With neglect of the glasses and non-compliance with the conditions of their storage, scratches appear on the surface. In turn, this leads to image distortion, eye fatigue and visual impairment. About whether it is possible to remove scratches from glasses or still have to buy new optics, we will tell in our article. Consider several solutions to this problem based on the characteristics of the material from which the lenses are made.
Useful eyeglass tips
For storage of glasses, special covers are provided that protect the lenses from scratching. However, many people neglect this rule. As a result, their glasses are often subjected to mechanical stress from the outside. It is the non-compliance with the recommendations of optical experts that leads to the need to figure out how to remove scratches from glasses.
We can distinguish the following recommendations for the care of glasses:
- If a scratch is found, first contact an optician. Most likely, the specialist will be able to better remove this defect from the lens.
- If you often scratch your lenses, ask your optician for a protective coating for them.
- Never proceed to remove scratches from dirty lenses. Before starting work, wash them thoroughly in a warm soapy solution.
- If the anti-reflective coating deteriorates when removing scratches from the sunglasses, it is recommended to remove it completely with a cream, then visibility will improve significantly.
How to remove a scratch from the glass of glasses with toothpaste
Even improvised tools can be effective in dealing with scratches on the glass lenses of glasses. To do this, you only need a toothpaste without abrasive particles and soft felt. Also suitable is chalk, which will need to be pre-converted to powder.
Consider step by step how to remove scratches from glasses:
- A small amount of toothpaste is applied to a piece of felt.
- Circular motion polishes the surface of the lens. As you work, toothpaste can be applied to the tissue several times.
- It is strictly forbidden to use pastes with solid particles, which can further damage the glass.
- Similarly, you can remove scratches with chalk. It is slightly moistened with water and with the help of felt polished the surface of the glasses.
After polishing, the glasses are washed in warm water with soap.
Glasses scratch soda
This method is used if you were unable to find a non-abrasive toothpaste. How to remove scratches from glasses in this case, you can describe step by step:
- In a container with baking soda, such an amount of water is added so that a thick slurry or paste is obtained.
- A small amount of the prepared paste-like product is applied to the fabric and rubbed in a circular motion to the place where the scratches were found.
- The remnants of soda paste are washed off with warm water and soap.
Glasses cleaned from scratches dry in the air, after which they are wiped with a special microfiber cloth.
GOI paste for glass scratches
One of the most effective tools for removing scratches is GOI paste. This is a mixture of finely divided chromium oxide, active ingredients and fatty ligaments. By consistency, it can be either coarse or thin. This allows the use of paste for polishing optical glass.
There is no doubt about the effectiveness of the paste, but you need to figure out how to remove scratches from the glasses with the help of this widely known tool. To work more conveniently, it is recommended to remove the lenses from the frame (if they are screwed with screws). Next, GOI paste must be applied to felt or thick cloth, and the lens should be placed on top (with a scratched side on the fabric). In a circular motion of the lens, polish the surface. In order for the scratch to completely disappear, it will take a different amount of time, depending on the size of the damage to the glass.
After processing the surface of the lens, it will need to be washed in warm water from the remnants of the paste and inserted into the frame.
In this way, small scratches are easily removed. To remove more serious damage, you will need a grinding machine with a felt wheel, paste for polishing cars and GOI. This method is effective only when working with ordinary glasses, without tinting and special protective coatings, since the entire surface of the lens is exposed to processing.
How to remove scratches from plastic lenses of glasses
Even deep scratches from ordinary glasses are usually removed quite successfully, which can not be said about plastic lenses. As a rule, such glasses have an additional protective coating, which, when trying to get rid of damage to the optics, is immediately destroyed. In turn, new scratches will appear very quickly on uncoated lenses.
Before starting work, it is necessary to thoroughly clean the lens from dirt with microfiber. After that, a special abrasive containing hydrofluoric acid is applied to the plastic. As a result of the reaction, the upper plastic coating is removed along with scratches. However, this method is applicable only to plastic, but the glass surface from the reaction of hydrogen fluoride with silicon oxide will be hopelessly damaged. It is important that gloves are worn when applying the abrasive to the hands. After processing, the lenses are washed well in cold water.
Since this method completely removes the anti-reflective coating, it can only be called a temporary way to clean the surface of the lenses. In the future, it is still recommended to purchase new glasses.
How to remove scratches from sunglasses
In the manner described above, scratches are removed from sunglasses, the lenses of which are just made of plastic. For this, you also need an abrasive with hydrofluoric acid in the composition. Only before removing scratches on the glasses (solar), it is necessary to carefully prepare the surface and clean it from dirt. Then you need to proceed according to the instructions described in the previous paragraph.
If the sunscreen was of poor quality, then most likely it will deteriorate. Then with the help of a cream it is completely removed, after which the glasses are used for their intended purpose.
