As an alternative to wearing eyeglasses, a person may consider getting a contact lens prescription from an eye doctor. Contact lenses work by correcting vision in the same way as eyeglasses, but a person places them directly on the cornea of the eye.

People may also wish to consider laser eye surgery, which alters the shape of the cornea to rectify the type of vision impairment a person is experiencing.

If individuals wish to try alternative eyeglasses, they have a choice of other companies that offer similar eye products, including:

Research from 2010 shows that eyeglasses for those with vision impairment increase vision-related quality of life.

The Centers for Disease Control and Prevention (CDC) say that visual impairment is preventable in many cases if a person receives an early diagnosis. Therefore, the CDC recommends that people undergo eye tests regularly.

The organization lists some tips to help maintain eye health and prevent vision loss, including:

  • Undergoing dilated eye exams: A thorough eye exam can detect diseases such as glaucoma, diabetic retinopathy, and age-related macular degeneration.
  • Maintaining blood sugar levels: This is particularly important for people living with diabetes.
  • Knowing your family eye health history: Many eye diseases are genetic, so a person should be aware of any conditions that run in their family and inform an eye doctor about them during a test.
  • Eating a balanced diet: Dark leafy greens, such as spinach and kale, can help maintain eye health.
  • Using protective eyewear: A person can wear sunglasses or goggles when necessary.
  • Resting the eyes regularly when using computers: The CDC recommends the 20-20-20 rule, which instructs to look at something 20 feet away for 20 seconds, every 20 minutes of computer use.
  • Trying to quit smoking: The CDC states that smoking can increase the risk of developing certain eye diseases.
