It’s almost back to school time for unversity students and whether this is your first time away from home or you are already a pro, you want to be prepared with as much knowledge as possible to live safely on your own. This knowledge includes eye and vision safety, as failing to take care of your eyes today could cause damage to your eyes and vision now and in the future.
So put down your text books for a moment to review these four simple lessons from Dr. Dianna Leong, Dr. Anh Bui and Dr. Elizabeth Yan about protecting your precious eyes:
Blue Light Protection
College students spend a LOT of time in front of screens. From each class, homework assignment, and research project, to texting, YouTube , netflix and gaming - life is largely digital. This comes with a slew of potential side effects known as computer vision syndrome, including sore and tired eyes, headaches, neck, shoulder and back pain, dry eyes and blurred vision, largely due to the effects of viewing pixelation and the blue light emitted from the screens. Research shows that blue light can also impact your sleep quality and may possibly be connected to the development of retinal damage and macular degeneration decades later.
There are a few ways to protect your eyes and vision from blue light and computer vision syndrome:
- Use computer glasses or blue-light blocking coated lenses when working on a screen for long periods of time. These lenses are made to allow optimal visual comfort for working on a computer or mobile screen, by reducing glare and eye strain. They also block potentially harmful blue-light radiation from entering your eyes.
- Prescription glasses may be considered as well. Many students who never needed glasses previously experience eyestrain with extensive hours studying in university. A minor prescription can make a big difference in reducing eye fatigue and helping to improve concentration.
- Implement the 20-20-20 rule by taking a break every 20 minutes to look at something 20 feet away for 20 seconds. This allows your eyes to pause from the intensity of the computer screen.
- Depending on your environment, eye drops prescribed from the eye doctor may be helpful. Your blink rate often goes down substantially when you are concentrating on reading or computer work, which can cause dry eyes. Using eye drops and remembering to blink frequently can help reduce these uncomfortable symptoms.
- Install bluelight filters on your digital devices to reduce the amount of blue light exposure. There are a number of free apps available to download on your phone or computer.
Proper Contact Lens Use
Many college students opt for contact lenses as they are convenient and great for the appearance, but they come along with responsibility. The busy days and late nights can sometimes make contact lens care difficult so make sure to plan ahead. If you wear contact lenses you need to make sure that you always get them properly fit from your eye doctor, and that you follow your eye doctor’s instructions for proper care. Many “exclusive” online contact lenses may actually fit poorly using older technology lens materials. One size does not fit all.
Always follow the wearing schedule and never sleep in lenses that are not designed for extended wear. Clean and disinfect as needed, and don’t rinse them with anything other than contact lens solution. Failing to follow the proper use and hygiene for contact lenses can result in irritation, infections and even corneal scarring which can result in vision loss. One-day disposable lenses can be a convenient option especially for busy students who don’t have time to clean or store contact lenses.
Ultraviolet rays from the sun are known to cause long term eye damage and lead to vision threatening eye conditions such as macular degeneration and cataracts. Additionally in extreme cases of unprotected UV exposure you can get sunburned eyes, known as photokeratitis, which can cause a gritty, dry feeling, burning, swelling, light sensitivity, vision changes and sometimes serious pain. These symptoms typically go away within a day or two. Wearing 100% UV reflective sunglasses whenever you are outside - rain or shine - is a first step to eye protection. A large brimmed hat to protect the eyes from exposure from the top and sides is also a recommended addition for sunny days.
Get a regular eye exam
To start off college with the right foot forward, it’s recommended to get a comprehensive eye exam prior to the start of the the school year, especially if you haven’t had one recently. This way you can ensure that your eyes and vision are in top shape and, if you wear glasses, that your prescription is still accurate. The last thing you want to worry about when getting adjusted to college is problems with your eyes and vision.
It’s also recommended for students that are going away to another city to get a recommendation for a local eye doctor in case of an emergency. Most eye doctors know of colleagues located in other cities who they could recommend.
Just remember to think about your eyes because the better you take care of them now, the healthier eyes and vision you will have down the line.
