Sunglasses for men are a form of protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes. They can sometimes also function as a visual aid, as variously termed spectacles or glasses exist, featuring lenses that are colored, polarized, or darkened. In the early 20th century, they were also known as sun cheaters. The American Optometric Association recommends wearing sunglasses that block ultraviolet radiation (UV)
Whenever a person is in the sunlight to protect the eyes from UV and blue light, which can cause several serious eye problems. Their usage is mandatory immediately after some surgical procedures, such as LASIK, and recommended for a certain period in dusty areas, when leaving the house and in front of a TV screen or computer monitor after LASEK. It is important to note that dark glasses that do not block UV radiation can be more damaging to the eyes than not wearing eye protection at all since they tend to open the pupil and allow more UV rays into the eye.
Sunglasses can improve visual comfort and visual clarity by protecting the eye from glare.
Protection
Special protection is required for space travel because the sunlight is far more intense and harmful than on Earth, where it is always filtered through the atmosphere. Sun protection is needed against much higher UV radiation and even harmful infrared radiation, both within and outside the spacecraft. Within the spacecraft, astronauts wear sunglasses with darker lenses and a thin protective gold coating. During spacewalks, the visor of the astronauts’ helmets.
Which also has a thin gold coating for extra protection, functions as strong sunglasses for men. The frames of sunglasses and corrective glasses used in space must meet special requirements. They must be flexible and durable and must fit firmly in zero gravity. Reliable fit is particularly important when wearing corrective glasses underneath tight helmets and in space suits: once inside the spacesuit, slipped glasses cannot be touched to push them back into place, sometimes for up to ten hours.
Frames and Glasses:
Frames and glasses must be designed so that small pieces of the glass such as screws and glass particles cannot become dislodged, then float and be inhaled. 90% of astronauts wear glasses in space, even if they do not require corrective glasses on Earth, because zero-gravity and pressure change temporarily affect their vision.
Frames are generally made of plastic, nylon, metal, or metal alloy. Nylon frames are usually used in sports because they are lightweight and flexible. They are able to bend slightly and return to their original shape instead of breaking when pressure is applied to them. This flex can also help the glasses grip better on the wearer’s face. Metal frames are usually more rigid than nylon frames, thus they can be more easily damaged when the wearer participates in sports activities, but this is not to say that they cannot be used for such activities.
Protection:
Because metal frames are more rigid, some models have spring-loaded hinges to help them grip the wearer’s face better. The end of the resting hook and the bridge over the nose can be textured or have rubber or plastic material to improve hold. The ends of the resting hook are usually curved so that they wrap around the ear; however, some models have straight resting hooks. Oakley, for example, has straight resting hooks on all their glasses, preferring to call them “ear stems”.
Sunglasses for men offer protection against excessive exposure to light, including its visible and invisible components. While non-tinted glasses are very rarely worn without the practical purpose of correcting eyesight or protecting one’s eyes, sunglasses have become popular for several further reasons, and are sometimes worn even indoors or at night.
People may also wear sunglasses to hide an abnormal appearance of their eyes. This can be true for people with severe visual impairment, such as the blind, who may wear sunglasses to avoid making others uncomfortable. The assumption is that it may be more comfortable for another person not to see the hidden eyes rather than see abnormal eyes or eyes which seem to look in the wrong direction.
Contact:
Sunglasses for men can be worn to hide one’s eyes. They can make eye contact impossible, which can be intimidating to those not wearing sunglasses; the avoided eye contact can also demonstrate the wearer’s detachment, which is considered desirable (or “cool”) in some circles. Eye contact can be avoided even more effectively by using mirrored sunglasses.
Sunglasses can also be used to hide emotions; this can range from hiding blinking to hiding weeping and its resulting red eyes. In all cases, hiding one’s eyes has implications for nonverbal communication; this is useful in poker, and many professional poker players wear heavily tinted glasses indoors while playing so that it is more difficult for opponents to read tells which involve eye movement and thus gain an advantage.
Advantage:
When driving a vehicle, particularly at high speed, dazzling glare caused by a low Sun, or by lights reflecting off snow, puddles, other vehicles, or even the front of the vehicle, can be lethal. Sunglasses can protect against glare when driving. Two criteria must be met: vision must be clear, and the glasses must let sufficient light get to the eyes for the driving conditions. General-purpose sunglasses may be too dark, or otherwise unsuitable for driving.
Like corrective glasses, sunglasses have to meet special requirements when worn for sports. They need shatterproof and impact-resistant lenses; a strap or other fixing is typically used to keep glasses in place during sporting activities, and they have a nose cushion.
Fashion trends can be another reason for wearing sunglasses, particularly designer sunglasses from high-end fashion brands. Sunglasses of particular shapes may be in vogue as a fashion accessory. The relevance of sunglasses for men within the fashion industry has included prominent fashion editors’ reviews of annual trends in sunglasses as well as runway fashion shows featuring sunglasses as a primary or secondary component of a look.
Fashion Trends:
Fashion trends can also draw on the image of sunglasses and association with a particular lifestyle, especially the close connection between sunglasses and beach life. In some cases, this connection serves as the core concept behind an entire brand.
Various types of disposable sunglasses are dispensed to patients after receiving mydriatic eye drops during eye examinations.
The lenses of polarized sunglasses reduce glare reflected at some angles off shiny non-metallic surfaces, such as water. They allow wearers to see into water when only surface glare would otherwise be seen, and eliminate glare from a road surface when driving into the sun.
For water sports, so-called water sunglasses are specially adapted for use in turbulent water, such as surf or whitewater. In addition to the features of sports glasses, water sunglasses can have increased buoyancy to stop them from sinking should they come off, and they can have a vent or other method to eliminate fogging.
These sunglasses are used in water sports such as surfing, windsurfing, kiteboarding, wakeboarding, kayaking, jet skiing, bodyboarding, and water skiing.
