Some cleaning methods should be avoided to protect your lenses from scratches in the coating. As your eye care team, we’re here to offer advice and directions on caring for your new pair of glasses to keep them looking sharp and pristine.

In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams traveling in different directions. The directions of the beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element. Because of this, gratings are commonly used in monochromators and spectrometers.

Maintaining the look and effectiveness of your anti-reflective coated lenses requires gentle cleaning so they last. Cleaning your glasses is simple. You only need a microfibre cloth, water, and lotion-free dishwashing soap.

Transmission grating

A lot of products can cause damage to the lens coating on your eyeglasses that you may otherwise think are harmless, such as:

Taking proper care of your glasses can help them last longer without degrading their quality. If your lenses have a special coating to make your life easier, ask our optometry team how to best care for them.

Holographic grating

Schedule a comprehensive eye exam at The Eye Avenue to get an updated prescription and meet the opticians who can help you get your ideal pair of glasses.

Glare can also be common while driving at night, particularly among people affected by astigmatism, which can cause halos around streetlights. An anti-reflective coating can reduce the appearance of glares at night to help keep you safe and reduce eye strain.

Getting new, clean eyeglasses after an eye exam can be exciting—until they get dirty. Having dirt, dust, and fingerprints on your lenses can be distracting. Thankfully, you can always clean them!

Fraunhofer diffraction

Because of the nature of the coating, anti-reflective coatings on lenses can’t be repaired if damaged, so damaged lenses with coatings must be replaced to get the full benefit of the coating again.

In situations with elevated levels of glare, an anti-reflective coating can reduce eye strain, headaches, and eye irritation. Working on screens can lead to computer vision syndrome—also known as digital eye strain. Anti-reflective lens coatings can help some people manage symptoms caused by digital eye strain.

Always rinse your glasses with water at the outset, or use pre-moistened wipes if your optician recommends them. The moisture from water can help prevent damage caused by wiping debris away. If there’s debris caught in the nose pads or hinges of the arms, use a cotton swab to access those smaller areas.

When dirt shows up, it can be highly visible. Frequent, light cleaning can prevent dirt and grime from accumulating before they become visible.

Echelle grating

If your lenses have an anti-reflective coating, you must handle your eyeglasses carefully. You should gently clean your coated lenses with a microfiber cloth, water, and a gentle cleanser or dish soap to avoid damage to the lens.

Unlike the name suggests, an anti-reflective coating isn’t actually painted on the lens. Instead, it’s fused to the lens itself in layers to reduce reflection and let more light pass through.

When you notice your glasses are dirty, it’s tempting to reach for the closest solution, whether that’s the sleeve of your sweater or the hem of your shirt. However, these materials are heavily abrasive and can create scratches on the lenses.

Optometrics is one of the few manufacturers that offers in-house custom design and manufacturing of both ruled and holographic diffraction gratings – in standard and custom options.
