Prescription Glasses Research Paper

The demands of modern life can overwork the eyes and cause vision problems for the person wearing prescription glasses. However, this is a glass half-empty outlook. There are also useful vision hacks and lens options available for Nike prescription glasses owners. These can help you when you're in a tight fix or enhance your vision in ways you might never have considered. Below are six examples of these:

Read When You Don't Have Your Glasses by Using a Finger

If you find yourself at a store unable to read labels, or at a restaurant straining to read the menu because you forgot your glasses, there's another option besides squinting your eyes (which may not work for fine print). You can make a pinhole lens with your index finger. Form a small
aperture (hole) by curling up your index finger. Look through the hole at the print with one eye and the blurriness will disappear. For small lettering, hold the print closer. If the hole blocks out too much light, hold the print closer to the light.

Save Your Night Vision by Covering up One Eye

If you're out walking at night and need to use your smart phone, you can keep your night vision by covering up an eye. This prevents light from the phone from entering the covered eye and contracting its pupil. When finished with your phone, uncover the eye. One eye won't have night vision while the other will. This is enough to see where you're going until the other eye regains its night vision.

Use a Smart Phone for Seeing without Your Glasses

If you are nearsighted, your smart phone camera will let you see distant objects in perfect focus. The smart phone screen is, after all, close to your eyes. This hack comes in handy when searching for lost glasses at home.

Use Clear Blue Blocker Lenses for Seeing in Fog and Haze

Blue light doesn't focus well in the eyes. It also scatters while going through the eye's clear fluid. This always makes your vision less than crisp. Blocking out blue light with clear blue blocker lenses on your Nike prescription glasses eliminates this effect. This produces noticeable vision improvements, especially in fog, haze, and in falling snow. Clear blue blocker lenses also reduce computer eyestrain.

Some tint colors such as yellow do the same thing.
They have the disadvantage of reducing the overall light level somewhat, which reduces their effectiveness in low visibility conditions.

Use Brown Tinting for Improved Contrast

Brown tint improves contrast by blocking out blue light. Unlike blue blocker lenses, it's available for a wider choice of lens materials and reduces bright sunlight when outdoors. It works well for seeing birds, baseballs, and other objects silhouetted against the sky. Brown works well for any outdoor situation where better perception of texture, such as grass-blade orientation on golf courses or snow surface texture when skiing, is important.

Use an Anti-Reflective Lens Coating for Reduced Glare and Better Night Vision

An anti-reflective (AR) lens coating prevents light behind and above you from reflecting off the inside of your glasses and into your eyes. Headlights of cars behind and beside you, windows, lights and lamps inside a room, or overhead sunlight can reflect back into your eyes and interfere with normal vision. Because less light reflects from the front of your lenses, more gets through to your eyes, which improves night vision. Light reflection is especially acute with high index lenses, and safe driving isn't possible without an AR
coating.
