Even if you wear contacts, you may still want to protect your eyes from blue light. One of the easiest ways to protect the eyes from dangerous blue light is with blue light blocking glasses.
Many patients who would prefer to wear contact lenses are now getting computer glasses without a prescription that are equipped with a blue light filter and anti-glare coating. The blue light filter with anti-glare helps reduce eye strain and the damage that can be caused due to exposure to electronic screen usage and bright lights. It’s recommended that you wear prescribed eyeglasses that have anti-glare and blue light filters instead of wearing contacts at the computer. However, if you do want to wear contacts while looking at the computer then you can get some blue light glasses.
Computer Usage and Contacts
Too much computer usage can lead to less blinking, which can cause your eyes to become dry. Contact lenses already reduce the amount of oxygen to the eye. When you combine this with less blinking, it can cause additional eye strain, eye irritation, pain, headaches, and different eye issues, such as dry eyes. Those who suffer from dry eyes can also experience daily vision fluctuations and won’t ever be satisfied with the comfort and vision they get from their contacts. One day your prescription can look fine and then the next day it’s blurry. This fluctuation is due to the lower amount of fluid that is between the cornea and the eyes. Natural tears can work to improve the vision and comfort with contact lenses. Even if your preference is to wear contact lenses with glasses, it’s a good idea to have a balance between lenses and glasses. Wearing glasses some days and rotating contacts on the other days can allow your eyes to stay hydrated and heal. This combination promotes healthier eyes over time. Wearing glasses allows your eyes time to breathe.
This strategy will only work if you do have prescription strength blue blocker glasses. Your eye doctor can also help you come up with lenses that are comfortable for everyday use and you can still wear blue blocking glasses. It helps to also be sure to look away from the screen while working, whether you are wearing contacts or blue light blocking glasses.
What Is Blue Light?
The visible spectrum of light has a range of colors and blue and violet are on the lower end. Red is on the higher end. Light on the low end of the spectrum, like blue light, has the shortest wavelength. The shorter wavelengths have more energy and this is why blue light causes issues.
Can You Protect Your Eyes with Contacts?
There are intraocular lenses that can offer blue light protection. However, the amount depends on the type of lenses that are used. These lenses are not for everyone and are used during cataract surgery.
Benefits of Blue Light Blocking Glasses
Blue light can provide some benefits but too much can be harmful. Blue light glasses will help reduce the harmful overexposure to the light.
Blue light can be known to disrupt sleep. The blue light from the sun is responsible for wakefulness and increased energy. Falling asleep in front of the TV or checking emails before bed disrupts the natural sleeping patterns because you are exposed to blue light at night. Blue light blocking glasses can be helpful to ensure the blue light doesn’t disrupt sleep cycles.
Studies suggest that prolonged exposure to blue light can cause damage to the eyes. Everyone can experience digital eye strain after staring at a computer screen for a long period of time. However, now eye strain is more pronounced since many people spend a large portion of the day looking at computer screens and smartphones. Even when relaxing and reading on a tablet or watching TV, you are exposed to blue light.
Slow or Prevent Age Related Macular Degeneration:
There still needs to be some more studies done on macular degeneration but some early studies show that blue light can penetrate your eyes all the way to the retina. With blue light blocking glasses, you can mitigate some of the damage that then causes problems later on in life.
