Everyone who is exposed to sunlight will need to wear sunglasses to protect from the sun's harmful UV rays. However, there are some individuals with an increased vulnerability to the sunlight and there are even some that are sensitive even to artificial light. There are also those that need to wear sunglasses because of their hobby or profession.
Here are some people who need to wear sunglasses
Those taking photosensitizing drugs. Some patients take drugs to deal with a certain illness. However, these drugs may cause photosensitivity as part of the side effects. Photosensitivity causes inflammation of the skin since the skin (as well as the eyes) becomes overly sensitive to light. Medications for cancer, psoriasis, acne, depression, diabetes, as well as anti-inflammatory, anti-bacterial, anti-parasitics, diuretic and antibiotic medications are some drugs that may cause photosensitivity. Since they are more sensitive to light, they need to wear DG sunglasses that have UV-absorbent and UV protection capabilities.
Those who have photophobia. This is a condition where a person is severely sensitive to light, even normal light. This sensitivity results in pain when exposed to light. Photophobia is commonly a symptom that points to another medical condition or infection. Sunglasses can ward off the pain since less light is able to penetrate into the eyes.
Patients who have undergone cataract surgery. Cataract surgery is more common that you think. There are around one million people who undergo cataract surgery annually. During this procedure, the cloudy lens of the eye is either scraped or removed and replaced with a synthetic lens. Newer synthetic lenses are now more UV-absorbent. However, the older synthetic lenses are not as effective in absorbing UV rays. This leaves the eye especially susceptible to the sun's rays. Even recipients of newer synthetic lenses should wear sunglasses to provide more protection against the sun.
Children. Children's eyes are not yet fully developed and have clearer lenses and larger pupils. This enables more light to pass and penetrate the eyes. Thus, it is vital for kids to wear a pair of wayfarer sunglasses when they go out into the sun.
Contact lens wearers. There are contact lenses that absorb and protect from UV rays. However, there are also some that do not. To be doubly sure, contact lens wearers should wear sunglasses.
Long-distance air travelers. Jet lag is a common result of traveling by plane for long distances. Jet lag is caused by the changes in a person's bio-rhythms as he goes through a number of time zones. Wearing choppers sunglasses limits the amount of light that penetrates the eyes, thereby "convincing" your body that it did not go through the various time zones.
Those whose profession results in an increased exposure to UVA and UVB rays. Some examples would be dentists, dental technicians and surgeons that make use of laser technology, as well as factory or construction workers that make use of welding torches. Wearing sunglasses should be part of these professions' safety equipment.
This is a long list; however, this does not mean that sunglasses are the answer to all situations. There are some instances where sunglasses will not be an effective protective device for your eyes. For instance, sunglasses will not provide adequate protection from light exposure when you are looking at a solar eclipse or are using tanning lights or arc welding equipment.
Since sunglasses are such a need for the above individuals, it is best to have sunglasses in bulk so that one has a pair whenever it is needed. You can even be fashionable without spending a lot by buying wholesale sunglasses by the dozen.
