Vision problems caused by prolonged computer use are common. A 2020 study published in the journal Cureus reported that computer vision syndrome—a condition characterized by headache, itchy eyes, and temporary vision changes—was higher in eyeglass wearers and those who reported glare on their computer screens.

While it's not an outright necessity, anti-reflective coating is something you may want to consider if you have symptoms of eye strain or spend a lot of time in front of a computer.

The educational objectives of the program leading to the degree Bachelor of Science in Engineering, Course 2-A are that:

The American Optometric Association lists eyeglass lens coatings as one of the more useful solutions for computer vision syndrome.

Recognize ethical and professional responsibilities in engineering situations and make informed judgments, which must consider the impact of engineering solutions in global, economic, environmental, and societal contexts.

Anti-glare glasses also may help people who are sensitive to light while driving in the daytime or those boating in bright daylight. AR coatings are available for sunglasses too.

The Institute is committed to generating, disseminating, and preserving knowledge, and to working with others to bring this knowledge to bear on the world’s great challenges. MIT is dedicated to providing its students with an education that combines rigorous academic study and the excitement of discovery with the support and intellectual stimulation of a diverse campus community. We seek to develop in each member of the MIT community the ability and passion to work wisely, creatively, and effectively for the betterment of humankind.

The Course 2-A concentration is a set of classes that includes 72 units or more of a subject related to a single cohesive focus area within the field of engineering. Students choose these subjects in consultation with the Course 2-A Coordinator, Professor Rohan Abeyaratne (rohan@mit.edu). A proposed course of study is developed and submitted online for review and approval. Certain restrictions do apply, and are outlined below.

Within a few years of graduation, a majority of our graduates will have completed or be progressing through top graduate programs; advancing in leadership tracks in industry, non-profit organizations, or the public sector; or pursuing entrepreneurial ventures. In these roles they will:

Develop and conduct appropriate experimentation, analyze and interpret data, and use engineering judgment to draw conclusions.

Bear in mind that the Course 2-A program was designed to be flexible. Many different concentrations are possible, and a student’s individual program may be unique. The example concentrations listed below serve only as a starting point. Students are encouraged to design and propose technically oriented concentrations that reflect their own needs and those of society. To reference the detailed guidelines regarding the Course 2-A concentration, please visit the link provided below.

Apply engineering design to produce solutions that meet specified needs with consideration of public health, safety, and welfare, as well as global, cultural, social, environmental, and economic factors.

These objectives have been developed by the faculty and students of the Department of Mechanical Engineering of MIT, with input from other constituents, in an attempt to comply with the mission of MIT as an institution. That mission, as stated in the current edition of the MIT Bulletin is:

Anti-reflective coating (also known as AR, no-glare, or glare-free coating) reduces glare by absorbing and redirecting reflected light. This allows more non-reflected light to pass through, leading to fewer visual disturbances. Unlike reflective lenses with mirror-like finishes, anti-reflective coatings are transparent with a very faint green or blue tint.

It is very common for people to notice dark or semi-transparent dots or squiggly lines in their vision from time to time. Some people describe them as ...

Course 2-A is a twist on the original Course 2 mechanical engineering degree, allowing a customizable curriculum in which students can hone in on their personal interests, such as robotics, entrepreneurship, or energy.

As is often the case, the MIT Department of Mechanical Engineering is leading the way. This time, it's in the area of undergraduate education, with the newly revamped Engineering, Course 2-A program. One of the first programs in the world to offer a customizable curriculum alongside a rigorous core consistent with our mechanical engineering program, and including the ability to concentrate in one of several modern engineering areas, the Department's Engineering, Course 2-A program is garnering a lot of attention in the US and around the world.

Communicate effectively with a range of audiences by diverse means including written reports, public speaking, and visual media.

Design and take responsibility for individualized program that integrates mechanical engineering with another discipline, and master material within the chosen discipline.

In the past, anti-reflective coatings were either painted onto the lens or applied to the lens like a sticker. But that's not the case anymore. Today, anti-reflective coatings are fused onto the lens matrix, a technology first employed with high-powered telescopes and microscopes.

The mission of MIT is to advance knowledge and educate students in science, technology, and other areas of scholarship that will best serve the nation and the world in the 21st century.

Specify manufacturing and fabrication techniques and other engineering processes needed to implement thermal and mechanical systems.

Many of the core requirements related to fundamental mechanical engineering coursework are the same across all three of our degree programs (Mechanical Engineering, Course 2; Engineering, Course 2-A; and Mechanical and Ocean Engineering, Course 2-OE). To make room for the flexible portion of the Course 2-A program, some of these requirements are relaxed, building the space for students to assemble their own "concentration," a collection of at least 72 units in an area of their choosing.

Anti-reflective coating on eyeglasses is designed to reduce glare, making nighttime driving easier, and reducing eye strain from computer use. The coating is fused into the surface of the lens, giving it a very faint blue or green tinge. Despite their benefits, anti-glare glasses tend to scratch easily and would then need to be replaced.

The STROBE Science & Technology Center brings together imaging science experts from seven universities and partners with national labs, industry and academe.

If you are considering anti-reflective coating, check the grading scale offered by your optician. Some opticians offer a choice of "good," "better," and "best" (or a similar scale) with the "best" grade costing considerably more.

Glare while driving at night is a common cause of accidents, especially for people with astigmatism. This eye disorder, which affects one in three Americans, can cause visual disturbances like halos and "whiteouts" with approaching headlights.

It's worth asking your optician about other available AR coatings. Manufacturers are constantly updating their materials and may offer superior products specifically designed for night driving, sports, or computer use.

Anti-reflective coating on eyeglasses costs more, but it may be beneficial in specific situations, such as night driving and preventing eye strain from computer use. On the other hand, the lenses are easily scratched and may require replacement.

Even so, a higher-end coating can be well worth your money. In addition to the benefits, these lenses tend to have better warranties and may be replaced at no charge if your lenses are scratched within a year.

The Engineering, Course 2-A program has been accredited by the Engineering Accreditation Commission of ABET, http://www.abet.org.

The coating is made up of carefully calibrated layers of metal oxides that are applied to the front and back of the lens and then irradiated with high-intensity ultraviolet (UV) light to enhance their light absorbency. This reduces reflected light and allows more non-reflected light to be transmitted through the lens.

According to Vision Center, AR coating can add $20 to $150 to the cost of lenses. Insurance may cover some or all of that cost.
