How to Choose Your Perfect Pair of Prescription Sunglasses

Sunglasses are one of those fashionable accessories everyone loves to have but often forget to take care of properly. Sunglasses or sunglasses are also a popular type of protective eyewear mainly designed to avoid the bright sun and high-energy UV light from discomforting or damaging the eyes. For people who have these types of vision problems, it is important to know how to measure your sunglasses for proper fitting. The first step is knowing what your size is. Here are some ways you can determine your size.


To properly fit sunglasses

you must know what eye width is. This refers to the distance between your central vision and the outer peripheral vision. If you have a smaller vision, your distance will be elongated, while if you have larger eyes, your vision will widen. To get an idea about your size and ideal pair, it is best to stand in front of a mirror with your back firmly against it. Then, look at yourself and determine where your eyes are actually located – at the center of your forehead and along your hairline.


Your sunglasses should be designed

with a strong prescription in mind. This helps protect your eyes from harmful ultraviolet rays that may damage the cornea, cause pain or discomfort, and even lead to cataracts if not worn regularly. The prescription should also take into consideration factors such as your skin color and hair color among other things. Sunglasses that do not meet the prescription or are poorly matched to your skin color or other characteristics, can make you more susceptible to damage from sunlight, making you less resistant to its ill effects.


The intensity of your sun exposure

also affects how you should choose a pair of sunglasses. Long-term exposure to sunlight increases the risk of cataracts and can cause the development of macular degeneration or AMD. You should therefore choose a pair that has higher UV exposure than you usually do. If you normally spend most of your time indoors or you stay very long periods of time outdoors, it would be better for you to buy a pair that has reduced UV exposure. You should consult your optometrist to identify which sunglasses are best suited for your own personal needs.


It is always important for you to choose sunglasses

that will provide you protection against UVA and UVB rays. Your eyes are most susceptible to these harmful rays when you are outdoors. Both UVA and UVB rays have been known to cause the development of cataracts in older people. For this reason, you should avoid wearing sunglasses that are advertised to filter these harmful rays. Instead, buy a pair that provides you protection against only UVA rays. If you cannot find a pair of sunglasses that filters all UVA and UVB rays, it would still be a good idea to invest in a pair that has some type of filter so you can wear your sunglasses safely even when you are out in the sun.


There are different shapes and sizes of glasses

that you can buy as well. If you have a very large frame like a rectangle, you can buy sunglasses with larger frames to give you more peripheral vision. If you have a very small frame like an oval, you can get smaller glasses that will give you more comfort when you are working or doing other activities that require an extended visual field. You can also opt for bifocal shades if you need to wear two different shades. You can have the top shade black and the bottom shade can be white so you can read the paper or whatever you are doing while working. No matter what type of frames and shapes of glasses you buy, it is important that you get a pair of sunglasses with 100 percent ultraviolet protection.
