Why choose sunglasses?

Sunglasses are now a fashion accessory in addition to their function as such. They can give you a fresh feel as Mario Casas, Isabel Preisler glamor or the touch of a rock star Bono.

But apart from being a fashion accessory are an essential tool in protecting the health of your eyes and surrounding tissue. You should not jugártela to buy sunglasses, whether play sports, that price might harm your eyes in the long run.

Most sunglasses are designed to protect the eyes against the harmful effects of the sun. Often labels indicate sunglasses protection from ultraviolet light and other forms of natural radiation. It is important to know what kind of light you need to protect your eyes and what kind of light is not necessarily harmful.

Tips when choosing sunglasses

From the standpoint Felipe Zaragozí in the center of Altea we give you a few tips when choosing a model of sunglasses.

Blocking 99 percent of ultraviolet rays

Always buy sunglasses with this feature. Prolonged exposure to ultraviolet (UV) in sunlight is linked to eye cataracts and tumors, including cancer. UVB radiation is considered more dangerous to the eyes and skin than UVA radiation.

Both lenses of plastic and glass absorbs some UV light, but the UV absorption can be enhanced by adding chemicals to the lens material during manufacture or by applying special coatings of a lens.

Always look for sunglasses that block 99 percent or 100 percent of all UV light. Observe manufacturer’s labels as some say “UV absorption up to 400nm.” This is the same as 100 percent of UV absorption.

Ground and polished

Some glasses sold without prescription are ground and polished to improve the quality of the lenses. If you want to make sure that the lenses you buy are the right test to do the following: Look for something with a rectangular pattern as a table or a tile. Keep glasses at a comfortable distance and cover one eye. Move your eyes slowly from side to side, then up and down. If the lines stay straight, the lenses are fine. If the lines move, especially in the center of the lens, try another pair.

Sun glasses resistant to impacts

All sunglasses must meet impact standards set in the parameters of the manufacturers. Normally plastic lenses are less likely than glass lenses that could shatter when hit by a ball or a stone.

Most sunglasses lenses are plastic. Sunglasses polycarbonate plastic, used in many sports, which are particularly difficult to break, but are easily scratched. If you buy a pair of sunglasses with polycarbonate lenses, seeking those with scratch-resistant coatings.

Polarized sunglasses

Polarized lenses reflect glare of sunlight bouncing off smooth surfaces such as pavement, car windows, chrome surfaces or water. These may be particularly useful for driving and fishing.

Polarization has nothing to do with the absorption of UV light, but many polarized lenses are combined with a substance blocking UV (ultraviolet). Check the label to make sure the lenses provide maximum UV protection.

The lens and darkness

An average lens is good for everyday wear, but if you use the glasses for very bright conditions, you should choose sunglasses with a darker lens.

The color and degree of darkness does not tell you anything about the ability of the lenses to block UV light.

Photochromic sunglasses 

Sunglasses with photochromic lenses automatically darken with bright light and become clearer in low light. Most priming occurs about half a minute, while the clearance takes 1 to 2 minutes. When darken they are become a uniform color.

Sunglasses with wraparound style

Wraparounds are shaped to prevent light from shining around the frames bother the eyes. Numerous studies have shown that enough UV rays penetrate through glasses frames reducing the benefits provided by the lenses. Check the framed sunglasses protect your eyes from all angles.

Gradient lenses

Gradient lenses are permanently shaded from top to bottom or bottom-up halfway. Individual gradient lenses (dark on top and lighter at the bottom) can reduce the brightness of the sky, but allow you to see clearly below. They are useful for driving because they do not attenuate your view of the dashboard. They are not as good, however, to reduce glare in an environment with snow or at the beach.

Mirrored sunglasses

The mirrored glasses are trendy now and apart from the UV protection treatment have mirroring provides protection to solar glare.

You must be more careful with the care of these lenses should always be cleaned with water or with a suitable lens cleaning cloth and appropriate because any dust or dirt can easily damage the mirror and cause scratches on the lens that will be detrimental to the view, the only solution replacement lenses with new ones

Sunglasses block 90 percent of infrared rays

The infrared wavelengths are invisible and produce heat. Sunlight has low levels of infrared and infrared eye well tolerated. Some sunglasses manufacturers make health claims advertise their products based on infrared protection, but research has not shown a close relationship between eye disease and infrared rays.

Blue light blocked

The fact that blue light is harmful to the eye remains controversial. Lenses that block all blue light are usually amber and make your surroundings look yellow or orange. The tint supposedly makes distant objects appear clearer, especially in snow or fog. Therefore, sunglasses amber are popular with skiers, hunters, boaters and pilots.
