eyeglasses or Contacts: Which to Choose?

How to Choose Blue Light Filter Glasses

8 May 2020 by Douglas Sutton

Electronic devices with screens emit light that allows you to see images and words created by pixels. However, this light, known as blue light, can cause sleep disruptions. Some people find it tricks their body's internal clock into thinking it's daytime, even when it's time to go to bed. This can exacerbate insomnia and make it hard to get a good night's sleep. Blue light can also contribute to eye strain.

Using electronics less can reduce your exposure to blue light. However, many people rely on computers, television, tablets, and phones for both work and entertainment. When you must use your electronics, you can lessen the effects of blue light by wearing blue light filter glasses. Blue light filter glasses ensure less harmful blue light reaches your eyes through the use of special lenses. Here are three tips that will help you choose the right pair:

1. Choose glasses you won't mind wearing in public.

Blue light glasses will only help if you wear them when using your computer, phone, or tablet. For best results, you should wear them every time you use a device that features a screen. Make sure you choose blue light glasses that appeal to you. If you're proud to be seen in your stylish glasses, you're more likely to use them when necessary.

2. Make sure your glasses fit well.

Blue light filter glasses are more effective when they fit well. Glasses that slide down the bridge of your nose constantly will let in blue light. You can purchase your blue light glasses from an optician who can custom fit them to your face. The process is similar to fitting any other pair of glasses. Your optician can make the necessary adjustments to the nose pads and arms of the glasses so they sit comfortably on your face.

3. Choose the correct level of blue light filtering.

Blue light glasses have lenses with a yellow tint that allows them to neutralize blue light before it reaches your eyes. The level of tint you require will depend on your sensitivity to blue light. If you want your glasses to be more discreet, you can choose glasses with a subtle tint. The lenses on these glasses can look just like ordinary glasses lenses. If you're very sensitive to blue light, choose a more aggressive tint to block as much light as possible.

These are just some things to know about getting blue light filter glasses. Contact local opticians to learn more.
