How to buy prescription glasses online?
To buy prescription glasses online, you should get a prescription and visit your local optician for an eye test. This test can be used not only to provide a prescription but also as a regular health check. Ask the optometrist for this data if you have had an eye exam and the optometrist provides a prescription. If you have an extra pair of glasses, send them to an online eyewear retailer to make sure the lenses have the correct 'visual center.' Measure the pupil distance. Ask your optometrist for this number, or get it from old glasses. Choose the right frame style to suit your face shape. Understand the frame measurements. Choose a suitable lens and its different lens film layer. Then place an order for glasses.
What is the progressive multifocal lens?
The lens of progressive multifocal glasses can change the refraction of the lens at the upper part of the central channel of the line of sight, which can effectively solve the difference of refraction when people view objects at different distances from long, medium, and short distances. Depending on demand, people have the flexibility to change or compensate vision according to visual distance, making it easier to help to adjust your vision in a variety of situations.
How are we nearsighted?
The light from external objects to the eye needs to be refracted by the lens before it can be imaged on the retina. The refractive power of the lens depends on the contraction and relaxation of the ciliary muscle. When we look at close objects, the ciliary muscles contract and the lens becomes thicker. When we look at distant objects, the ciliary muscles relax and the lens becomes thinner. Adjust the focal length of near and far objects so that they will show a clear image on the retina. If you use your eyes too often and the longer the ciliary muscles work continuously, the ciliary muscles will spasm because of too much tension. At this time, the lens cannot be adjusted and thinned. After the light from a distant object is refracted by the lens, the imaging position will fall in front of the retina instead of on the retina. Only a blurred image can be seen, which becomes myopia.
There is another situation. For some people, due to genetic factors, in the process of growth and development, the front and rear wheelbase of the eyeball will gradually become longer. In this way, although the adjustment function of the ciliary muscle and the lens is normal, the image formed will also fall in front of the retina due to the longer the axis distance of the eyeball, which can also cause myopia.
The two causes of myopia are different. Myopia caused by ciliary muscle spasm is called 'pseudo-myopia'. As long as the ciliary muscles are relaxed, myopia can be reversed. Myopia caused by the extension of the wheelbase of the front and back of the eyeball is called 'true myopia', which cannot be reversed and can only be corrected by myopia glasses.
What Is Anti Reflective Coating?
Anti reflective coating, also known as AR, anti-glare, no-glare, or glare-free coating, can provide benefits to your vision. Anti reflective coating is added to lenses to reduce glare caused by light hitting the back of the lenses to improve your vision and make your eyeglasses more visually attractive.
Anti reflective coating will eliminate all reflections from the front and back surfaces of your lenses. Hence, more light is able to pass through your lenses which improves your vision. At the same time, fewer distractions are visible and the lenses are hardly noticeable, especially in the dark. So, is anti glare worth it? Most people agree that.
How to Remove Coating from Plastic Glasses?
To remove coating from plastic glasses, you need to prepare some things which are etching cream, cotton buds or a small brush, rubber gloves, protective glasses and microfiber cloth.
Now, we will show you how to remove coating from glasses.
- With a cotton swab, scoop a little bit of etching cream. Carefully apply it to the whole surface of the lens. (both front and back).
- Let it sit for 5 minutes.
- With another cotton swab, do a little scrubbing around the surface of the lens. (both front and back).
- Wash thoroughly with soap and water.
Then repeat the processes if there is any coating left. After all steps are finished, you can successfully remove coating from plastic glasses.
