Glasses Q&A

Why do people wear eyeglasses?

Usually, people wear eyeglasses to correct refractive errors. Refractive errors mean your eye has difficulty focusing light, resulting in blurry vision until it’s corrected.

The most common refractive errors are:

  • Nearsightedness: Blurry far vision but clear close vision
  • Farsightedness: Blurry close-up vision but clear far vision
  • Astigmatism: Blurry close-up and far vision

Presbyopia is an age-related drop in focusing ability that often requires reading glasses. Many patients who have presbyopia are also shortsighted, meaning they need to have two different prescriptions to enable them to see at a distance and up close. 

The traditional method of achieving this is to use bifocals, where the top half of the glasses lens has the prescription for far vision, and the bottom half has the reading glasses prescription. Dr. Yu offers no-line bifocals, which use progressive or multifocal lenses that don’t have the unsightly line typical of bifocals.

Glasses allow you to see clearly when you have these refractive errors. 

What are the advantages of eyeglasses?

Contact lenses and laser eye surgery are increasingly popular among people with refractive errors. However, that doesn’t mean they’re right for you. Many people still prefer to wear glasses. They’re a convenient, effective option for correcting refractive errors.

Eyeglasses have several distinct advantages. Almost anyone can safely, comfortably wear them, and they’re far less likely to cause side effects than contact lenses. They’re also more affordable than contacts or surgery.

You may find eyeglasses are less of a hassle than contact lenses. Taking care of your glasses requires less work and effort. While you have to replace contacts at least every few weeks, glasses can last for years, and you may even keep the same frame while replacing the lenses with your updated prescription. 

Why should I wear sunglasses?

Sunglasses are more than just a fashion statement. They’re an important tool to protect your eyesight against damage from the sun’s ultraviolet (UV) rays, the same way you protect your skin from the sun. Dr. Yu recommends getting a pair of prescription sunglasses in addition to your regular eyeglasses. 

The best way to prevent the harmful effects of sun exposure on your eyes is to wear sunglasses with 100% UV protection whenever you go outside. They’re not just necessary for sunny days. UV rays make their way through clouds as well.

You might also find you’re more comfortable when you wear sunglasses. It’s both easier (and safer) to drive, bicycle, and go for a walk when you don’t have to squint all the time.
