Buying inexpensive frames and having them fitted with your prescription lenses, is an affordable way to expand your eyewear collection while without compromising your vision.
Here are a few facts about purchasing generic frames for your prescription lenses:
- You'll need a valid prescription.
It's important to find frames that fit your face. There are three measurements to know: lens width, bridge width (the width across your nose), and temple arm length (the length of the arms).
The first number,the eye size, represents the horizontal width of the lenses. Generally, the eye size of most eyeglass frames ranges from 40 mm to 62 mm.
The second number, the bridge size, is the distance between the lenses. In other words, it's the size of the "bridge" of the frame that rests on your nose. In most cases, the bridge size of eyeglass frames ranges from 14 mm to 24 mm.
The third number, the temple length, is the length of the "stems" of the frame, measured from the frame hinge to the back tip of the temple. Temple lengths generally range from 120 mm to 150 mm.
- You may need add-ons to your prescription to help further protect your vision.
- Anti-Reflective Coating - Blocking reflections makes your eyes more visible and can reduce glare.
- Oleophobic Coating -This makes lenses more resistant to oil or fingerprints, which helps keep them clean.
- Scratch-Resistant Coating -This makes lenses more resistant — though not immune — to scratches.
- Ultraviolet Protection - UV exposure can hurt your eyes, so you want glasses that block 100% of UV light. Most lenses will block UV light without an add-on.
- Blue Light Filter - Computer screens emit blue light, which can make our eyes tired and interrupt our sleep cycles. Lenses with a slight amber tint can help block blue light.
- Polycarbonate and Trivex Lenses - These lightweight, durable lenses are ideal for glasses that will see hard wear.
- High-Index Lenses - Lenses with an index of 1.61 or higher are typically called "high-index lenses." The higher the index, the thinner the lens.
- Progressive Lenses - These are bifocal or trifocal lenses that don't have the typical line through the lens.
- Light-Adjusting or Photochromic Lenses - These lenses darken in the sun, so you don't need a separate pair of sunglasses.
Most importantly always check with your eye care professional before getting new prescription lenses.
Optometrist vs. Ophthalmologist vs. Optician?
- Visit an Ophthalmologist if you suspect you have a serious eye condition or may need surgery.
- See an Optometrist if you need an eye exam or to update your prescription.
- Go to an Optician to get your glasses or lenses adjusted, or purchase contact lenses.
